00:00:04
[intense music] - When a murder's committed, it's always a race against time to find the truth,
00:00:12
to separate fact from fiction, to catch the killer, and to make sure that justice is served.
00:00:20
But what happens when the truth vanishes with the victim? I'm Dr. Richard Shepherd,
00:00:26
and I've spent my entire career as a forensic pathologist performing nearly 23,000 autopsies.
00:00:35
I've learned that the dead don't hide the truth and they never lie. Through me, you'll be hearing directly from the victim.
00:00:45
With the aid of a state-of-the-art laboratory using groundbreaking technology, I'll be investigating a series of intriguing crimes
00:00:54
where from the victim's bodies are revealed to you the truth behind these murders.
00:00:59
[camera clicking] [mysterious music] Little Venice in London is famous for the houseboats
00:01:12
that make their way along the Grand Union Canal. But in May, 2015, this picture-postcard location
00:01:21
became a crime scene when a member of the public made a shocking discovery. [circle beeping]
00:01:33
- In the Little Venice area of west London near to Paddington Railway Station, it's an area where quite a lot of people live on barges
00:01:40
as their place of residence. And two people were in a canal boat and heard a noise against the side of their boat,
00:01:48
which caused them to look outside, and they saw a suitcase in the canal. [foreboding tune]
00:01:56
- The two friends on that house boat looked down into the water and saw distinctive red hair flowing out of it.
00:02:04
[buttons beeping] - They became very concerned and decided to call the police. - But police obviously need
00:02:13
to essentially find out what's happened. So, being able to recover the suitcase from the canal,
00:02:19
which is, in itself, potentially quite challenging task because it's in the water,
00:02:23
so police have got to make a decision as to whether they enter the water or not.
00:02:27
If they're able to actually reach and remove the item without entering the water,
00:02:31
that is obviously safer. So, they've gotta consider that. Then also, the actual weight of the suitcase.
00:02:36
Because at that point, they don't know what's in the suitcase, and it's in a body of water,
00:02:40
so it may well be full of water, which will add to the weight. - [Richard] Having retrieved the suitcase,
00:02:45
police and forensic teams were shocked at what it contained. [camera clicks] - What was found in the suitcase was a body
00:02:54
that had been placed essentially in the fetal position. The body was wrapped in bin bags,
00:03:01
and also, a curtain was placed in the suitcase. [camera clicks] - When a body's found in a suitcase in a canal,
00:03:08
that's a homicide. That's a suspicious death. - [Richard] The police immediately launched
00:03:13
a murder investigation. - The first thing that they will need to do is identify who that person is in the suitcase
00:03:24
because it'd be very difficult for the police to find out who killed them without knowing who they are.
00:03:28
[zipper zipping] - So, the police looked to the body for answers. The body that was found in the canal
00:03:39
was folded inside a suitcase. It was in the fetal position and wrapped in curtains and bin bags.
00:03:45
There was no ID, no purse, no other obvious identification, but it's still possible for this body
00:03:52
to reveal a lot of information, even if the body is reduced to simply a skeleton.
00:03:58
If you know how to read bones, you can get a lot of information from that. The age of death, the height,
00:04:04
and from the shape of the pelvis, the sex of the individual. Some decomposition had set in, but the organs,
00:04:11
tissues, and skin were still largely intact, thanks to the cooler water temperature of the canal,
00:04:17
which slowed down the rate of decomposition. So, a body like this, where there is still soft tissue, has many more secrets
00:04:26
it can reveal to a forensic pathologist. In the mortuary, the body can be measured and weighed
00:04:32
and the teeth can help determine the age too, since they erupt throughout life. For instance, the wisdom teeth appear in your 20s.
00:04:42
In this case, the body had its wisdom teeth. And the shape of the pelvic bone indicated it was female.
00:04:49
From all this, it could be determined with some certainty that she was a white woman,
00:04:54
approximately five foot two, weighing eight stone, and it was clear that she was young,
00:05:00
in her early 20s. But there was no missing persons report for anyone like that. So, who was she?
00:05:08
[mysterious music] With, little to go on, even forensic evidence proved limited.
00:05:16
- Ultimately, when somebody's body is in water, it's likely to remove things like DNA,
00:05:24
opportunities to recover evidence. For me, the most important thing is to make an appeal via the media, via all forms of media,
00:05:32
asking for witnesses to come forward, asking for people to report in anybody that they're concerned about,
00:05:39
to try and work through opportunities to identify who the person is. Because once that's established,
00:05:45
it opens up a vast array of other opportunities to identify if there are any other scenes
00:05:50
that need to be cordoned and searched and examined, because, for example, where she was actually placed into the water,
00:05:58
if it was different to where the suitcase was found. [soft somber music] - [Richard] Then detectives got a breakthrough.
00:06:15
A man called Tomasz Kocik contacted police to report his girlfriend missing. Kocik later identified the body as that of Marta Ligman.
00:06:29
Journalist Henry Vaughan remembers the case well. - I first heard about the case of Marta Ligman
00:06:36
when her body was discovered in a suitcase in the Grand Union Canal. I was working as a court reporter at the time.
00:06:44
It's a very unusual set of circumstances, so that is something that sticks in the mind.
00:06:52
- Marta Ligman came to the UK in 2012 and she worked in a delicatessen in Halston in northwest London.
00:06:59
Very highly thought of by her boss, described as a very pleasant girl with aspirations to get married,
00:07:05
to have a family to settle in the UK, the very, very pleasant demeanor, very helpful and outgoing.
00:07:13
- She'd come over from Poland to the United Kingdom to live and work and make a life for herself.
00:07:20
A very brave thing for her to have done, actually. - She was very popular, had lots of friends,
00:07:28
and well liked by everyone who knew her. - [Richard] In London, Marta moved in with her Polish boyfriend, Tomasz Kocik,
00:07:37
who she'd first met back in Poland. - Marta met Kocik on a internet chat room.
00:07:46
[keyboard keys tapping] - Both Polish nationals, so they formed a friendship, formed a relationship.
00:07:54
- Tomasz Kocik was quite a bit older than Marta, around 38 at the time. He was also from Poland and lived in London
00:08:02
working as a forklift truck driver. He'd also spent some time in Ireland before moving to the UK.
00:08:09
- That relationship then developed into what seemingly was a very, very affectionate, loving relationship.
00:08:17
To the extent that Marta took the decision to move from her home in Poland to London,
00:08:23
a big step for her to set up home really with Tomasz Kocik. - She probably went into that relationship feeling so happy,
00:08:37
so excited, and she may even have fallen for him before they physically met. She may have fallen for him whilst they're still,
00:08:44
you know, maybe talking online. - At the start, they seemed to have a very good relationship
00:08:50
and she was very happy. Their neighbors said they seemed like a perfect couple and also that Kocik seemed quite protective of Marta.
00:08:59
- Kocik was around 15 years older than Marta. He was a builder by trade and came into this country purely for work purposes.
00:09:10
He was a very caring person towards Marta. He was always concerned about her wellbeing
00:09:16
and he wanted to look after her, so they had a very happy and settled relationship.
00:09:21
Marta wanted to get married, she wanted to have children, and she thought when she met Kocik
00:09:27
that that was his dream as well. "This is what I want, too. I want a wife, I want a family, I want children.
00:09:33
I'm very traditional." So, that would've played into everything that she wanted.
00:09:42
- To people from the outside, seemingly very happy. - [Richard] So, how did this young woman's life
00:09:48
end so tragically? - Things can change literally overnight. [dark tune] [dark tune]
00:10:03
[mysterious music] - In 2015, police launched a murder investigation after the body of 23-year-old Polish delicatessen worker,
00:10:14
Marta Ligman, was found folded into a suitcase and dumped in a London canal. [slow dark music]
00:10:22
- When her body was found in a suitcase in the Grand Union Canal, it's a very unusual set of circumstances,
00:10:29
so it was an immediately a high-profile case. - It's important to recognize that the location
00:10:35
where Marta's body was found in the canal is not necessarily the same as the deposition site,
00:10:40
i.e., where the suitcase entered the canal. And also, there may be other locations
00:10:46
where events have taken place that would inform the investigation about the events that led to Marta's death.
00:10:52
- There were witnesses who had seen the suitcase in the canal and dismissed it without causing any suspicion
00:10:59
in their minds about the suitcase. But it had traveled a significant distance to the point of Little Venice,
00:11:05
where Marta's body was discovered. - However, what may well be preserved, because of the fact that Marta is enclosed
00:11:13
within the suitcase, is evidence of injuries or evidence that would be later inform
00:11:18
the investigation as to how she died. [mysterious music] - The post-mortem showed she'd been in the canal
00:11:29
for between seven and 10 days. We can estimate this because the water in the canal
00:11:36
where Marta's body was found would've been colder than the air temperature,
00:11:40
and therefore slowed down the decomposition of her body, making it easier to determine the exact time of death.
00:11:48
We know that she was folded up very tightly in a small space with her knees up to her chest.
00:11:55
This position would've limited movement of the rib cage and stopped air being drawn into her lungs.
00:12:02
It would've been almost impossible to get her folded into that tight space unless she was immobile.
00:12:09
But what we don't know is whether she was dead when she was put into the suitcase or just unconscious.
00:12:16
And the terrible truth is that Marta might still have been alive when she was thrown into the canal.
00:12:23
[slow intense music] - The most distressing detail that the pathologist could not rule out
00:12:33
that Marta was not alive or dead when she was placed into the suitcase. - [Richard] In their hunt for the killer,
00:12:41
police needed to eliminate the most obvious suspect from their inquiries. The man who'd first reported her missing,
00:12:48
her boyfriend, Tomasz Kocik. - We know that the most likely person to kill any woman
00:12:57
is their partner or ex-partner. So, intimate partner homicide, that's where a man kills his partner, or ex-partner,
00:13:05
is actually the biggest category of homicide for women. So, as soon as murder is identified,
00:13:12
Kocik is at the top of the list straight away. [foreboding tune] - Kocik was 15 years older than Marta Ligman,
00:13:21
and I think it's quite important just to consider that when they met online, Marta was a teenager.
00:13:27
- That is a bit of a red flag because statistically, somebody much older than a woman especially
00:13:36
is going to be targeting them because they are more malleable, they are more vulnerable, they're less experienced in life.
00:13:46
- So, I think in terms of power imbalance and the dynamic within the relationship,
00:13:50
he was likely to be more sort of influential in the way that things were within the relationship,
00:13:56
which, again, could have affected the way that they live their lives together and subsequent events.
00:14:04
- There are extra risks, I think, to meeting somebody online. It's very easy to present yourself as something
00:14:14
other than you actually are online, and it's very, very difficult to question any of that.
00:14:21
And if you do those first few meetings online, by the time you are face-to-face with that person,
00:14:27
you think you already know a lot about them, and so your instincts in that first face-to-face meeting
00:14:34
will be very much dampened. [slow dramatic music] - Marta had lived in the UK for about three years,
00:14:52
and friends have noticed that Marta's behavior had started to change, so she'd become quieter, more reserved.
00:14:59
And some concerns generally were being noted by people that knew her or they felt that something was not quite right
00:15:06
in the relationship. - The changes in her started to happen quite quickly. She started to withdraw, she started to lose weight,
00:15:15
she started being less happy, seeing less of her friends, and and that concerned them.
00:15:24
- Kocik became very controlling, and her friends said she wasn't the sort of happy-go-lucky person she used to be.
00:15:31
- [Richard] Within three years, Kocik had also become obsessively jealous about Marta.
00:15:37
- As time developed during their relationship, things began to take a turn for the worse.
00:15:42
His behavior became more controlling, more coercive, and even obsessive about Marta's movements and her whereabouts.
00:15:49
- And he was very intense about it. Every single thing she did, he was there. He was following her, he was tracking her,
00:15:55
he was isolating her. - And asking a lot of very searching questions and generally exhibiting an area of suspicion
00:16:03
about the way that Marta was behaving without any grounds that are known of, but just a very controlling kind of approach
00:16:12
taken by Kocik at that time. - He would turn up at her work. Every day, he'd pick her up from her work
00:16:19
'cause he didn't trust her. There's even one occasion where he demanded that the boss
00:16:24
of the deli she worked in show in the CCTV to prove that she'd been working there.
00:16:29
- And that was quite concerning to her boss. [foreboding tune] - The first control that always comes in
00:16:37
is what we call jealousy code. So, he would've been saying things like, "Don't like it when you talk to other men.
00:16:44
Makes me feel really, really jealous. Don't do it." And she probably thought, "Oh, fair enough.
00:16:48
Well, I won't do that. I'm not gonna wind him up." But there would've come a point
00:16:52
where she did something to break that rule, not on purpose, and he would've punished her for it,
00:17:00
and that punishment was set the tone for everything that happens going forward. [dark mysterious music]
00:17:12
- One of her friends recalled an occasion where Marta wore some very thick rimmed spectacles,
00:17:17
and what the friend thought was to try to hide the fact that she had some facial bruising.
00:17:22
- This made everyone very concerned about Marta's wellbeing. - The behavior progressed
00:17:27
to essentially monitoring Marta's behavior, moving more towards what can generally be described
00:17:33
as a controlling or coercive type relationship. - People who are controlling and who use coercive control
00:17:42
are actually trying to trap you into a relationship with them. So, that means that you can't get out of this relationship.
00:17:50
"You've committed to me. You can never leave" - To build the case against Kocik being the killer,
00:17:57
police needed to know if Marta's body revealed signs of a controlling and abusive relationship.
00:18:03
So, what could Marta's body tell us about the final tragic hours of her life?
00:18:09
When Marta's body was removed from the suitcase, it was evident she'd suffered a severe beating.
00:18:15
She had numerous injuries to her face and her body that must have been inflicted
00:18:19
in the hours before she was thrown into the canal. But she also had other injuries that were older.
00:18:26
Bruises can be aged because they change color over time, going from purple and blue to yellow and green,
00:18:33
and finally to brown. Marta's body was covered in old and fresh bruises, but it's the fractures that are most revealing.
00:18:42
A recent fracture looks like this. And here, you can see the clear separation in the bones.
00:18:48
But these broken ends will knit back together over a period of weeks and months.
00:18:53
And Marta also had several healed fractures. So, what her body revealed was that she had been subjected
00:19:00
to a prolonged and savage attack immediately before her death. But it also showed that this was part
00:19:08
of a long history of physical abuse. - Older injuries would be consistent with what the friends had described
00:19:15
in terms of there being a deterioration in the relationship and more violence being used towards Marta.
00:19:22
[intense music] - Kocik used to play loud music in the flats, which is believed to have covered up him beating her.
00:19:32
[intense music continues] - So, I think she did something trivial or something that he made up
00:19:39
and he probably really, really hurt her, but that's a warning for the future.
00:19:44
"That's your punishment." It's what we call the three Cs, so it's control, challenge, consequence.
00:19:53
So, the control is in place, rules of the relationship. "You will not make me jealous."
00:19:59
There's some kind of challenge to that. Maybe she's caught speaking to somebody.
00:20:03
What are the consequences? The third C, violence. Now, the consequences reinstate the control.
00:20:11
She thinks, "I'm never gonna do that again. I am never gonna speak to another man"
00:20:17
Or, "I'm just never gonna do anything ever to upset this man 'cause I'm now scared of him."
00:20:23
She was literally trapped like a hostage in this relationship with him. - [Richard] There was still no hard evidence linking Kocik
00:20:34
to the assaults or the murder. But Marta's phone messages were raising further suspicions
00:20:40
among friends and colleagues. [mysterious music] - The boss at the delicatessen received a message
00:20:53
basically to say that Marta was not gonna attend work because her mum was sick in Poland and needed to leave,
00:20:59
which was described as being out of character for Marta, that Marta would not have sent a message that way.
00:21:04
She would've gone into the shop and explained. Also, messages were sent to Marta's friends
00:21:12
to explain that she'd left Kocik. So, there was quite an amount of communication
00:21:18
from Marta's Facebook account and from her device. - On Facebook Messenger, sending one of her friends
00:21:30
about 50 messages they exchanged between them. The friends initially believed she was talking to Marta,
00:21:38
but she became suspicious when the messages began to start suggesting a threesome.
00:21:43
- The level of conduct and the content of the communication caused some alarm to Marta's friend
00:21:50
as it also included activity about engaging in sexual conduct together. Marta's friend clearly thought this was uncharacteristic
00:22:02
of Marta, and it raised alarm bells in her head. She went straight to her home address
00:22:07
to see if she was okay, but nobody was at home. [dark tune] [dark tune] [somber music]
00:22:31
- In London in May, 2015, the body of 23-year-old Marta Ligman was found folded up in a suitcase
00:22:38
floating in London's Grand Canal. The post-mortem revealed bruises and fractures,
00:22:44
proving that she'd been subjected to a long history of physical abuse. The prime suspect was her boyfriend, Tomasz Kocik.
00:22:54
Messages sent from Marta's phone and computer before her body was found suggested she had left her boyfriend and returned to Poland,
00:23:02
but these didn't seem in character. Friends and family feared she was missing.
00:23:08
- It was quite common for Marta to speak to her mum on a very regular basis, if not daily.
00:23:14
So, obviously, Marta wasn't doing that. - Her lack of contact with friends and family, again,
00:23:20
against her demeanor, uncharacteristic of Marta not to speak to her mother every day.
00:23:26
- Then Marta's mum made contact with Tomasz Kocik to establish what had happened,
00:23:31
and he explained that Marta had left him, which also fitted with messages that were being sent
00:23:38
purporting to be from Marta. - [Richard] But once Marta's body was found, it became clear to police
00:23:45
that she could not have sent those messages. She was already dead in the canal. The only person with access to Marta's devices
00:23:55
to send messages was Kocik. - Kocik made contact using Marta's Facebook account.
00:24:02
He messaged one of her friends. The messaging was uncharacteristic of Marta. It alerted her friend immediately
00:24:10
that potentially, there could be a problem. - So, there was a clear attempt by Kocik
00:24:16
to mislead a number of people that knew Marta and were clearly gonna ask questions about where she was.
00:24:22
- He was just trying to make it all go away, stop anyone reporting her missing, and maybe give himself some time to think.
00:24:34
In creating this kind of web of lies, trying to convince everybody maybe that Marta's still alive
00:24:42
so that he stops people coming to look for her, 'cause he knows his name's gonna be at the top
00:24:46
of the list if she is found and identified. [foreboding music] - Kocik didn't report Marta missing.
00:24:54
And despite her mother phoning him and asking him to look for her and ask what he was doing to try and trace her,
00:25:03
he didn't report her missing until her body was found, which was around 10 days later.
00:25:09
[slow foreboding music] - This case attracted heavy media attention. And as a result of that, Kocik was alerted to the fact
00:25:22
that Marta's body has been found, and that was the point that he contacted the police
00:25:26
to report her as missing. In fact, members of her family had tried to ask him to report her as missing
00:25:34
previous to the date of her body being discovered. Kocik simply refused to do so.
00:25:41
- The fact that he hadn't reported a missing until Marta's body was found in the canal
00:25:46
clearly caused suspicion and ultimately led to the arrest of Kocik as a suspect for Marta's murder.
00:25:52
[foreboding tune] - [Richard] But under police questioning, Kocik denied murdering Marta.
00:26:00
- He did not accept that he killed Marta and denied his involvement in the murder of Marta.
00:26:06
- The explanation that Kocik gave was that he had come home from work and found Marta dead.
00:26:12
He thought that Marta had had a heart attack because he and Marta had been taking amphetamines
00:26:18
in the preceding days. - Kocik was fearful that he would be in trouble with the police for providing her with those drugs.
00:26:26
His version of events was that he panicked. - They'd been involved in rough sex activity,
00:26:30
as he described it, and he felt that those things combined would cause him to be blamed effectively for her death.
00:26:40
- But did Marta's body support Kocik's version of events? Kocik claimed that Marta had died
00:26:47
from an amphetamine overdose, following days of drug-fueled bondage sessions. And although internal swabs were taken,
00:26:54
there was no evidence of recent sexual activity. Amphetamines can be detected in the bloodstream
00:27:00
for, on average, 48 hours after being consumed, and on human hair, as long as 90 days afterwards.
00:27:10
Some amphetamine users take the drug through what is called skin popping. These are subcutaneous injections that go into the tissue
00:27:18
rather than the blood vessels. And what we would see then is lots of ulcerated areas on the legs and forearms,
00:27:26
but there was no evidence of this on Marta's body. If she was injecting, there would be track marks,
00:27:33
and there was no evidence of that either. - He said that he came home and found Marta dead on the sofa, and she had problems
00:27:43
and she was taking drugs and she'd obviously overdosed. And the most classic way to defend yourself
00:27:49
against killing somebody you're supposed to love is to denigrate them in some way
00:27:53
and make them responsible and make you the innocent victim of their awful behavior.
00:27:59
And that's what he did. [somber music] - [Richard] Kocik did, however, admit disposing of Marta's body.
00:28:13
- Eventually, as the evidence unfolded and was presented to him and his legal team,
00:28:17
he changed his version of events. He admitted that he did conceal her body in the suitcase.
00:28:26
- He confessed to the police that what he then did was place Marta into the suitcase.
00:28:31
He walked down the distance of about half a mile and placed a suitcase in the Grand Union Canal
00:28:37
near to Scrubs Lane. - The suitcase then traveled in the direction of Little Venice
00:28:43
down the canal for a significant period of time. - Scrubs Lane is about two and a half,
00:28:52
maybe three miles, from the Little Venice site where Marta's body was ultimately found.
00:29:02
As a result of Kocik's account, one of the things that the police will do is check
00:29:07
and try and corroborate an account that's given. [camera whirs] That could include CCTV.
00:29:11
[audio distorts] The CCTV revealed that Kocik had walked from the home address to the Grand Union Canal,
00:29:18
a distance of about half a mile. [foreboding music] - He was seen wheeling the suitcase
00:29:31
on his way to the canal along a number of streets past commuters towards the canal,
00:29:39
carrying this heavy suitcase, which was so heavy on CCTV. You can see that the wheels were buckling.
00:29:45
[water splashes] He'd also taken a stick with him in attempt to submerge the suitcase.
00:29:54
- And then shortly after that, he was seen again walking back towards his home address,
00:29:59
this time without the suitcase. From the waist down, it was noticed on the CCTV he appeared to be wet,
00:30:06
which would be consistent with the fact that he had been in the canal, seeking to dispose of the suitcase
00:30:11
in the way that he described. - This man didn't have many resources. He didn't appear to have a vehicle.
00:30:20
I think if he had a vehicle, he might not have chosen the canal. Throwing a body into a canal is a high-risk strategy
00:30:31
because bodies tend to be found when they're in bodies of water that are quite small.
00:30:37
- [Richard] While CCTV footage confirmed Kocik's story that he disposed of the body,
00:30:42
there was more to come. [mysterious music] - [Steve] You know, with that extra understanding
00:30:51
of what the events were and confirmed now by the CCTV, that enabled the police to search areas
00:30:57
where they knew that Kocik had traveled. And that led to the recovery of identity documents belonging to Marta.
00:31:06
- Of great significance was that en-route to and from the Canal, Marta's identification card was found damaged and burnt.
00:31:14
Again, evidence of Kocik trying to conceal her identification from the police. - And that confirmed and corroborated
00:31:25
and supported the understanding of what had taken place in Marta's death. [foreboding tune]
00:31:31
- [Richard] With evidence that Kocik had tried to conceal Marta's identity, police charged him with murder.
00:31:39
[intense music] - I've prosecuted a number of homicide cases over the years,
00:31:46
but this case particularly stands out in my time on the homicide unit. - The court case was a particularly horrifying one.
00:31:55
The prosecutor warned the jury that they were gonna hear some horrendous details
00:32:01
and particularly, the detail that she still may be alive when she went into the water.
00:32:07
[dark tune] [dark tune] [boat whirring] [creepy music] - In May, 2015, Tomasz Kocik was charged
00:32:24
with the murder of his girlfriend, Marta Ligman. Her body had been found in the Grand Union Canal earlier
00:32:30
in the year after a boat owner spotted human hair coming out of a suitcase floating in the water.
00:32:37
[zipper zipping] The post-mortem revealed a history of domestic violence, but whilst her boyfriend admitted disposing of her body,
00:32:45
he denied murder. He claimed she had died of a drug overdose. Pathology proved that was a lie.
00:32:55
[slow piano music] Five months after his arrest, Kocik was brought before the Old Bailey in London.
00:33:06
Representing the case for the Crown Prosecution Service was Senior Prosecutor Devi Kharran.
00:33:14
- I had been working on this case for a long time to prepare the case for present it at trial.
00:33:20
A homicide prosecution requires a lot of preparation. We have to find as much evidence as possible
00:33:28
to prove every element of the offense of murder beyond reasonable doubt, to prove that Kocik was the killer of Marta.
00:33:40
It was a very intense atmosphere in the courtroom. There was a lot of press and media attention surrounding this case.
00:33:48
- I attended court when he faced trial. It was one I covered from start to finish.
00:33:55
The case of Marta was a very harrowing case, just the details of the injury she suffered.
00:34:04
The prosecutor warned the jury that they were gonna hear some horrendous details.
00:34:13
- It was very distressing for friends and family to have to come to court and listen
00:34:17
to the distressing details that were presented about Marta's life. [somber music]
00:34:27
- [Richard] The prosecution outlined the case against Kocik. - We relied on the strength of the evidence
00:34:34
to present a clear and coherent case to the jury. The evidence consisted of various strands,
00:34:40
including CCTV evidence, to prove his movements at the time of her killing, evidence of her identity card
00:34:49
that was found burnt and damaged, and the pathological evidence that gave the police the indication
00:34:58
as to how Marta's injuries were sustained. He clearly ruled out natural causes
00:35:05
as a result of her death. - [Richard] The court also heard how the obsessive and violent Kocik behaved towards Marta.
00:35:16
- We used the evidence of her friends and family who provided strong evidence of a change of demeanor in Marta.
00:35:23
Her behavior had changed. She became withdrawn, sad. She had visible facial injuries,
00:35:30
which caused her friends and her manager significant concern about Kocik' controlling
00:35:36
and coercive behavior. A man like Kocik is gonna want somebody like Marta to fall for him,
00:35:42
so he's gonna present himself, you know, as the perfect boyfriend. "You've met the one."
00:35:49
And he would use all his manipulative skills in doing that. Trouble with people like Kocik is,
00:35:58
they can do that for a while, they can't keep it up, so they have to get that commitment
00:36:04
from somebody like Marta very, very quickly because they know it's all gonna fall apart.
00:36:09
They know that their true self is gonna come out very, very quickly. Kocik is such an extreme example of a fixated,
00:36:19
obsessed, and very insecure man. He was entitled. "I own you. You're my property.
00:36:26
Don't you dare try and leave me because you will pay." - [Richard] Kocik himself decided not to take the stand,
00:36:35
but his legal team presented his version of events. - Kocik claims he returned home from work
00:36:46
to find Marta already dead. He said that he believed Marta died of a heart attack
00:36:53
and thought he would get blamed. - Anybody's who's in court is going to try and defend themselves.
00:37:03
They don't want to go to prison. And this has got a life sentence on the end of it.
00:37:09
He had to have a story for Marta being dead, so he picks another implausible story
00:37:16
that Marta was a drug addict and she had been taking drugs. Denigrating the victim and making them the bad person
00:37:24
and you the victim, that is incredibly common. - [Richard] The pathology had conclusively proved
00:37:32
drugs played no part in Marta's death. Kocik's case was falling apart. - So, his whole defense at court that he just found her dead
00:37:44
and, for some reason, decided to put her into a suitcase instead of in the paramedics,
00:37:48
I mean, it is all absolutely ridiculous. And this was not a sophisticated defense.
00:37:56
He's in a position now where he's proven to be a liar. - Kocik, while in court, he didn't show any remorse at all.
00:38:05
He was very cocky. And the sort of the lies he told were very distressing for Marta's family, claiming that, you know,
00:38:17
this had happened during rough sex and, you know, that she'd been taking drugs with him.
00:38:28
- And obviously distressing for her friends and family to see Kocik in the dock.
00:38:32
In every homicide case that we prosecute, we have the opportunity of meeting the victim's families.
00:38:38
Marta's mother did provide a victim impact statement, which was very, very sad.
00:38:46
- She was very tearful. She told how she was begging this man to help look for her
00:38:53
when, all along, he was the one who killed her. - [Richard] The text Kocik sent to Marta's friends
00:38:58
were also read out in court. - Kocik sent messages to Marta's friends to suggest that she was still alive.
00:39:10
He wanted to make it look like she'd left him. And when her mother was begging him to look for her,
00:39:20
but he pretended that she'd just run away and didn't wanna get in touch with him.
00:39:25
- Initially, the evidence from the telephones went against the prosecution case because the evidence showed that Marta's telephone was used
00:39:35
after the prosecution say her body was placed in the canal. However, at trial, that evidence
00:39:43
assisted the case for the prosecution because it proved that, in fact, her phone was being used
00:39:49
by Kocik to create a false trail for the officers. - [Richard] Kocik had proved to be a calculated controlling liar,
00:39:59
but it was Marta's body that would deliver the irrefutable evidence of her final moments.
00:40:07
The autopsy revealed that sometime between the evening of the 29th of April and the 1st of May,
00:40:13
Kocik beat Marta unconscious in a sustained attack that could have lasted minutes or hours
00:40:19
or possibly even days. When he thought she was dead, he wrapped her in curtains and bin bags
00:40:26
and stuffed her into a suitcase with her head between her knees. He then dragged the case half a mile to the canal
00:40:34
before dumping her in the water. So, how did Marta actually die? The widespread heavy bruising tells us
00:40:42
all about her last hours. A bruise is just blood leaking from damaged blood vessels,
00:40:49
but it requires pressure in the bloodstream for that leakage to occur. Marta's body was just covered in bruises,
00:40:56
and it was quite clear that this could only have happened if her heart was still beating.
00:41:05
Although she was alive when she received these injuries, it was the repetitive blunt force trauma
00:41:11
to her torso and legs that killed her. [intense foreboding music] - It's not clear exactly at what point that took place,
00:41:21
but that could have taken place while she was in the suitcase, either when Kocik was walking down
00:41:28
towards the canal or indeed after the suitcase had been placed in the canal, which clearly raises the possibility
00:41:34
that Marta was still alive at either of those points. - Some of the expert evidence showed that some
00:41:42
of the bruising on her body could have been hit by a boat while she was still alive in that suitcase.
00:41:51
He warned the jury not to think of the possibilities around that. Obviously, it's hard not to.
00:42:00
- Something happened for him to think that she was dead. I don't think that he thought
00:42:06
by putting her in a suitcase that would kill her. I think he put her in the suitcase
00:42:10
because he thought she was dead. He probably, at that point, wasn't thinking straight.
00:42:15
He just knew he needed to get rid of Marta's body. The thing is with people like Kocik,
00:42:25
they use violence routinely. They know how far to go. They absolutely do know how far to go.
00:42:31
The idea that they take it too far one day and kill someone, really, there's not a lot to support that.
00:42:37
They know when to stop. I think whatever the challenge was that came from Marta,
00:42:43
it was enough that he took it far enough to kill her, given himself permission to kill her in fact,
00:42:49
and thought that he had done exactly that. - [Richard] The jury saw through Kocik's lies.
00:42:56
That pathology was damning. After deliberating for just over a day, they rejected his defense.
00:43:03
[foreboding tune] - Tomasz Kocik was found guilty of Marta's murder. He was convicted of murder and he was sentenced
00:43:12
to 18 and a half years as a minimum sentence recommendation of his life sentence.
00:43:18
[foreboding tune] - Kocik was a very violent and dangerous man. At trial, Kocik, from my recollection, showed no remorse.
00:43:31
He maintained a very cold demeanor as he sat in the dock at the Old Bailey. After the jury had delivered their verdict,
00:43:38
we were very satisfied that we had secured justice for Marta, her family, and her friends,
00:43:47
and that is of paramount importance in any homicide case. - I think this case was a classic intimate partner homicide.
00:43:59
Very quick, very intense. In some ways, it was different because Kocik was so extreme in his control of Marta,
00:44:12
and I think everybody noticed the changes in her, so you could almost watch this playing out from a distance.
00:44:20
[mysterious music] - She'd obviously been in a very abusive relationship. He was very controlling of her.
00:44:29
And instead of breaking up with her, allowing her to go her own way, he'd brutally beaten her
00:44:36
and stuffed her into a suitcase and dumped her into a canal. Absolutely horrific.
00:44:42
- I've prosecuted a number of homicide cases over the years, but this case particularly stands out in my time
00:44:49
on the homicide unit. Marta Ligman was a young, happy, very kind, and caring young lady
00:44:58
who wanted to come to London to start a new life. The truth of what happened that night
00:45:04
was that Marta was subjected to a violent and brutal attack by the man who she loved and cared for.
00:45:17
That particular point at where Marta's body was discovered is a part of the canal in Little Venice
00:45:23
that I visit frequently. And every time I visit that point at the canal, I always stop and think about Marta.
00:45:36
- Tomasz Kocik had mentally and physically controlled Marta throughout their relationship.
00:45:41
It ended with her murder. He tried to claim that Marta had died of a drug overdose
00:45:48
and that he was innocent of her killing, but the pathologist's report made sure
00:45:53
the jury saw through his lies. Although she never spoke out in life, in death, her body was able to reveal the truth
00:46:02
about what had happened, and put Kocik behind bars. [intense dramatic music]
