This episode covers the disappearance and murder of Tina Bigger, a 23-year-old psychology student from Oakland University. Key topics include her secret life as a high-priced escort, her tumultuous relationship with boyfriend Todd Nurnberger, and the investigation that led to the arrest of Ken Tranchita.

Tina Bigger was reported missing in August 1995 after her boyfriend Todd returned home to find her gone. Todd's initial report to police raised suspicions due to the couple's on-again, off-again relationship and Tina's plans to move out. Police discovered evidence of Tina's secret life as an escort, which complicated the investigation.

As the investigation progressed, police focused on Ken Tranchita, a man Tina had been seeing through the escort service. Tranchita's conflicting statements and the discovery of blood in Tina's car shifted the case towards homicide. Despite initial lack of evidence, a search led to the discovery of Tina's body in a wooded area.

Ken Tranchita was arrested and later confessed to killing Tina during an argument over money. His plea bargain resulted in a second-degree murder conviction. The episode highlights the dangers faced by individuals in the escort industry and the tragic consequences of deception.

Tina's story serves as a cautionary tale about the risks associated with leading a double life and the potential for violence in dangerous situations.

TLDR

Tina Bigger, a college student, was murdered after her secret life as an escort led to a deadly confrontation with Ken Tranchita.

00:00:14
was reported missing she had been working on a research project studying the health risks of
00:00:20
high-priced call girls in detroit but she soon discovered that prostitutes face more than health risks in their job
00:00:32
they face the possibility of violence [Music] [Applause] [Music] [Applause] [Music]
00:01:03
tina bigger was a 23 year old psychology major about to enter her senior year at
00:01:09
oakland university outside of detroit she was raised in a military family and friends knew her as vivacious and hard
00:01:18
working tina bigger was the all-american girl she came from a coast guard family her
00:01:25
father was a coast guard commander her mother was a registered nurse the people who knew tina and who were closest to
00:01:32
her knew her as a very fun-loving dedicated student well-liked by all her peers and
00:01:38
colleagues and very much be loved by her family a great big sister a great daughter
00:01:44
tina worked her way through school as a waitress at the rochester chop house and lived with her boyfriend todd
00:01:51
nurnberger in an upscale apartment complex not far from school todd nurenberger was a student at the
00:01:59
university of michigan the two had an on-again off-again relationship and friends weren't sure
00:02:06
whether it would work out tina also had another side to her she could be distrustful she could be
00:02:15
vengeful she had a temper at times too this was a tina that not a lot of people who knew
00:02:21
her saw tina was conducting a research project for school entitled a survey of sexual history and health
00:02:29
practices among women employed as escorts she wanted to find out if high-priced coal girls and street prostitutes had
00:02:38
the same knowledge of sexually transmitted diseases she decided that she wanted to do her
00:02:47
own study she thought it would help her get into a good graduate school and she decided to study high class call girls
00:02:54
and their awareness of aids and then she was going to compare the two on august 23rd 1995
00:03:03
todd left for work he said tina was still asleep when he left when he returned home that night
00:03:11
she was gone todd immediately phoned police usually missing persons the case is wrapped up within
00:03:20
a couple days maybe even a couple of hours usually phone calls could be made to determine where the person is or where
00:03:27
they've been even but from the start this case was different tina's car was gone
00:03:35
none of her personal belongings were missing from the apartment none of tina's friends had seen or heard
00:03:42
from her and police also discovered that tina was planning to move into her own apartment
00:03:48
without todd the fact that tina was looking to move to another apartment was actually in the process of
00:03:57
looking to get into another apartment led me to think that there was something wrong
00:04:04
that maybe i need to talk to todd a little bit further about what was happening in their lives
00:04:10
maybe that there was something i was missing [Music] police learned that tina found evidence
00:04:20
that todd was seeing another woman [Music] and in an unexpected twist police discovered that tina was hiding
00:04:38
some secrets of her own 23 year old psychology student tina bigger was a hard-working honor student who
00:04:51
friends say had a promising career ahead of her she disappeared without a trace shortly
00:04:57
before the fall semester at oakland university outside of detroit when her boyfriend todd nurnberger
00:05:04
called police to report her missing police were naturally suspicious the two had an on-again off-again
00:05:11
relationship [Music] a few months earlier tina found a suggestive greeting card to
00:05:18
todd from another woman and realized that todd had been unfaithful people had seen them fight sometimes he
00:05:26
was very devoted but sometimes they had a very combustible relationship he spent
00:05:31
more time with her than anyone else he probably knew her better than anyone else he would seem like a natural
00:05:37
suspect despite their differences todd nurenberger denied any involvement in tina's disappearance
00:05:45
tina worked as a waitress at the rochester chop house did tina bigger show up for work last
00:05:51
night when todd called to see if she had reported to work he was told that tina had quit her job
00:05:59
four months earlier okay thank you tina said nothing about quitting her waitressing job and had continued to
00:06:08
launder her waitressing outfits as if nothing had changed todd searched their apartment looking
00:06:17
for some clue as to where tina might have gone [Music] todd found a duffel bag he had never
00:06:26
seen before inside were condoms thigh high stockings lingerie sexual lubricants credit card slips and
00:06:43
envelopes addressed to the la escort service with the name crystal in the upper left hand corner
00:06:58
hello do you have a girl that works for your name tina bigger the owners of the la escort service said
00:07:05
they didn't know anyone by the name of tina bigger but they said that crystal was the name
00:07:11
of one of their more popular escorts escort services operate in most large cities and offer female companionship
00:07:21
demand in return for fees ranging from 150 to 300 per hour among the services provided is usually
00:07:30
sex todd now began to suspect that tina had been living a secret life as a high-priced call girl
00:07:50
she decided she was going to do a study of high class call girls and their awareness of aids and she began
00:07:57
contacting services asking if she could talk to girls she started doing that and
00:08:02
i think in the process became sort of enamored with what they were doing i think in part it was the money she was
00:08:11
broke she had maxed out her credit cards she needed a new car she had to pay for
00:08:16
school the money they make is a lot more than you make working at a steakhouse at
00:08:22
one point she was making 250 dollars for an appointment maybe women have a little
00:08:27
fantasy about themselves maybe all women do and maybe she lived it out i think she had a fantasy about herself
00:08:35
i think she wanted more attention in kind of a distant way and being a call girl she was getting it because that's
00:08:41
the kind of attention you get maybe it gave her power hi i'm crystal after initially denying it the escort
00:08:56
service eventually admitted what todd already suspected that tina beggar worked as an escort
00:09:02
with the professional name of crystal they also revealed that tina worked for two other escort services and had dozens
00:09:14
of clients that also meant dozens of possible suspects [Music] the investigation into tina bigger's
00:09:30
disappearance revealed a dark secret for the past year tina had been working as a high-priced
00:09:38
call girl it was probably very important for tina to keep this information or what was
00:09:43
going on her life away from her boyfriend because she was living with him he knew so much about her
00:09:52
but at the same time if if he had determined that she was involved with an escort service actually working for one
00:09:59
obviously that would have caused a great deal of havoc in his life and their lives together
00:10:04
he naturally was despondent at one point he even uh considered killing himself with a gun that he had but he called
00:10:13
some friends they talked him out of it and he decided basically that he was going to do whatever needed to be done
00:10:19
that he owed it to tina to get to the bottom of what had happened to her records from the escort service revealed
00:10:26
numerous requests for tina's services from a man named ken tranchita their first meeting took place at the
00:10:39
bluebird motel just 12 days before tina's disappearance among tina's personal items found in her
00:10:47
apartment was a love letter from ken dear tina my heart is yours for you to keep
00:10:54
your love will lift me off my feet you came to me your love so willing i know it's worth all our waiting
00:11:01
love can when police entered ken tranchita's apartment they noticed the name crystal on some
00:11:11
artwork attached to his refrigerator a local car dealer said tina was with ken tranchita looking at new cars
00:11:23
together [Music] you like it yeah [Applause] and that ken had offered to loan her
00:11:31
money for the car i love it ken tranchita was a 42 year old ex-convict with a history of passing bad
00:11:41
checks forgery fraud embezzlement and theft he was not the wealthy businessman he
00:11:49
portrayed to tina sort of a drifter a loner he was a petty thief and a petty con man
00:11:59
type of a person he held down some menial jobs but not for very long i thought he was just like kind of a
00:12:08
little weasel really i don't know how else you would describe him he had kind
00:12:13
of a little voice and he he was sort of pathetic really he just was a guy who probably
00:12:20
thought tina was going to be his girlfriend or something tranchita admitted meeting tina bigger
00:12:27
whom he first knew as crystal through the escort service he said they later met without the
00:12:33
agency knowing and the tina stopped charging him for their sexual liaisons since the two had become friends
00:12:43
he told police that he had driven tina to the airport just one week earlier for a flight to ohio where she was going to
00:12:50
service a client a check of flight log showed no record of tina bigger on any flight
00:13:00
to ohio ken said tina left her car with him for safekeeping while she was away when police asked to inspect the car
00:13:09
tranchita willingly obliged inside police found names and addresses of more escort service clients along with
00:13:20
directions to their homes we had learned through paperwork found in her car and through the escort service that she
00:13:28
actually had contact with people that were living out of the country they were living out of state
00:13:33
so it was possible that she could have just taken off gone someplace although the trunk was filled with
00:13:39
debris a preliminary search found no evidence of foul play research shows that most first-time
00:13:48
killers dispose of their victims bodies in locations the killer is familiar with
00:13:54
so police used cadaver dogs to search areas near tranchita's home michigan state trooper richard hetu
00:14:02
works with kai a veteran cadaver dog trained specifically to find human bodies to train the dogs the troopers hide a
00:14:12
small sample of human tissue or fluid in their wooded training area the dog isn't
00:14:18
rewarded for finding animal remains but they're rewarded for finding human remains
00:14:24
so they're going to dig along a lot harder and look a lot harder because they're working for that reward
00:14:29
trooper hitu and kai searched wooded areas around ken tranchita's rented home as well as the
00:14:36
grounds of a nearby monastery where tranchita often walked although they searched hundreds of
00:14:43
wooded acres they found nothing with no evidence to hold ken tranchita he was released from police custody
00:14:53
it was a mistake police would soon regret after police questioned ken tranchita about the disappearance of tina bigger
00:15:07
he was released because of a lack of evidence even though they suspected he knew more
00:15:13
about her whereabouts than he had told them it was clear that ken's relationship with tina was
00:15:20
more than just business since a love letter from ken was found in tina's belongings and ken had
00:15:27
promised to loan tina the money for a new car was he going to help her get a car he
00:15:33
made promises he was probably telling her things to maybe make her hang on to him maybe
00:15:40
she was making him think that they were friends just to kind of get some of these things taken care of
00:15:45
with no other leads police decided to take a second look inside tina's car to their embarrassment what they first
00:15:55
thought were coffee stains on the side of a cup now appeared to be blood and when they peeled back the trunk
00:16:03
carpet they found a pool of blood on the right hand side dna tests revealed the blood belonged
00:16:12
to tina baker the investigation was already being looked at as a homicide more so than
00:16:18
perhaps another case might have been but once they found that blood there was really no question
00:16:23
the amount of blood in the trunk pointed to murder and since the car had been in ken
00:16:28
tranchita's possession since tina's disappearance he was the prime suspect
00:16:34
but by this time ken tranchita had vanished police finally got a break in the case
00:16:42
one month after tina bigger disappeared ken tranchita's brother suggested that
00:16:48
police search a deserted home once owned by his aunt the home was just 10 miles from
00:16:54
tinabigger's apartment in the woods in the backyard police found the badly decomposed body
00:17:04
of a young woman since there were no pools of blood near the body this told forensic scientists that the
00:17:12
murder had taken place somewhere else an analysis of dental records later revealed the body was that
00:17:21
of tina bigger since the decomposition started in the neck area the coroner suspected tina had
00:17:29
been strangled since decomposition begins in the areas where there is bleeding at the time of
00:17:35
death it was a unnatural cause of death there was no fracture anywhere even in the
00:17:41
head area so neck has to be a place where the event happened and we call it a neck trauma i could not
00:17:49
identify specific if neck was slashed she was strangled she was smothered i cannot say that but it has to be a neck
00:17:57
injury and that was the conclusion a nationwide manhunt for ken tranchita was now underway
00:18:04
tranchita was eventually spotted in a run-down neighborhood in downtown detroit police closed in
00:18:12
ken made a weak attempt at slitting his wrists in the bathroom before giving himself up
00:18:18
after several hours of police interrogation ken tranchita finally admitted that he and tina had an argument over
00:18:27
money you don't have the money to loan me do you of course i have the money i
00:18:31
don't believe you the money is coming they had struggled and tina fell hitting
00:18:36
her head and died [Music] but x-rays of tina's skull contradicted that scenario
00:18:48
she did not have any skull fracture anyway if she bleed inside of the skull i would
00:18:53
have seen some blood staining inside of the skull which was not present although tina may have suffered a head
00:19:00
wound as evidenced by the blood found in tina's trunk the wound was probably not fatal
00:19:07
when tranchita was confronted with this information his statement shot police what he said was tina
00:19:16
was just so miserable in those last days that i made a sudden decision to end it
00:19:21
for her and put her out of her misery the minute the police heard that statement they thought
00:19:27
holy jesus i thought guilty of your honor ken tranchita accepted a plea bargain and pled guilty to second degree murder
00:19:38
tina's family reluctant to have tina's double life made public agreed to the deal
00:19:46
prosecutors believe when tina discovered ken had lied to her about having the money to buy the new car
00:19:53
the two fought tina struck her head and was later strangled or smothered to death
00:20:04
ken placed tina's body in the trunk of her car then dumped the body in the woods near his aunt's home
00:20:11
[Music] it was a tragic end to an unfortunate story ken tranchita was sentenced to life in
00:20:22
prison ironically while tina was living a life of deception she too was deceived by ken tranchita
00:20:33
a con man offering the promise of a big loan if tina was brought into this double
00:20:40
life under some kind of illusion that it was going to be like a scene from pretty
00:20:45
woman and richard gere was going to come rescue her and you know bring her wonderful gifts and she was going to
00:20:51
fall into this opulent lifestyle that that's not the reality of the call girl world
00:20:57
you can meet up with some very desperate characters and some very bizarre characters
00:21:02
in this case unfortunately the person that she met up with was not richard gere it was ken
00:21:07
and [Music] where tina ended up lying in that field is more the reality than the movie i
00:21:15
think she [Music] chose to cross the line and she paid the ultimate price which is
00:21:28
what all of us as parents guard against and fear the most i think for our children
00:21:34
and i believe by telling tina baker's story that we sent a message to other girls who might be in the
00:21:41
business to other young women who might be thinking of going into the business to young women who might think they can
00:21:49
tease or play a little bit with a world that they don't belong in i think that sends a message that you're
00:21:55
asking for trouble that you could end up in a situation that you can't handle that you can end
00:22:00
up dead [Music] [Music] you
