48 hours is looking into the death of a Wisconsin woman who prosecutor say was poisoned with ey drops Lynn Hernan was
00:00:07
found dead in her home in 2018 by her good friend Jesse keski who told police she was helping to care for the
00:00:14
62-year-old as she struggled with a variety of health conditions but prosecutors say keski poisoned her and
00:00:21
did it for money daa Duncan reports for this week's 48 hours in October 2023 39 y- old Jesse
00:00:30
keski went on trial in a Wisconsin courtroom accused of killing her very good friend 62-year-old Lynn hearnen
00:00:39
Jesse kvy took care of Lynn during the last year of Lynn's Life Jesse was like an adopted daughter to Lynn so Jesse and
00:00:47
Lynn were very close Stephanie Rodriguez covered the trial for the CBS affiliate
00:00:53
in Milwaukee she was going to like doctor after doctor friend Anthony posa says Lynn's health problems had become
00:01:00
increasingly frustrating for her and then she'd call me and say I can't find anything wrong with me at the trial a
00:01:07
first responder testified about what she found at Lynn's home she has multiple medication bottles that are within Arms
00:01:14
Reach and this appears to be an unknown powdery substance left behind on a plate
00:01:19
I remember hearing it from Jesse on the phone looks like Lynn you know committed
00:01:25
suicide toxicology reports revealed Lynn had something very unusual in her blood
00:01:32
the medical examiner found tetrah hydraline in ly hearn's system it's the active ingredient in eye
00:01:40
drops that when ingested can be fatal prosecutors say Jesse poison Lynn for her Fortune the state argued that Linn
00:01:48
hearnen was worth more dead than alive to Jesse kvy but at trial the defense contended this was not a homicide at all
00:01:57
the defense argued that Lynn wanted to die by suicide because she was sick of being sick Lynn Lov Jesse if Lyn Hearn
00:02:06
was here today she would say are you crazy prosecution she say he's innocent and D Duncan joins us now uh D
00:02:18
thank you very much for being here so the idea is that the fortune the money was the motive how much money we talking
00:02:24
about here so according to investigators keski was able to take $144,000 before she died
00:02:32
$44,000 after so they were looking at this as someone who was taking advantage of someone who was vulnerable Someone
00:02:39
who lived alone and she did have some health complications but it really wasn't until this woman Jesse keski sort
00:02:46
of re-enters her life and she can't quite figure out why she has these other ailments and why she's feeling um sick
00:02:54
and doctors can't really point to it so of course as you heard in the piece they
00:02:59
found this very unusual high amount of tetrah hydrosaline which is what is also an active ingredient in ey drops yeah I
00:03:06
never knew that eye drops could kill kill you me neither let's just start with that I that it can make you sick I
00:03:11
I did not know that it's not either you know I just want to make sure that we're
00:03:14
not saying that they can in terms of using them in your eyes the idea was that she was using this with something
00:03:21
else that she may have been that she was drinking so what did Jesse's defense team say on her behalf so Jesse's
00:03:27
defense team in reference to that motive of money said listen the reason why you
00:03:31
saw checks written to Jesse kesy from Linn hernon is because Jesse helped to take care of her it wasn't uncommon for
00:03:38
her to write her a check for her rent or her car payment or the IRS I mean there
00:03:44
were different checks that looked as though they were written by Lyn hearnen to Jesse keski um but again in this
00:03:51
piece you'll see even though that keski did not take the stand her story continues to evolve about what she did
00:04:00
why she was where she was and what she knew in reference to Tetra hydraline wow very interesting hour yeah
00:04:07
it's very yeah D Duncan thank you very much appreciate it you can watch D's full report death by ey drops on 48
00:04:14
