Sneak peek: Death and the Dentist | Forensic Files

see emergency I'm in the parkor by Planet Fitness in Kingston I was looking for my husband and I found him in his
car and I don't know if he's breathing Thomas Coleman was dead in a vehicle in a parking lot of a Fitness
Plaza the car was sitting here yes actually this particular spot right in front of us there was nothing in the car
that would suggest anything of him being attacked or anything obvious of physical
trauma when I was told that my father died everything I had ever known changed in a
second my dad was an amazing father to four kids and a great man at first we thought it was a heart attack something
natural but sudden after the autopsy we knew something was wrong something happened to him the
doctor label it as acute maasam poisoning poisoning yes medz what is mazam it's a conscious
cative it's used in hospital settings also in dentist office who do oral surgery there was no reason for it to be
in his system is it like that that you change your mind and go this is a homicide basically yeah
we knew Kohl's had video on the corner of their building told them I need this video why you pull it up real quick
we'll take a look at it to see if there's any cars that meet him there and uh sure enough there's a car
that pulls in Parks first so he shuts the car down this is uh Tom Coleman's car pulling in right there it's 4:54
a.m. our victim Tom Coleman pulls up the side by side that was basically holy [ __ ] so
somebody had knowledge of literally speaking with our victim that morning see the white SUV here
leaving we started thinking with a circle of people close to Tom Coleman and the only person with a white SUV was
uh Gilberto Nunes they suspected Gil Nunes who was my dad's best friend who we had met who
we knew it was shocking it's emotional for you of course very emotional because Tomo was my best friend truly we had uh
Nunes come meet us for an interview I know you met with Tom at Planet Fitness early that morning no I know you were
there figure you know I wasn't there probably I said it over a 100 times I wasn't there you gave him a drug that
you have access to Mr Nunes his profession was a dentist hello I'm uh Dr Gilberto Nunes Gilberto Nunes quick
quickly became a suspect for some obvious reasons we've been following this case for about a year there have
been some new developments recently and we've learned there's more to it than meets the eye more than just a
suspicious death besides treating my patients with dignity and and doing everything I do
for them I just like to serve people not to hurt anybody you f him something that
killed him yes you did I mean I haven't done anything wrong this is a murder case without murder
