for the first time on television 48 hours is revealing letters written by the so-called dexter killer police say
00:00:06
mark twitchell was fascinated with the fictional serial killer on the popular tv series dexter twitchell himself was
00:00:13
convicted in 2011 and while in prison he wrote dozens of detailed letters to an investigative journalist
00:00:20
48 hours contributor troy roberts spoke with that reporter and got a look at those letters
00:00:26
mark twitchell was an aspiring filmmaker husband and father when in 2008 he posed
00:00:32
as a woman on a dating website and lord johnny altinger a random stranger to a garage where he killed him
00:00:40
he was just a typical local guy who had dreams of making it big in hollywood action and really no red flags no
00:00:48
warning signs that something like this was on the horizon steve lillibun is an investigative
00:00:55
journalist and an author lil buen was stunned when he heard from mark twitchell as he began working on a book
00:01:01
about the case he wrote me probably 350 pages of letters the fact is society in general has a
00:01:09
deep and profound fascination with the dark side of human nature twitchell's fascination with the dark side seemed to
00:01:15
focus around the character dexter morgan from the showtime series mark twitchell
00:01:21
wrote to me quite extensively about his interest in dexter nobody would side with dexter morgan if you went around
00:01:27
slaughtering school teachers and mail carriers on a whim there's significant links to dexter
00:01:34
twitchell had a kill room set up with plastic sheeting he had a table set up for his victims he had
00:01:40
this kind of processing kit that was very similar to what dexter uses he's a depraved individual and he knows
00:01:46
that retired fbi criminal profiler julia kelly reviewed mark twitchell's writings
00:01:52
for 48 hours she thinks she knows what made twitchell tick i think he identified with dexter to
00:02:00
some degree i think he's different than dexter he's not killing bad guys he's killing very innocent good people living
00:02:07
productive lives cali believes twitchell took pleasure in planning and executing his crimes as if
00:02:14
they were romantic trysts he's targeting men that perhaps he would be interested in having a date with
00:02:23
it's a combination of a sexual motive and a thrill killing in 2023 twitchell will be eligible to
00:02:30
apply for early parole experts say it's a long shot mark twitchell cannot be rehabilitated this
00:02:38
is who he is and troy roberts is with us troy good morning wow this really is a look inside
00:02:43
the mind of a killer 350 letters and twitchell might be paroled is that true well uh he's going to apply um stranger
00:02:52
things have happened i can't imagine that they would grant him parole he hasn't expressed any remorse
00:02:59
for what he has done [Music] you know what was so remarkable about about this story is that he's
00:03:05
unremarkable an average guy he's kind of decent looking affable intelligent he's a
00:03:14
a husband a father and a guy you would chat to at a bar not knowing he harbors these sick
00:03:22
fantasies so you know looks can be deceiving you didn't meet him but the investigative reporter you spoke with
00:03:28
did what was her what was her impression that his impression was what i just just said i mean normal manipulative
00:03:36
uh charming guy um trying to win you over um uh but no hint of the dark side and
00:03:45
that's scary because you know you don't you know he's not frothing at the mouth his eyes
00:03:51
aren't spinning in his head right but and uh but he was able to do just so much harm there's no signs
