Inside the mind of Mark Twitchell, "the Dexter killer"
CBSN
When investigative journalist and MacEwan University Professor Steve Lillebuen set out to write a book about the Dexter-obsessed murderer Mark Twitchell in late 2010, the last thing he expected was to get a jailhouse call from the killer himself.
"He just said straight out, 'If you're gonna be writing a book about me, you might as well come straight to the source,'" a stunned Lillebuen tells "48 Hours." That call set in motion a correspondence with the would-be serial killer that lasted for almost three years. Now, "48 Hours" contributor Troy Roberts reports on those letters and gets a revealing look at what one retired FBI criminal profiler believes motivated Mark Twitchell "The Dexter Killer" airs Saturday, April 23, at 10/9c on CBS and streaming on Paramount+.
"He wrote me probably 30 or 35 different letters — up to about 350 pages ... like an entire book worth" Lillebuen, the author of "The Devil's Cinema: The Untold Story Behind Mark Twitchell's Kill Room" tells "48 Hours." "He's very self-aware, and he has this sort of this obsessive-compulsive nature to want to write everything down ... I'd ask him one question … and I'd get 10 pages back as an answer."
