MOST EVIL Debuts 12/7 on Investigation Discovery

After more than five years, the compelling series, MOST EVIL returns with new episodes and a fresh look when it premieres on Investigation Discovery on Sunday, December 7 at 10/9c to examine the minds behind the most heinous murders. In its new format, hosted by leading clinical and forensic psychologist Dr. Kris Mohandie, the series shines a klieg light on a killer's motive, method and thought process. One of the most provocative and most popular features is coming back in this new season -- the infamous scale classifying killers from impulse murderers, to those motivated by jealousy or rage, to the outright psychopathic.

"The goal of this series is to come to a better understanding of why criminals behave in the ways that they do -- ultimately attributing a numerical value to the worst offenders - thus creating a hierarchy of evil," said Henry Schleiff, Group President of Investigation Discovery, Destination American, American Heroes Channel, Discovery Family Channel and Discovery Fit & Health. "By examining the broad variety of themes and subjects including rage, delusions, manipulation, control and deception, the audience gets an extraordinary look into the deep DARK MINDS of the worst criminals to walk the earth."

Each episode of MOST EVIL looks at three cases meticulously dissected by Dr. Kris Mohandie to get to the heart of the terrifying question: what drives someone to murder? Through archive and new first-person interviews conducted by Dr. Mohandie with the killers themselves, the series will delve into the reasons - including neurological, environmental and genetic factors -- why people kill and will then place them on an official scale of criminal behavior, ranging from 1 to 22.

The premiere line-up for MOST EVIL is as follows:
