Most Evil

Clinical and forensic psychologist Dr. Kris Mohandie, host of 'Most Evil.'

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.

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.
