MSNBC Presents 'Criminal Mindscape: Ron Luff'

Enter the minds of the nation’s most notorious criminals on MSNBC’s newest series, Criminal Mindscape. Each episode features intense one-on-one interviews between a forensic profiler and prisoners facing life in prison or sentenced to death row. Each interview delves deep to understand the madness that drove the serial killers, rapists and snipers to commit their heinous acts.

On April 17, 1989, Dennis and Cheryl Avery and their three young daughters were killed execution-style in a barn in Kirtland by cult leader Jeffrey Lundgren, later to be known as the Kirtland cult slayings. This Sunday, forensic psychologist N.G. Burrell sits down with Ron Luff, a member of Lundgren’s cult now serving life, to understand how conscientious, God-fearing citizens became complicit in multiple acts of murder. How can the mind be manipulated to believe mass murder is justified?
