Starkweather died in the electric chair at age 20 and their story went on to inspire the 1994 thriller Natural Born Killers. The horrifying acts also inspired the book Pro Bono: The 18-Year Defense of Caril Ann Fugate by Jeff McArthur.

In an exclusive clip for the upcoming series, McArthur tells the eerie scenario of how a hypnotized Caril was led to believe by Charles that they were on a mission to save her family, but once the duo were captured by police, she was horrified to find out her parents and baby sister had actually been dead the whole time. Fugate was shocked to then be informed by authorities that she was being charged with murder.
