The crime took place on July 4, 1982. Nadean was an LPN in a nursing home that I worked in when I was younger. She was also the girlfriend of my best friend's brother at the time of the crime. All my interactions with her were perfectly ordinary. There was never any indication that she was 'slow' or had below average intelligence. She seemed no different than many women that I knew. She was friendly, funny, no indication of anything sinister, BUT after the murder I heard lots of stories about Nadean when she was younger. Supposedly when she was younger, she ran around with some pretty rough girls and they enjoyed bullying others in some pretty horrific ways - hence her nickname, Mean Nadean.
Her son, Greg, was involved in a lot of drug activity. Cindy, the victim, was a beautiful girl but was unfortunately involved with some pretty unsavory characters around town.
