Christa Pike
Christa Pike, 18 years old (at the time of the crime), cut her teen rival's throat with a box knife and carved a pentagram on the dying girl's chest. She then took a piece of her skull as a souvenir.... Christa Gail Pike, aged 26, is one of only two female death row inmates at Tennessee Prison for Women in Nashville. Christa was convicted in 1996 of the murder of Colleen Slemmer. There were two more people involved in this case. Christina's boyfriend, Tadaryl Shipp and a friend Shadola Peterson I haven't been able to find out if Christa has been executed yet, but I'm still trying to find more information.
