Christa Pike-In 1995, 18-year-old Christa Pike lured out her fellow Job Corps trainee, 19-year-old Colleen Slemmer, to an isolated section of the University of Tennessee agricultural campus, spurred on by the belief that Slemmer was trying to steal her boyfriend, Tadaryl Shipp. Pike bashed her head with a chunk of asphalt and kept a piece of the skull as a souvenir.
