The Case of Colleen Slemmer

Colleen Slemmer, 19, was a student at the Knoxville Job Corps Center when she was lured into a remote area of the University of Tennessee's agricultural campus on January 12, 1995. She was attacked and killed by fellow students Christa Pike, Tadaryl Shipp and Shadolla Peterson. Colleen suffered prolonged beating and cutting before her death. Pike was convicted of first-degree murder and sentenced to death. She remained on Tennessee's death row for three decades.

Overview / Background
Colleen Ann Slemmer was 19 years old and a student at the Knoxville Job Corps Center in Tennessee. She had travelled to Knoxville to participate in the federal Job Corps programme, which provides education and vocational training to young people. Colleen was attending the programme alongside Christa Pike, Tadaryl Shipp and Shadolla Peterson. The four knew each other through the Job Corps centre. In the days before her death, tension developed between Colleen and Pike. Prosecutors argued that Pike believed Colleen was interested in her boyfriend, Tadaryl Shipp. On January 11, 1995, Pike told another Job Corps student that she intended to kill Colleen. The following evening, Colleen left the Job Corps centre with Pike, Shipp and Peterson. She was led to an isolated area near the University of Tennessee's agricultural campus.
Crime Scene
The group walked to a remote area of the agricultural campus on the evening of January 12, 1995. Colleen was attacked after arriving at the location. The assault lasted approximately 30 to 45 minutes. Court records established that she was repeatedly beaten and cut with a box cutter and a small meat cleaver. She was also struck in the head with a piece of asphalt or rock. A pentagram was carved into her chest while she was still alive. Colleen eventually died from the injuries she sustained during the attack. Her body was left in the wooded area. The following day, January 13, 1995, a University of Tennessee grounds employee discovered her body near the agricultural campus greenhouses. Investigators secured the area and began examining the circumstances surrounding her death. A piece of Colleen's skull was missing and was later found to have been retained by Pike.
Investigation
Police quickly identified the three Job Corps students who had accompanied Colleen into the area. Investigators interviewed Christa Pike and Tadaryl Shipp on January 14. Pike gave police a detailed account of the killing. Her statements, together with physical evidence and testimony from other Job Corps students, became important evidence in the prosecution. Investigators established that the attack had been planned rather than being a spontaneous encounter. Shadolla Peterson eventually cooperated with prosecutors. The investigation established that the three defendants had been involved in the attack, although their individual roles differed. The case attracted substantial media attention because of the brutality of Colleen's murder and the pentagram carved into her body. The circumstances also became associated with the wider Satanic Panic that had influenced public discussion of alleged occult activity during the period.
Outcome
Christa Pike was convicted of first-degree murder and conspiracy to commit first-degree murder in 1996. She was sentenced to death for Colleen's murder and received a consecutive 25-year sentence for conspiracy. Tadaryl Shipp, who was 17 at the time of the murder, was convicted and sentenced to life imprisonment with the possibility of parole. Shadolla Peterson pleaded guilty to a reduced charge and received probation after agreeing to testify against Pike. Pike's murder conviction and death sentence were subsequently upheld through multiple appeals. She remained on Tennessee's death row for approximately 30 years. An execution date of September 30, 2026 was eventually set. A last-minute federal stay was initially issued on the morning of the scheduled execution, but the U.S. Supreme Court later overturned that stay, allowing Tennessee to proceed. On the evening of September 30, Tennessee attempted to execute Pike by lethal injection. The execution failed to result in her death. Prison officials administered two doses of the execution drug, but Pike remained alive and was subsequently transported to hospital. Her legal team has sought further intervention following the failed execution. As of October 1, 2026, Colleen's murder conviction against Pike remains in place and Pike remains under a death sentence, but the September 30 execution attempt did not result in her death.
Notes
The case remained in the public eye for decades because of the brutality of Colleen's murder and Pike's unusually long time on death row. Colleen's mother, May Martinez, has continued to speak publicly about her daughter and has supported the carrying out of Pike's sentence. The location where Colleen was murdered and the evidence recovered from the scene remained central to the prosecution's case.
