Christa Pike was 18 when she was involved in the 1995 murder of fellow Knoxville Job Corps student Colleen Slemmer, a crime that ultimately placed her on Tennessee’s death row. Pike was convicted of first-degree murder and conspiracy to commit murder and sentenced to death in 1996. Her boyfriend, Tadaryl Shipp, was also convicted, but because he was only 17 when Slemmer was killed, he was legally too young to receive the death penalty. Instead, he received life in prison with the possibility of parole and remains incarcerated. Peterson, the third teenager involved, faced a dramatically different outcome after agreeing to testify against Pike and Shipp. She pleaded guilty to being an accessory after the fact and, under the agreement, received six years of probation rather than a prison sentence. The three defendants therefore entered the same case with very different circumstances, including their ages and Peterson’s cooperation with prosecutors.

Pike’s legal team has repeatedly pointed to those differences while challenging her execution. Her attorneys argue that Pike’s age, traumatic childhood and mental-health struggles should have received greater consideration when she was sentenced. Pike has said she now views the killing as the worst mistake of her life and has acknowledged the devastating effect it had on Slemmer’s family and others. Meanwhile, Peterson appears to have completed the probationary punishment imposed after her guilty plea, and little reliable public information is available about her present life. Shipp remains behind bars after being denied parole in 2025, with another review scheduled for 2031. Pike, now 50, remains scheduled for lethal injection on September 30, 2026, although her lawyers continue pursuing legal and clemency options in an effort to have her death sentence changed to life imprisonment.
