Tennessee's sole female death row inmate, Christa Pike, is set to be the first woman executed in the state in more than 200 years. Her execution is scheduled for September 30, 2026 - more than 30 years after authorities said Pike, then 18, violently killed 19-year-old Colleen Slemmer, according to the Death Penalty Information Center. On Thursday, March 19, the state responded to a lawsuit Pike filed in January, in which Pike argued that the state's execution method - lethal injection - goes against her constitutional and religious rights, USA Today reported.
