Tennessee Governor Bill Lee has declined to grant clemency to Christa Pike, the sole woman on the state's death row, clearing the way for her execution by lethal injection on 30 September. "After deliberate consideration of Christa Gail Pike's request for clemency, and after a thorough review of the case, I am upholding the sentence of the State of Tennessee and do not plan to intervene," Lee said in a statement. If the execution proceeds, Pike, now 50, will be the first woman put to death in Tennessee in more than 200 years — and only the 19th woman executed in the United States since the 1970s, compared to more than 1,600 men.

Pike was 18 years old when, in January 1995, she and her then-boyfriend Tadaryl Shipp beat, tortured and murdered Colleen Slemmer, a 19-year-old they had met at a job training camp for troubled teens in Knoxville, Tennessee. The killing drew intense media attention when Slemmer's body was found with a pentagram carved into her chest. Pike claimed Slemmer had insulted her and tried to steal her boyfriend; fellow camp residents later testified that Pike had bragged about the killing and shown them a piece of Slemmer's skull. Convicted of first-degree murder in 1996, Pike was sentenced to death, while Shipp — who was 17 at the time — received a life sentence with the possibility of parole.

Pike's legal team had filed a 226-page clemency petition arguing her death sentence should be commuted to life in prison. Her lawyers contend she would not receive a death sentence today for a crime committed at 18, pointing to evolving scientific and legal understanding of adolescent brain development. "An 18-year-old brain is not an adult brain, and 18 is too young to face execution," they said. Central to their case is a documented history of severe childhood trauma — including repeated sexual abuse by multiple men from before she started school — that they argue was never properly presented to the jury at trial. Pike was diagnosed with bipolar disorder and PTSD during her imprisonment; forensic psychologists working on her defence say untreated manic episodes and post-traumatic stress significantly affected her behaviour at the time of the crime. UN human rights experts have also called for the execution to be halted.

Courts have so far rejected these arguments. Tennessee's Supreme Court ruled last year that Pike had not demonstrated sufficient grounds for commuting her sentence, and a federal appeals court found that the jury had already heard testimony about her difficult childhood, and that newer psychiatric evidence would not have changed the verdict. The Tennessee Supreme Court also denied her request this week to halt the execution. Lee has never previously granted clemency in a death penalty case.

For Colleen Slemmer's mother, May Martinez, the execution cannot come soon enough. "She did the crime. I think she should pay for it," Martinez has said, adding that she wants her daughter to "finally be resting." The victims' rights group Justice Coalition has raised funds to bring Martinez to Tennessee to witness the execution. Pike's friends and advocates, meanwhile, describe a woman transformed by decades of imprisonment and paint a more complicated portrait of justice. Pike has requested that an all-female team carry out her execution, saying being restrained by men would worsen her trauma — a request the state has said it will try to accommodate, without guaranteeing it.
