Pike does not deny committing the killing, but her supporters argue the state should consider Pike’s age at the time, mental illness and a history of severe sexual abuse that included being raped from the time she was a toddler. Assistant Federal Defender Stephen Ferrell said Pike’s death sentence is an outlier because other 18-year-olds in Tennessee have had such sentences vacated.

After the killing, Pike was diagnosed with bipolar disorder and post-traumatic stress disorder. In her clemency petition she said she only wanted to fight Slemmer but killed her in a frenzied attack when she couldn’t “put the brakes on.”
