Death row inmate refuses last meal after losing final attempt to halt execution for crime she committed at the age of 18

A Tennessee death row inmate refused a last meal after losing a last-ditch effort to halt her execution for a gruesome murder she committed at the age of 18. 

Christa Gail Pike, 50, is scheduled to be put to death by lethal injection on Wednesday morning for the 1995 slaying of 19-year-old Colleen Slemmer in a fit of jealous rage.

She is now refusing a last meal, according to the Tennessee Department of Correction, after Tennessee Governor Bill Lee denied her clemency request and the US Supreme Court declined to stay the execution.

Supreme Court justices made the decision less than one day before the deadline, with no explanation for their decision, The Hill reports.

Meanwhile, Governor Lee said he decided not to intervene in the case 'after deliberate consideration of Christa Gail Pike's request for clemency and after a thorough review of the case.'

Pike's lawyers said in the aftermath they were 'deeply saddened and heartbroken' by the governor's decision.

'Moving ahead with her execution puts the State of Tennessee on singular footing,' they said in a statement to Fox 17. 

'Christa will be the first person Tennessee executes in the modern death penalty era who was a teenager at the time of the offense, and the first woman executed by the state in more than 200 years.'

Prosecutors have said Pike, then aged 18, feared Slemmer was a romantic rival and lured her to a secluded area where she and her boyfriend, Tadaryl Shipp, tortured and killed their 19-year-old classmate.
