Tennessee Gov. Bill Lee has halted executions for the remainder of the year after the attempted execution of Christa Pike late Wednesday, according to The Associated Press. Lee said in a statement that he has ordered a comprehensive, third-party review to determine exactly what occurred, according to the AP. The state's remaining scheduled execution this year will not take place, the AP reported. The Tennessee Department of Correction confirmed Pike is being treated at an offsite medical facility following the attempted execution. The lethal injection chemical in the protocol has consistently been effective, and the protocol does not allow for additional procedures beyond what was carried out this evening, a TDOC spokesperson said in a statement. Pike has spent more than three decades on death row following her conviction in the 1995 torture and murder of Colleen Slemmer in Knoxville. Pike was 18 at the time of the crime. Investigators said Pike bragged about the killing and showed other students a piece of Slemmer's skull. Pike's case marks the first time Tennessee has sought to execute someone for a crime committed at age 18 since the death penalty was reinstated in 1976. Lee reviewed Pike's clemency request and declined to intervene.

It remains unclear what went wrong during the attempted execution, and officials have not provided an update on Pike's condition. Pike's attorneys said she is being treated at a local hospital following the attempted execution but that they have not been informed of her condition. Tonight the State of Tennessee once again failed to carry out a lawful execution, the attorneys said in a statement. We take no pleasure in being right, but the concerns raised by Ms. Pike proved to be true: difficult vein access, blown veins, degraded pentobarbital, no emergency medical care available when things inevitably go wro #tmj4 #crimewatchmilwaukee
