Tennessee Gov. Bill Lee told reporters in Knoxville on Tuesday that there will be no changes to the protocol for capital punishment in the state following the botched execution attempt of death row inmate Tony Carruthers on May 21.

In May, the Republican governor suspended Carruthers’ execution for one year after the medical team failed to find a vein when trying to set up the backup IV line of lethal drugs. They tried to set up the IV line for more than an hour.

“The Department of Corrections did exactly what they were supposed to,” Lee told reporters. “I decided to suspend the execution. I have the authority to do that. I’m the only one who can.”

“Given the circumstances of not being able to find a vein, I made that decision,” the governor added. “But the protocol itself and the process for the death penalty in this state — which is the law of Tennessee that the people have decided — but the protocol itself still stands, as it should.”

After the botched execution, eight Republican lawmakers wrote a letter to the governor, which urged him to review the death penalty protocol, according to the Tennessee Lookout. The letter called the incident a failure “to carry a lawful sentence of its own courts,” but the lawmakers still expressed support for the death penalty.

Krisanne Vaillancourt Murphy, executive director of the Catholic Mobilizing Network — a group that works with the U.S. Conference of Catholic Bishops on opposition to the death penalty — expressed disappointment in Lee’s comment in a statement to EWTN News.

“Tony Carruthers’ botched execution reminds us that every execution — regardless of the method or the procedures that take place — is a barbaric act that disregards the sanctity of life,” she said. “I am heartbroken to hear that Gov. Bill Lee has decided to let current lethal injection procedures stand.”

Murphy noted that Republican lawmakers urged the governor to commission an independent review of how the execution was botched.

“It is helpful to pause in times like this and ask ourselves: To what lengths will the state go to seek revenge?” she said. “There is nothing appropriate in this situation. The only way to avoid perpetuating more violence and harm is to step back from executing people altogether.”
