(The Center Square) -Dr. Robert Quinn did not personally know Tony Carruthers, the Tennessee inmate whose execution was called off in May after an attempt, but he's been to Tennessee's Death Row. Hines' attorneys cite Carruthers' failed execution in their petition for clemency for their client. Regardless of how doctors feel about the death penalty, the American Medical Association's policy cautions physicians from participating in executions. The doctor involved in Tony Carruthers' attempted execution in May is facing a medical malpractice complaint filed by Carruthers' sister. He gave Carruthers a one-year reprieve after Carruthers' failed execution.
