TUCSON, Ariz. (AP) - The Arizona Department of Corrections has begun to search for an independent party to investigate the execution of a convicted murderer who took nearly two hours to die.
The department has put out a request for proposals for an independent review of the July 23 execution of Joseph Rudolph Wood, whose prolonged death made international headlines.
The department says in a news release that Wood was given 750 milligrams each of midazolam, a sedative, and hydromorphone, a painkiller. Officials have not previously said what dosage of drugs he was given.
Wood was sentenced to death in 1991 for the murders of his ex-girlfriend, Debbie Dietz, and her father, Gene Dietz, in Tucson two years earlier.
His attorneys say the execution was botched. The department says Wood did not suffer.
