PHOENIX (AP) — State prosecutors are asking the Arizona Supreme Court to order the execution of a man sentenced to death for killing his estranged girlfriend and her father in Pima County nearly a quarter-century ago.

The Attorney General’s Office on Tuesday asked for a warrant scheduling the execution of 55-year-old Joseph Rudolph Wood III for the 1989 killings of Debra and Eugene Dietz.

Appeals courts have upheld Wood’s convictions and death sentence and the Attorney General’s Office says Wood has exhausted his appeals and has no action pending in any court.

A defense lawyer for Wood, assistant public defender Dale Baich (bache), says the Department of Corrections‘ recent decision to use a two-drug combination for executions is “novel and highly untested.”
