PHOENIX (AP) — Arizona Gov. Jan Brewer is ordering a review of the state's execution process after a condemned inmate gasped and snorted for more than an hour and a half before he died.

Brewer said in a statement Wednesday that she's concerned by how long it took for the sedative and pain killer that were injected into Joseph Rudolph Wood's veins to kill him.

The governor says she's directing the Department of Corrections to conduct a full review, but she says Wood's execution showed justice was carried out.

Brewer says medical and eyewitness accounts indicate Wood did not suffer and died in a lawful manner.

His defense lawyers say the botched execution should have taken 10 minutes and should bring new scrutiny to the death penalty in the U.S.

Wood was convicted in the 1989 shooting deaths of 29-year-old Debbie Dietz and 55-year-old Gene Dietz.
