OKLAHOMA CITY (AP) -- The Oklahoma Department of Corrections' former director has testified again before a multi county state grand jury that is investigating problems with the state's last two scheduled executions.
The Oklahoman reports that Robert Patton testified for about 90 minutes Thursday. He first testified on Oct. 21.
The grand jury is investigating, at the request of Attorney General Scott Pruitt, how the wrong lethal injection drugs were used during an execution last January, and how the same incorrect drugs were delivered to the state prison hours before an execution was to be carried out last September.
Patton resigned in December and accepted a position as a deputy warden at a private Arizona prison.
The grand jury is expected to issue a report on the case Feb. 18.
