SUE OGROCKI/AP File Photo OKLAHOMA CITY ‚Äď The director of the Oklahoma Department of Corrections will resign from his position effective Jan. 31, marking the second departure of a high-profile figure amid a pending investigation into a series of execution mix-ups in the state, a DOC spokesman announced Friday. Spokesman Alex Gerszewski said in a news release that Robert Patton has accepted another job in Arizona, where he worked before becoming the Oklahoma DOC director, to be closer to family. Patton will begin his accrued leave time on Christmas Day, Gerszewski said. Patton joins Oklahoma State Penitentiary Warden Anita Trammell, who announced her resignation Oct. 29, in leaving before the completion of an inquiry led by the Oklahoma Attorney General's Office into the DOC's handling of the Jan. 15 execution of Charles Warner and the events leading to Richard Glossip receiving a stay of execution via an executive order from Gov. Mary Fallin Sept. 30.
