McALESTER, Okla. (AP) -- Convicted killer Eric Allen Patton is executed at the Oklahoma State Penitentiary, becoming the third Oklahoma inmate put to death this year.
Oklahoma Corrections Department spokesman Jerry Massie says the 49-year-old Patton was pronounced dead at 6:10 pm Tuesday.
Earlier in the day, the US Supreme Court rejected an emergency application, filed by Patton's attorneys, for a stay of execution.
Patton was convicted of the December 16, 1994, murder of Charlene Kauer during a robbery at her Oklahoma City home.
During Patton's execution, state corrections officials planned to use a slightly different lethal drug recipe for the first time.
The new system -- in part a response to a challenge filed by Patton -- was to deliver a larger dose of anesthesia before the fatal drugs were administered.
Patton's last meal Tuesday afternoon was a large pepperoni pizza with sausage and extra mushrooms and a large grape soda.
