Authorities are searching Monday for a man accused of shooting two police officers and suspected of killing his aunt and uncle in the Oklahoma City area.
Mark Opgrande, an Oklahoma County Sheriff's Office spokesman, said 38-year-old Michael Vance remains missing Monday morning.
Vance is suspected of shooting two police officers in Wellston, near Oklahoma City, before making his getaway in a patrol car Sunday evening. The sheriff's office says the officers are recovering from their injuries.

Authorities believed Vance then stole another vehicle from a woman before killing his aunt and uncle. The woman in the carjacking, though shot, was expected to recover from her injuries.
Opgrande said officers discovered the bodies of Vance's relatives at a mobile home in Luther Sunday night as they searched for Vance.
Vance is believed to be armed with an AK-47 and wounded from the exchange of gunfire in Wellston, NBC News reported.
The Oklahoma Highway Patrol said Vance may be driving a silver 2007 Mitsubishi Eclipse with an Oklahoma license plate of 943LQQ. Vance is described as Native American, standing 5 feet, 11 inches tall and weighing 212 pounds.
Opgrande said Vance also faces a felony charge of child sexual abuse in Lincoln County filed in July.
Vance may have been set off by a child sexual assault investigation that investigators were conducting, the Lincoln County Sheriff told NBC affiliate KFOR.
"We were doing an investigation, we arrested him. That is supposedly what set him off but we don't know that for sure yet," Sheriff Charlie Dougherty said.
No further information was released.
