LUTHER - Authorities say a man accused of shooting two police officers also is suspected of killing his aunt and uncle in the Oklahoma City area.

Oklahoma County Sheriff's Office spokesman Mark Opgrande says 38-year-old Michael Vance remains missing Monday morning.

Vance is suspected in the shooting of two police officers in Wellston near Oklahoma City, then making his getaway in a patrol car. Opgrande says authorities believe he then stole another vehicle from a woman whose condition has not been released, then killed his aunt and uncle. Opgrande says officers discovered their bodies at a mobile home in Luther Sunday night as they searched for Vance.

Opgrande says Vance also is facing a felony charge of child sexual abuse in Lincoln County that was filed in July.
