OKLAHOMA CITY (AP) -- Oklahoma County authorities believe live videos posted on Facebook depict an Oklahoma man wanted in the killing of two relatives, the shooting of two police officers and numerous carjackings.

Oklahoma County Sheriff's Office spokesman Mark Opgrande says investigators believe the videos may have been posted Sunday night by 38-year-old Michael Vance after a shootout with police in Wellston, about 35 miles northeast of Oklahoma City.

In one video, a man in a shirt that appears to be covered in blood says he's about to steal a vehicle and it's "gonna be intense."

In a second video, the same man shows a long gun on the passenger seat of what appears to be another vehicle and says: "Letting y'all know, look, this is real."

Vance is a suspect in the shooting of two Wellston police officers Sunday night and in a double slaying in Oklahoma County.

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