OKLAHOMA CITY (AP) -- Authorities have spent more than 24 hours seeking a man they say posted live videos to social media while running from police during a violent crime spree that included shooting two police officers, armed car thefts and killing his aunt and uncle.

Michael Dale Vance Jr., a 38-year-old from Chandler, Oklahoma, is wanted on multiple charges, including two counts of first-degree murder. Police say he was last seen early Monday about 30 miles from the Texas border in western Oklahoma - 165 miles away from where the manhunt began Sunday night in Wellston.

The two police officers responded to shots fired Sunday about 35 miles northeast of Oklahoma City, where they were shot and suffered injuries that were not life-threatening. One person was arrested, the Lincoln County Sheriff's Office said, but Vance fled in a patrol vehicle.

Vance is suspected of later shooting a woman and stealing her vehicle at a mobile home park near Wellston, then driving about 8 miles to the mobile home of his aunt and uncle in Luther and killing them, Oklahoma County Sheriff's Office spokesman Mark Opgrande said.

The body of Ronald Everett Wilkson, 55, had a bullet wound and stab wounds to his neck "consistent with an attempt to sever his head," Oklahoma County Sheriff's Deputy Michael Belanger wrote in an arrest affidavit. Valerie Kay Wilkson, 54, had similar wounds to her neck along with defensive wounds on her arms, the affidavit stated.

Investigators found a large knife covered in blood inside the home, along with a blood-stained shirt that Vance appeared to be wearing when he apparently filmed two Facebook Live videos before going to the Wilksons' home. Authorities also found two shell casings from a round typically fired from an AK-47-style assault rifle.

In one video, a man wearing a backward baseball cap and a shirt that appears to be covered in blood says he's about to steal another vehicle and that it's "gonna be intense." In another, which seems to be filmed inside a second vehicle, the same man says: "Letting y'all know, look, this is real," before panning to a long gun on the passenger seat.

He said: "If you want to know what's up next, stay tuned to your local news."

Vance also is suspected of shooting a man in the leg at a convenience store in an attempted carjacking early Monday morning in Sayre, about 30 miles from the Texas border. Sayre Police Chief Ronnie Harrold said the man identified Vance as the man who shot him.
