Authorities searching for suspect in Oklahoma killings

OKLAHOMA CITY -- Authorities have been hunting for nearly two days for an Oklahoma man they say posted live videos to social media while running from police during a violent rampage that included shooting two police officers, armed car thefts and killing his aunt and uncle, apparently attempting to cut off their heads.

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

The FBI is coordinating the search for Vance among several federal, state and local agencies and is being tight-lipped about the information released so Vance isn't tipped to their efforts, spokesman Terry Weber said in a statement.

"This investigation is ongoing and any premature release of information regarding the apprehension efforts of Mr. Vance can negatively impact these efforts to safely apprehend (him)," Weber said.

The two police officers were shot and wounded as they responded to shots fired Sunday evening and exchanged gunfire with Vance in Wellston, about 35 miles northeast of Oklahoma City. The Lincoln County Sheriff's Office said one person was arrested, but Vance fled in a patrol vehicle. The officers' injuries weren't life-threatening, and both are expected to recover, said Oklahoma State Bureau of Investigation spokeswoman Jessica Brown.

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

Ronald Everett Wilkson, 55, had been shot and had 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 neck wounds, along with defensive wounds on her arms, the affidavit stated.

The Oklahoma Highway Patrol said Vance is believed to be driving a silver 2007 Mitsubishi Eclipse with an Oklahoma license plate of 943LQQ.
