HAMMOND, Okla. (KFSM) -- A gunman who has been on the run for at least a week may have been sighted by law enforcement.
Oklahoma Highway Patrol Captain Paul Timmons posted on Twitter, "Have law enforcement in the area of Hammond, OK, possible sighting Michael Vance."
Another Twitter post by a non-law enforcement person mentions, "found his camp site ... car also seen ... we are locked and loaded."
Police say, Vance, 38, killed two people and injured four others, including two police officers, in Oklahoma.
The Chandler, Oklahoma resident is believed to be carrying an AK-47 and driving a silver 2007 Mitsubishi Eclipse sedan.
Vance is accused of two counts of first-degree murder, possession of a firearm after a former felony conviction and unauthorized use of a motor vehicle.
Emergency officials in Lincoln County, east of Oklahoma City, say Vance shot and wounded two officers from the town of Wellston about 7 p.m. local time last Sunday (Oct. 23) after they had responded to a disturbance call.
During the initial questioning of Vance and another man, Tony Heavner, the officers were struck by gunfire, according to court records.
One officer was shot in the foot and the second was shot in the leg, County Sheriff Charles Dougherty said.
The wounded officers returned fire, striking Vance at least twice, Dougherty said.
Heavner was arrested, but Vance fled the scene in a patrol car.
Vance then posted a video on Facebook Live, stating he was in pain.
In the video there appears to be blood on his pink T-shirt.
Vance also said in the video that he was about to steal another car.
Vance then stole a Lincoln Town Car from a woman at a nearby mobile park and then shot at her, according to CNN affiliate KOCO.
The woman was injured but not taken to the hospital, KOCO said.
