LINCOLN COUNTY, Okla. -- A man accused of killing two people and shooting four others -- including two Oklahoma officers -- has a medical condition and might try to spread disease, an Oklahoma Highway Patrol poster said.
Around 6:30 p.m. Sunday, officers were called to reports of shots fired in the small area of Wellston, outside Oklahoma City.
Officials said when authorities arrived, Michael Vance opened fire with an AK-47, injuring two police officers.
The officers, identified as Shaun Stewart and Jim Hampton, suffered nonlife-threatening injuries.
After the shooting, Vance allegedly stole a Wellston police vehicle and left the scene.
While inside the vehicle, Vance went live on his personal Facebook page, saying he was going to steal another car and it was “going to be intense.”
Vance later posted another video that shows him inside a different car.
After ditching the stolen police vehicle, Vance allegedly shot and carjacked a woman. She also suffered nonlife-threatening injuries.
That woman's car was reportedly found where two of Vance's relatives were found shot to death just before midnight.
Around 10:45 a.m., authorities found the bodies of 55-year-old Ronald Wilkson and 54-year-old Kay Wilkson. Vance is the Wilksons' nephew, officials say.
According to court documents, Ronald Wilkson was shot with an AK-47. He also reportedly had a large cut on his neck that officials said is consistent with an attempt to sever his head.
Kay Wilkson suffered similar injuries, authorities said. She also had a large cut on her shoulder area. Police believe Vance attempted to remove her arm.
Vance then allegedly stole the Wilksons' silver 2007 Mitsubishi Eclipse with an Oklahoma license plate 943-LQQ.
Vance is driving the silver Mitsubishi Eclipse or a 2014 white Chevrolet Sonic with the Oklahoma plate 327-LIH, authorities told KFOR.
It is unclear how Vance would have obtained the Chevrolet Sonic.
Around 2:30 a.m., a man was reportedly shot at a gas station in Sayre, Okla. The shooting suspect matches Vance's description.
Police said the suspect attempted to carjack another victim, but was unsuccessful.
The 54-year-old man injured in the shooting was transported to a local hospital where he underwent surgery. He is currently in good condition.
Authorities are still searching for Vance.
They believe he might have returned to Oklahoma County or Lincoln County.
There is an arrest warrant out of Oklahoma County for Vance, who is wanted on two counts of first-degree murder, unauthorized use of a motor vehicle and being in possession of firearm with prior felony conviction.
According to a wanted poster, Vance has a medical condition and might try to spread a disease.
Vance is considered armed and dangerous. Police say Vance has been shot at least twice.
He was recently released from jail after being arrested for sexually assaulting a child.
