An exhaustive, statewide manhunt for the 38-year-old Oklahoma man wanted for murdering his aunt and uncle and shooting and injuring three others — including two police officers — has entered its second day, with authorities telling PEOPLE they’re no closer to apprehending him.

Investigators confirm Michael Dale Vance logged onto Facebook as he was fleeing police, and began broadcasting his getaway live.

In one of the videos, which has since been removed from his Facebook account, Vance — donning a backwards baseball cap and a blood-stained shirt, and driving a truck — speaks to his viewers moments before stealing another vehicle. He tells the camera the carjacking is “gonna be intense.”

In a second clip, which appears to have been filmed from inside a different vehicle and was also taken offline, Vance shows off his gun, which is believed to be an AK-47. “Letting y’all know, look, this is real,” he says, turning the camera towards the gun, which he’d placed on the car’s passenger seat. “That’s the real deal. This s—t ain’t a joke, this ain’t a prank. I’m going f—ing live.”

Before the clip ends, Vance tells his viewers that “if you want to know what’s up next, stay tuned to your local news.”

In the videos, Vance claims he was “setup” but doesn’t say by who. He speaks of an unidentified woman he insists “knew I would flip out…that’s why she was worried about me getting out of jail.”

At one point, Vance’s phone starts ringing. He announces that the call is from his sister but says out loud he won’t be answering it: “It’s too late now,” he says into the camera.

Investigators are unsure of Vance’s exact whereabouts but believe he may be headed west in a silver Mitsubishi Eclipse, a spokesman for the Oklahoma County Sheriff’s Office in Oklahoma tells PEOPLE. Vance was last seen early Monday morning in Sayre, Oklahoma, where he allegedly shot and injured a woman during a carjacking. The woman, the spokesman says, is expected to recover.

Vance is considered armed “and very dangerous,” and he apparently has an unspecified disease police fear he may try to spread while on the lam.

The police spokesman tells PEOPLE authorities have no idea if Vance is even still alive, noting he’d been shot twice in the torso during an exchange with officers in Wellston. In the videos, Vance appears to be bleeding from his left shoulder.

Vance allegedly fired on two unidentified police officers on Sunday as he was passing through Wellston, according to the spokesman. The officers were responding to reports of gunfire and were shot at as they arrived on the scene.

Those two officers sustained gunshot wounds that aren’t considered life-threatening, and Vance allegedly fled in a patrol car before later allegedly switching vehicles in Monday’s carjacking.

According to affidavits obtained by PEOPLE, investigators suspect Vance was behind the murders of two people in a mobile home park — his uncle, Ronald Everett Wilkson, 55, and his 54-year-old aunt, Valerie Kay Wilkson. Their bullet-riddle bodies were discovered Sunday afternoon with stab wounds to the neck, indicating he tried to decapitate them. Detectives believe Vance filmed the Facebook Live videos as he was driving to their home to commit the murders.

Police recovered a large knife from the scene as well as Vance’s blood-soaked shirt.

Vance is described as Native American, standing 5 feet 11 inches tall and weighing 212 pounds.

Vance was arrested three months ago and charged with child sexual abuse, according to a police spokesman. Court records do not indicate whether Vance ever entered a plea or retained an attorney in that case.
