DESOTO COUNTY, Miss. — A man who reportedly hit several vehicles with a concrete truck before threatening to kill everyone was shot by a Desoto County deputy Thursday morning.

The DeSoto County District Attorney confirmed 50-year-old Michael Earl Cowan was charged with aggravated assault with a deadly weapon.

It all began early Thursday morning in Tunica County when the man was involved in an accident. He fled the scene and made his way to the area of Goodman and Interstate road in Desoto County.

Once in the area, he allegedly hit several other vehicles and shouted “I’m going to kill everyone.”

He was shot by a deputy with the Desoto County Sheriff’s Office, authorities said.

Video of the incident shows deputies dragging Cowen out of the truck and arresting him.

Cowan was airlifted to the Regional Medical Center. He was treated, released and booked into the Shelby County Jail. He will be extradited back to Desoto County to face at least five aggravated assault charges.

The Horn Lake Police Department confirmed that the Mississippi Bureau of Investigation was called to handle the case.

 “I look to my left and I see the police coming down with a concrete truck on the side. Each one of them, each officer on the side of the concrete truck,” witness Christopher Scott said.

Scott, who recorded the event, said he had just dropped off supplies for his job when authorities blocked off the intersection to stop Cowen’s vehicle.

Scott said Cowen hit a white truck that then crashed into his. As soon as officer started firing, he ducked down for his own safety.

“I was not ready for this morning. oh wow,” he said.
