Morgan Bledsoe, who lives on the northwest corner of 12th Street and St. Louis Avenue, said she was doing her hair when she heard a single gunshot.

“I came out and just saw a man lying on the ground, dead,” Bledsoe said. “I had a neighbor tell me they heard a security guard yell, ‘Put it down! Put it down!’

“Then they just shot him.”

A gun that looked to be semiautomatic was found at the scene and was collected as evidence, Walker said.

He noted that the security guard had the same authority for using lethal force that a police officer would have.

Walker said shortly after the shooting that he didn’t yet know whether any vehicles had been broken into.

The names of the security guard and the deceased man were not released Friday night.

A hospital spokeswoman referred inquiries about the shooting to the Tulsa Police Department.

The guard was being questioned by detectives Friday evening.

The Tulsa Police Department is investigating the shooting, and the District Attorney’s Office will determine whether it was justified.
