CLEARWATER, Fla. (WFLA) – Defense attorneys for Michael Drejka, the man who was found guilty of manslaughter in the shooting death of Markeis McGlockton last year, say the 49-year-old has been transferred to protective custody and fears for his life after being attacked in prison.

“They put a lock inside a sock,” said defense attorney Bryant Camareno, “… and they apparently attacked him with that.”

“We’re all concerned, myself, Mr. Trevena, the rest of the defense team.”

Drejka is being held at Lancaster Correctional Institution in Trenton, approximately 35 miles west of Gainesville.

His attorneys say he was attacked from behind on Tuesday afternoon. Drejka told his wife he was hit in the head with a lock inside a sock, according to attorneys. His wife told attorneys he needed five stitches and is now living in fear.

The Florida Department of Corrections confirmed Drejka was “involved in an isolated incident” with another inmate around 12:30 p.m. on Tuesday. The department’s press secretary said the situation was “brought under control by institution security staff.”

“Per standard protocol, Inmate Drejka was examined by medical staff and the incident is being investigated,” the press secretary said in a statement. “At this time, Drejka is in administrative confinement separate from the general population, pending protective management review.”

According to attorneys, the alleged attacker said they knew Drejka was the man involved in the deadly shooting over a parking spot in Clearwater that made national headlines.

The shooting happened on July 19, 2018, in a parking lot. Authorities said Drejka shot and killed 28-year-old Markeis McGlockton during an argument over a handicapped parking spot.

In October, Drejka was sentenced to 20 years for that shooting.
