The Livingston Parish Coroner’s Office performed an autopsy Thursday on a man who died after a shootout with an off-duty parish deputy earlier in the week.

However, Thursday afternoon, the office announced it would hand off its findings to State Police, who had not released details from the autopsy as of 6 p.m.

Sidney Averett, 46, died following a gunfight with the deputy at a home on Country Club Lane. Multiple law enforcement sources have identified the deputy as David Johnson.

Johnson was at Country Club Lane with his girlfriend when the woman’s ex-husband arrived at the house and tried to get inside. The two men got into a gunfight, then Averett was killed. Trooper 1st Class Jared Sandifer said investigators had not confirmed the deputy killed Averett.

State Police previously had stated the shooting happened about 2 p.m. Tuesday, which is closer to the time they were notified, Sandifer clarified Thursday. He said the shooting initially was reported at about 12:30 p.m.

Sheriff Jason Ard requested the state take the lead on the Country Club Lane investigation because it involved one of his deputies, Sandifer said.

Johnson also was involved in a fatal shooting while on duty in 2011, which State Police investigated and determined to be a justifiable homicide.

According to a State Police report, the Sheriff’s Office was dispatched to a “domestic dispute” involving Jonathan Julius Clayton and his girlfriend at 30610 Corbin Ave. in Walker on April 4, 2011.

Under the subheading “Investigative Findings,” State Police reported that when Johnson arrived at the mobile home, Clayton, armed with a knife, walked toward Johnson “in a fast manner” and ignored Johnson’s commands to stop before Johnson shot and killed him.

In a statement given to parish detectives, Johnson said Clayton cut his own neck and “made comments that he wanted to be shot by police.”

Reporting Officer Ben Ballard wrote “there is no evidence that Deputy David Johnson committed any crime according to Louisiana Law and acted according to his responsibility and duties as a commissioned Livingston Parish Sheriff Deputy.”
