PENSACOLA BEACH, Fla. (WKRG) — A police chief from Oklahoma is dead on the Gulf Coast, and one of his officers is charged in his murder.

Mannford Police Officer Michael Patrick Nealey was booked into the Escambia County Jail Monday morning on a murder charge.

Nealy is accused of killing Mannford Police Chief Lucky Miller Sunday night. The two were on the Gulf Coast to attend a conference, according to the Escambia County Sheriff’s Office.

Investigators said the two men got into a fight at the Hilton Inn on Pensacola Beach. Miller died as a result of his injuries, the sheriff’s office said.

The 2019 Southeast Public Safety Conference is being held at the hotel this week.

Miller, 44, had been the Mannford Police Chief since 2007. He leaves behind a wife and three children.

“We are heartbroken by the news,” Mannford Mayor Tyler Buttram said in a news release. “Please keep both families in your prayers as we work to move forward.”
