ARDMORE, OK - Oklahoma Highway Patrol said they recovered the body of a Stephens County man this morning, who drowned while swimming with friends on Lake Murray.

Troopers said 31-year-old Kenneth Thomas of Duncan was swimming near Tipps Point on Lake Murray with nearly thirty people when he went missing around 11:30 a.m. Sunday.

"He was asked to go get something, I think it was a cigarette for somebody" Trooper Mike Groeber said.

Lake Murray officials said Thomas was unaccounted for for about twenty minutes.

"Somebody stepped on what they thought was a body, and it was him," Groeber said. "They had no idea that he had drowned."

Groeber said friends pulled Thomas from the water and a near by nurse attempted CPR on him until emergency personal arrived on scene.

Thomas was pronounced dead at Mercy Hospital in Ardmore.

Groeber said Thomas did have a medical history of seizures, which may have played a role in the drowning.

He said he does not believe alcohol was a factor.

"I smelled no alcohol on him when we were working on him," Groeber said. "There was some indication he had been drinking yesterday but not today."
