A 27-year-old man drowned while diving for golf balls at an Irving country club Wednesday night, according to officials.

Employees at the Las Colinas Country Club noticed one of men employed by the company that recovers balls from the golf course ponds had not returned by closing time at 8 p.m, said Stephen Salzman, the club's general manager.

When they found the man's cart sitting empty next to one of the ponds, they called police, who searched the lake and recovered the body identified by the Dallas County medical examiner's office as Christopher Logan.

"I don't really know what happened," Salzman said. "The water is not that deep in that pond." He said the pond was only five feet deep in some areas. "Something catastrophic must have happened."

Irving police did not return a call made by The Dallas Morning News .
