PITTSBURG COUNTY, Oklahoma - The Oklahoma Highway Patrol says a McAlester man drowned while trying to retrieve his boat on Lake Eufaula Wednesday evening.

Troopers identified the man as 66-year-old James Cosper.

According to the OHP, Cosper was loading his boat at a ramp when the boat started to drift away.  A witness saw Cosper jumped off a nearby boat dock and begin to swim toward the boat.  The witness told troopers, the victim began to struggle, then went underwater and never resurfaced.
