The two men and a 12 year old boy went missing after their boat capsized on Keystone Lake late Saturday night. Searchers found the boy's body, but still haven't found the two men.
Investigators say high winds played a role in the accident and as more bad weather approaches, crews have intensified their search.
News on 6 reporter Omar Villafranca says the Oklahoma Highway Patrol and the Army Corp of Engineers took to the water at daybreak Monday to search for Richard Watts and Johnny Paul Graves.
Boats scan the water's edge and the Oklahoma Highway Patrol plane looks from the sky for any signs of the two Tulsa men. The men were not wearing life jackets.
Investigators think the cold front that blew in Saturday night brought in heavy winds, strong enough to capsized their 14-foot fishing boat.
The water at Keystone Lake was calm Monday, but with 40 mile-per hour winds, it's a different picture. Travis Miller with the Army Corps of Engineers: "When you're looking at a little bass boat, something out there, you're going to have waves crashing over you. You're going to be cold and wet, it's really nasty conditions."
All the families can do now is wait. Eva Miller already lost her 12-year old grandson Lemiah Denny. She's waiting to hear the fate of Johnny Paul, a man she loved like a son. She now wants others to learn from their tragedy. Eva Miller: "I want people to know that at the 1st sign of any kind of weather change, whether you're swimming, boating or fishing; take heed, because Oklahoma weather is so unpredictable."
Richard Watts and Johnny Paul Graves were not wearing life jackets. Lemiah Denny was found with his on.
The state Medical Examiner's office told Lemiah's family that he died of hypothermia.
