The search at a northern Oklahoma lake for a missing country music singer from Arkansas has been suspended for the night.

The Oklahoma Highway Patrol says it called off the search for 29-year-old Craig Strickland because of darkness.

The patrol said it used rescue dogs and boats in the search on the north end of Kaw Lake, south of the Oklahoma-Kansas state line.

Strickland is the lead singer of the Arkansas-based country-rock band Backroad Anthem. He disappeared during severe storms last Sunday while on a duck hunting trip with friend Chase Morland.

The pair’s capsized boat was found that day. Morland’s body was recovered from the lake Monday.
