Authorities are searching Lake Superior for three boaters, including a 9-year-old and his father, who didn't return from a fishing trip.

Family members called police when the trio who departed from Michigan's Upper Peninsula didn't return for a fish fry Saturday night.

Cmdr. Carolyn Moberley of the U.S. Coast Guard said Sunday evening that the search would go on overnight. There was still no sign of the boat early Monday.

State police Sgt. Jamie Patterson says the lake may have been a bit choppy Saturday but the weather was "pretty decent."

The boy and his father are from Ishpeming. They were with a 61-year-old man from Atlantic Mine.

The search involves state police, the U.S. and Canadian coast guards and local police.
