IDAHO FALLS, Idaho — Rescuers searched on Sunday for the body of an Idaho Falls man believed to have fallen through the ice on Gem Lake and drowned.

The Bonneville County sheriff's office said the efforts to find 46-year-old David Finnegan continued through the afternoon. Authorities believe Finnegan may have fallen through the ice, perhaps while trying to rescue one of his dogs.

Finnegan was reported missing Friday night after he failed to return home after walking his dogs. Rescue Team coordinator Sgt. Karl Casperson said a cap and ear muffs found in the ice were identified as Finnegan's by his wife, Cheryl Finnegan.

Casperson said Finnegan was last seen about 4 p.m. Friday, when he left home.
