Officials are investigating after an angler was found dead in his boat on the shore of Mille Lacs Lake. The Mille Lacs County sheriff’s office says 59-year-old Daniel Gable, of Hastings, was reported missing by his wife around 11 p.m. Friday. Searchers found his body Saturday morning inside his boat, where it had washed ashore near the landing. An autopsy was planned to determine the cause of death.
