A 61-year-old Green Bay man is dead after falling into Mueller’s Lake in Polar Saturday afternoon. Police say the man was in a boat and the seat came loose. He fell backwards into three to four feet of water. A man with him jumped in, got him out of the water and CPR was performed. He was taken to Aspirus Langlade Hospital and then flown to Aspirus in Wausau where he died later that evening. Authorities think underlying health factors may have contributed to his death.
