A 13-year-old Ann Arbor boy is dead after drowning in Lake Michigan off South Haven on Saturday. The South Haven Police Department says its officers and South Haven Area Emergency Services were dispatched to South Beach just before 12:30 p.m. after several 911 calls about people struggling in the water. Responders arrived to learn a paddleboater had rescued one adult, but a child was still in the water. About 20 minutes later, the child was found on the shore about 100 yards south of the South Pier. CPR was performed on the boy as he was taken to Brandon Hospital South Haven, but the rescue effort was not successful and the boy was pronounced dead. The victim and his family had been visiting the area from Ann Arbor. Witnesses told police the family had been swimming, drifted away from the shore, and became exhausted. The National Weather Service forecast for the day began with a green flag advisory for all South Haven beaches, and it was updated to yellow around 11:10 a.m. as the wind changed.
