An Illinois man has died following a tubing accident on Lake Michigan despite what the Berrien County Sheriff’s Department describes as “gallant efforts” to save him. 66-year-old Robert Amenitsch of Niles, Illinois was on a tube being towed at a slow speed by his son, Michael, of Stevensville. Police say the man rolled on his back and then into the water about two miles north of the piers in St. Joseph. His son turned the boat around immediately, and found his father unresponsive. He was taken to the beach with the help of good Samaritans for CPR and then to the U.S. Coast Guard station by the USCG vessel, where he was pronounced dead. The incident happened in a “no wake” zone of the lake north of Rocky Gap County Park just after 3:30 Sunday afternoon. Police are still investigating.
