A Carbon Monoxide leak has been blamed for the death of a 66-year old Saint Charles man on Lake of the Ozarks. The Missouri Highway Patrol reports that the incident occurred on a 2003 Cabin Cruiser at the 15.5 Big Niangua Arm of the Lake at Tonka Springs Cove. Steven J. Sutton was pronounced dead at the scene. Several others on the boat also reported carbon monoxide poisoning, but only one of those received treatment; 45-year old Brian A. Long was transported to Lake Regional Hospital. No other details are available.
