A boating accident at the 20 mile mark of the Lake of the Ozarks sends two people to the hospital. The Missouri Highway Patrol says on Thursday evening, 12-year old Lily Trammell of St. Joseph was swimming and tried to get into a boat while it was in gear. 44-year old David Trammell of St. Joseph jumped from the boat to help her and both of them were hit by the boat’s propeller. David Trammell was seriously injured and Lily Trammell had moderate injuries. Both were taken to a Lake area hospital for treatment.
