More info trickled in this week. Seems like they had been using the shortcut under the bridge for a while, but the lake was dropping. They had slowed down to 45 or so and seemed to know it was a trouble spot. Motor came loose on impact and swung around on connecting cables impacting Tim in the chest area. He was DRT, never knew what hit him. Boat driver was treated for shock, but no injuries. I feel sorry for him too. It was an accident, plain and simple. One of those things that could happen to anyone, any day.
