A Pike County man is dead following a swimming accident Saturday night at Patoka Lake in Orange County. State Conservation Officers say 43-year-old Anthony Catt of Otwell apparently struck his head on the side of a pontoon boat while diving into the water and failed to resurface. They located Catt’s body about six-hours later with an underwater camera. An autopsy is scheduled for Monday. Conservation officers say Catt was not wearing a lifejacket and that alcohol is believed to have been a contributing factor.
