The Clark patch had a little more info. Seems they found him in waist deep water. He might have gotten stressed out by the whole ordeal and had a heart attack. Tough break, rip.

"He has been identified as Ronald Moore, 69, of Union.Moore was fishing in the surf at the Sandy Hook fishing beach before 8 a.m. Wednesday when his gear got carried out in a wave. He tried to retrieve it and that's when he, too, got pulled out into the rough surf. The currents around Sandy Hook, a peninsula, can be very strong.
Another fisherman saw the man getting pulled out into the icy ocean water and called 911. Rangers with the National Park Service responded, as did Middletown police and Sea Bright Fire Rescue. When they got there, Moore was in waist-deep water and he was pulled from the water by park rangers, and Sea Bright personnel performed CPR.
