WBRZ - Baton Rouge

The St. Bernard Parish coroner says a heart problem may have killed a 63-year-old Mississippi man whose body was found near his boat on Nov. 14.

Dr. Bryan Bertucci says a preliminary autopsy found that David McAdory of Madison did not drown. The parish released his findings Saturday.

McAdory was reported missing when he failed to return home from a trip. He had left Madison on Nov. 12.

Louisiana Wildlife and Fisheries agents found his body submerged near his 19-foot boat, which was near an oil rig off Martin's Island in Chandeleur Sound. His wallet was on the boat.
