Autopsy results say a 94-year-old man found dead in a central Indiana lake one day after leaving an assisted living center drowned and had a heart problem. Madison County Coroner Marian Dunnichay tells The Herald Bulletin that Richard D. Hunt died of drowning and had a ruptured left coronary artery. She says it’s unclear whether the rupture happened before or after Hunt fell into the water. Toxicology tests are pending.
