Webb's wife, Ada, says he died of a heart attack. She says the former preacher injured his knee in March and then stayed in his power recliner at home 70 miles west of Columbia. She says she cleaned the chair daily.
Deputies say Webb had sores on his body and a "very bad odor."
Webb's wife says he didn't want help because he was ready to go to heaven and see Jesus. She says he weighed closer to 500 pounds.
