The death of Joel Daniel Poston, 57, has been ruled an accident, according to Florence County Coroner Keith von Lutcken.
Poston's body was found in a ditch in January.
"Upon receipt and review of toxicological analysis, autopsy and other tests results on Mr. Poston, the manner of death is best deemed accident. The results of the toxicological analysis indicate Mr. Poston had several components in his system that contributed to his death, thus resulting in the cause. Through our investigation, there is no evidence that foul play is involved," Lutcken released Monday.
Poston had been missing for more than a month when his body was found.
