RIVERTON, Wyo. (AP) — Toxicology reports show drugs and alcohol may have contributed to the drowning death of a man who was found in an irrigation ditch in Riverton.

Joseph Atkin's body was discovered Feb. 21, nearly an hour after he was reported missing.

According to the Fremont County Coroner's Office, Atkin had a blood alcohol content of .169 at the time of his death. Marijuana, amphetamine and Valium were also found in his system.

Deputy Coroner Tadd Curtin says Atkin's toxicology is relevant to his drowning.

A woman had reported seeing the Lander man standing near the edge of the water before his body was found about a mile and a half downstream. It is unknown whether he willingly entered the flood waters.
