(Eaton, OH)--A traffic stop in Eaton turned up 49 caps of heroin, and now a Richmond man is in the Preble County Jail. 24-year-old Robert Sigmon was stopped on North Barron Street. The officer observed marijuana in plain view, and that led to a further search. That’s when the heroin was discovered. Sigmon told officers that he had just purchased the drugs in Dayton and was on his way back to Richmond.
