KINGSPORT, Tenn. (WJHL) — Kingsport police charged a U.S. Postal Service (USPS) mail carrier with several drug-related counts Tuesday after they allegedly witnessed him “ingesting narcotics in plain sight” inside a mail truck.

According to a Kingsport Police Department (KPD) news release, members of the KPD’s vice and narcotics unit were conducting surveillance of Joshua Honaker, 44, of Blountville, as part of a joint investigation with the federal Office of the Inspector General.
