Joshua Gregory Harmon, 16, was reported missing from Blountville in Sullivan County, Tennessee after last being seen on July 21, 2025. On that day he was wearing a beige shirt and jeans. He is described as a white male with strawberry-blond hair, about 5 feet 7 inches and 140 pounds, with a faded neck tattoo that was being removed.

The Sullivan County Sheriff’s Office opened an investigation the day after he was last seen, and the case is listed in the National Missing and Unidentified Persons System. Few details have been released publicly about the circumstances of his disappearance, and there have been scarce official updates or media coverage.

Joshua’s disappearance has been noted alongside that of 17-year-old Wyatt Allen Wiers, who was last in contact on July 21, 2025 in Blountville. Online discussion has raised the possibility of a connection, but no public confirmation exists that the two were together or that the cases are linked. If anyone saw Joshua on or after July 21, 2025, or has information about his whereabouts, please come forward.
