The remains found in the Hamilton sewer system last summer have been identified as those of William Lee Campbell, a 46-year-old resident who was reported missing three years ago. Investigators were able to make the identification through extensive testing and a match in the national DNA database maintained by the FBI.

Why it matters

The identification of Campbell's remains through the national DNA database highlights the importance of such databases in helping to solve missing persons cases, even years after an individual has gone missing. It also raises questions about the circumstances surrounding Campbell's death and the need for continued investigation to determine the cause and manner of his passing.

The details

Contractors performing a routine inspection on the Hamilton sewer system came upon Campbell's remains in August 2025 near Third and Market streets. The Butler County Coroner's Office sent the remains to the Ohio Bureau of Criminal Investigation for extensive testing, which ultimately led to the positive identification through a match in the national DNA database.

  • Campbell's remains were found in the Hamilton sewer system in August 2025.
