MORROW, Ohio (AP) — The body of a construction worker has been recovered 11 hours after a trench collapsed on him at a home construction site in southwest Ohio.

Authorities have identified the man killed Thursday in the village of Morrow in Warren County as 25-year-old Zachary Hess, of Mason.

Fire officials say Hess became buried inside a trench described as between 25 and 30 feet deep after it collapsed shortly before noon.

Dozens of firefighters and other rescuers worked to dig Hess out.

The Occupational Safety and Health Administration along with the Warren County Sheriff’s Office and Coroner’s Office are investigating.
