OSHA is investigating a construction accident Wednesday evening in Cleveland, Ohio that claimed the life of a 65-year-old worker.

News sources said crews were demolishing a three-story building when the accident occurred. The victim was operating an excavating and other workers were dismantling an elevator shaft when parts of the building fell on the excavator, crushing the man.

A Cleveland police spokeswoman said the incident happened about 5 p.m. at a vacant industrial building in the city’s Buckeye-Woodhill neighborhood.

The worker’s identity has not yet been released, although he was reportedly a resident of Youngstown, Ohio.
