A construction worker was killed at a shuttered hospital in Brockton, Massachusetts, on Tuesday, officials said.
The 63-year-old man was leveling gravel when a Bobcat construction vehicle fell on him about 12:06 p.m., Plymouth County District Attorney Tim Cruz said.
The man was pronounced dead at the scene; Cruz said he had "very significant injuries. He was identified as Roger Porter, from East Sandwich.
Federal, state and local investigators, including the U.S. Occupational Safety and Health Administration, or OSHA, were looking into what led to the death, Cruz said.

Aerial footage from above the scene showed several fire vehicles and fire officials meeting with construction crews.
Porter wasn't driving the Bobcat when the incident took place — "leveling out gravel as it was being put into a pit and there was an accident," Cruz told reporters.
Construction was delayed amid the investigation. The company doing the work is LMA Services Stoughton, according to Cruz.
A major fire at Brockton Hospital has closed the facility since February.
