BILLINGS, Mont. (AP) — Yellowstone County authorities have released the name of a 39-year-old man who died after he was hit by a falling concrete column at a construction site in Billings.

Assistant coroner Richard Hoffman said the victim was David Shepard of Billings. Hoffman said an autopsy was being performed.

Fisher Construction Inc. co-owner Brent Sumner told The Billings Gazette it wasn't clear how the horizontal concrete beam broke away from the building's exterior Tuesday morning. Sumner said it swung down and struck Shepard in the head.

The crew was working at the former Labor Temple Hall, which is being renovated as part of a low-income housing project.

The federal Occupational Safety and Health Administration office is investigating Shepard's death.

Coroner Cliff Mahoney said the death was accidental.
