GRAND RAPIDS, MI -- A worker has died after an accident at a downtown Grand Rapids construction site.

The accident happened at about 2 p.m. Saturday, Oct. 20 near a courtyard space between 37 Ottawa NW and 50 Monroe Avenue NW.

Grand Rapids police said the man, 48 , of Grand Rapids, was struck by a large piece of timber that fell from above.

The timber was described as piece of wood about 20 feet long, 12-inches wide and 2-inches deep.

Grand Rapids firefighters responded to the scene and the man was rushed to a local hospital. But police later were notified he died from the injury.

"They don't know where the board came from," Grand Rapids police Lt. Pat Merrill said.

He was told the board struck the man in the back and shoulders.

Another worker standing close to the fatally injured man escaped any contact with the board.

Grand Rapids police were investigating the accident Saturday. Officials with the Michigan Occupational Safety and Health agency also were expected to respond to the site.

Merrill said the workers were believed to be involved in demolition at the site.

The two buildings are being renovated for a 130-room hotel and office space.

Owen-Ames-Kimball has a construction trailer at the site but the employer of the deceased worker was not known.
