VALLEY, Neb. (AP) — Authorities in eastern Nebraska say a man has died after being pinned by a forklift.

Valley police say George Young was using the forklift Monday night while working at Midwest Manufacturing. At some point, the machinery backed into a shelving unit and pinned him.

Co-workers freed Young and began performing CPR on him. He was sent by helicopter to a hospital and pronounced dead.

The Occupational Safety and Health Administration is conducting an investigation.
