ONONDAGA, N.Y. -- A worker was killed Tuesday at a nursing home when an elevator descended and pinned him while he was working on another elevator, the New York State Police said.

Troopers responded about 9:07 a.m. to the Iroquois Nursing Home, at 4600 Southwood Heights Drive, in the town of Onondaga, to help emergency responders with a person pinned in an elevator shaft.

State police said 53-year-old Christopher J. Hamelinck was killed while working at the nursing home.

Hamelinck, who was employed by Otis Elevator Company, was at the nursing home Tuesday to do service work on an elevator. While he was in the shaft doing maintenance, another elevator from an upper floor came down and pinned Hamelinck between an affixed steel ladder and a support beam, state police said.

The reason the upper elevator descended is not known, state police said, but incident was "consistent of an accidental death, with no signs of foul play."

The Occupational Safety and Health Administration responded to the nursing home and is investigating. State police said they are also continuing to investigate.
