A Maryland man who was working as a subcontractor at a construction site in Fairfax County, Virginia, was killed Monday morning in a work accident.

Nelson Aguilar-Salamanca, 55, was working at a construction site on Capital One Drive, in Tysons, when he was hit by some rebar that was being hoisted in the air by a crane at about 7:30 a.m., the Fairfax County police said in a statement.

Aguilar-Salamanca died from his injuries at a hospital, police said.

The medical examiner is working to determine the cause of death.

Just last week, on Christmas Eve, a construction worker was killed in a work accident at the old Fannie Mae site in Northwest D.C. He had been pinned underneath the bed of a dump truck.
