Gunman dead after shooting at Virginia business, killing 2 co-workers, police say

MANASSAS, Va. (AP) — A man shot three co-workers during an altercation Wednesday at a northern Virginia business, killing two of them, before killing himself during a standoff with police along an interstate highway, police said.

Marvin Grant, 37, of Charlotte, North Carolina, opened fire at an equipment rental business in Manassas, about 30 miles southwest of Washington, D.C., Manassas Police Chief Doug Keen said at a news conference.

Keen identified the two deceased workers as Richard Lamont, 48, and Christopher Serrano, 33. A third worker was in stable condition at a Fairfax hospital, the chief said.

Grant fled in a vehicle and detectives tracked his cellphone to the Harrisonburg area, Keen said. Grant then stopped on I-81 in Augusta County and killed himself during a confrontation with Virginia State Police. A state police statement said officers did not use force.

The motive for the shooting remains unclear, Keen said.
