Manassas shooting: 2 victims dead, suspect dies of self-inflicted gunshot wound, police say

MANASSAS, Va. - Two victims of a northern Virginia workplace shooting died Wednesday, while the suspect died of a self-inflicted gunshot wound following a police pursuit, according to authorities.

What we know:

Virginia State Police troopers spotted the suspect, 37-year-old Marvin Grant, driving southbound on Interstate 81 near mile marker 235 in Augusta County following the shooting at a United Rentals facility in Manassas.

Grant pulled into a rest area at mile marker 232, where troopers attempted a traffic stop. He exited his vehicle briefly, got back in, and continued driving southbound on I-81, initiating a police pursuit.

Grant pulled over again near mile marker 227 and exited the vehicle with a firearm pointed at his head. A Virginia State Police tactical team and negotiator responded to the scene.

At approximately 10:30 a.m., police say Grant suffered a self-inflicted gunshot wound. He was taken to an area hospital, where he was pronounced dead. State police confirmed officers did not use force during the incident.

During an afternoon news conference, Manassas City Police Chief Douglas Keen announced that two of the victims allegedly shot by Grant had died from their injuries at local hospitals. They were identified as Richard Lamot, 48, and Christopher Serrano, 33.

Lamot was a regional manager at United Rentals from Fauquier County.

The backstory:

Earlier in the morning, Keen said officers responded to the facility on Wellington Road at around 7 a.m. following multiple calls reporting an active shooter at the workplace. Responding officers found three victims, all employees of the facility. Two victims were found in a garage area, while a third walked in an office area in the garage.

Police said a handgun was used in the shooting.

Lamot and Serrano were pronounced dead at Prince William Hospital. A third victim is in stable condition at Inova Fairfax Hospital, according to police. 

Investigators said Grant was a coworker with a North Carolina address. Authorities believe an altercation at the site led to the shooting, though police are still reviewing video evidence and have not determined the exact number of shots fired. 

"What we do know at this point is that Mr. Grant came to work this morning, made a statement to a coworker that three people are going to die. He then produced a handgun and began shooting," Keen said. "What we don't know is a motive. That brings no relief to our victims' families. We have to figure out what happened here. What caused this? While some may consider the case closed with the death of Mr. Grant, that brings no closure to the case. Our community is still hurting. The family of United Rentals is still hurting. The families of the victims are still hurting."

Keen noted that police had no prior interactions with Grant before Wednesday's incident.

Numerous other employees were on site at the time of the shooting. Area schools were placed on lockdown as a precaution. 

The investigation is ongoing.
