Ricky Lamot and Christopher Serrano died after gunfire at United Rentals, leaving families and coworkers grieving as police investigate why it happened.
MANASSAS, Va. — A Northern Virginia community is mourning two fathers killed in a workplace shooting at United Rentals as investigators continue trying to determine what led a fellow employee to open fire and wound a third coworker.
Manassas police identified the men who died after the Sept. 30 shooting as Ricky Lamot, 48, and Christopher Serrano, 33. A third employee was hospitalized in stable condition and was expected to survive. The suspected gunman, United Rentals employee Marvin Grant, 37, later died from a self-inflicted gunshot wound after police located him more than 100 miles away on Interstate 81, authorities said.
The deaths quickly took on a deeply personal dimension in Manassas. Police Chief Douglas Keen said he knew Lamot through youth football and recalled his commitment to coaching young players. Keen said the loss was painful for a community already dealing with other recent violence and pointed to the impact on Lamot’s children. Local reporting identified both Lamot and Serrano as fathers.
The shooting was reported shortly after 7 a.m. at the United Rentals facility at 9415 Wellington Road. Officers arrived within minutes and found three employees suffering from gunshot wounds. Two were later pronounced dead, while the third survived. Police said several other workers were at the business when the shooting occurred.
Investigators said Grant was also an employee at the facility. Keen said Grant made a statement to another worker indicating three people were going to die before producing a handgun and opening fire. Police believe some type of altercation occurred before the shooting, but they have not said what the disagreement involved or whether it explains why the three men were targeted.
Grant left the facility before officers arrived, setting off a search that stretched across Virginia. Police used cellphone information in an effort to locate him and passed information to Virginia State Police after his phone was detected in the Harrisonburg area. A trooper later saw Grant’s vehicle traveling south on Interstate 81 in Augusta County.
State police said an attempted traffic stop at a rest area turned into a pursuit after Grant returned to his vehicle and drove away. He later pulled over near mile marker 227 and emerged with a firearm. Tactical officers and a negotiator responded to the scene. Police said Grant suffered a self-inflicted gunshot wound during the standoff and died. Troopers did not fire their weapons, state police said.
The violence also disrupted the area surrounding the Manassas workplace. Roads near Wellington Road were restricted as police searched for Grant, and nearby schools took safety precautions. Students from Jennie Dean Elementary School were redirected to Metz Middle School while the response continued. Those measures were lifted after authorities determined Grant had left the region.
United Rentals said it was devastated by the deaths and injury and was providing support to workers affected by the shooting. The company also began reviewing the incident internally, according to published reports. The Manassas facility was closed in the immediate aftermath as investigators and employees dealt with the consequences of the attack.
Despite the end of the search for Grant, police have said major questions remain. Investigators have not announced a motive and continue examining what happened before the shooting. For the families of Lamot and Serrano and the coworkers who survived the attack, the investigation now proceeds alongside a period of mourning for two men whose deaths have reverberated beyond their workplace.
