With the gunman dead, what can police establish about why three coworkers were attacked—and what is known about the worker who survived? The search following the September 30, 2026, shooting at United Rentals in Manassas, Virginia, has ended. The answers that matter to the people left behind have not.
Police said Marvin Grant, 37, shot three coworkers at the equipment-rental business that morning. Two died: Ricky Lamot, 48, and Christopher Serrano, 33. A third remained hospitalized and had not been publicly identified in the available September 30 accounts. Grant subsequently died from a self-inflicted gunshot wound after authorities located him on Interstate 81 in Augusta County. No verified motive has emerged. 1 2 14
Key facts
The workplace was United Rentals at 9415 Wellington Road, not United Rents, as an initial description called it. Lamot’s surname also needs correcting: NBC’s initial briefing account used Lamont, a spelling repeated by WENG. Potomac Local’s account of a joint Manassas City Police–Virginia State Police release identifies him as Lamot, as does Prince William Times. Those accounts support the spelling used here. 1 2 17 18
These are not incidental distinctions. Getting a victim’s name right is part of establishing who was lost. Establishing why he and his coworkers were attacked is a separate task, and the reported warning before the gunfire does not accomplish it.
A warning without an established motive
According to Chief Douglas Keen’s briefing account carried by NBC News, Grant told a coworker that three people were going to die, then produced a handgun and shot three coworkers. That is the reported warning in paraphrase, not a verified word-for-word quotation. Three people were threatened; two coworkers ultimately died and one survived. 1
The warning provides an account of what immediately preceded the shooting, but it does not establish an underlying grievance or how Grant selected the people he shot. An Associated Press report carried by The Independent describes an altercation, without explaining its nature. The fact that Grant worked with the victims is not, by itself, evidence of a particular motive. 14
Multiple active-shooter calls brought officers to the business. WTOP reports Keen’s account that officers responded at about 7 a.m. That is an approximate response time, not a precise time for the first shot. Grant was identified as being from Charlotte, North Carolina. 15 10
An early police description said he might be driving a gray Toyota Camry or Toyota Corolla with temporary North Carolina registration tags. The two possible models made that a provisional description, not a definitive identification of the vehicle. 27
NBC’s briefing account also said Grant changed vehicle tags between midnight and that morning. The available follow-up reporting does not independently corroborate the timing, provide the earlier and later registration numbers or explain the change. It would be unwarranted to turn that detail into proof of advance planning. 1
What the highway accounts establish
Police said they used Grant’s cellphone number to obtain his location while he traveled southbound on Interstate 81. Virginia State Police located him in Augusta County. Northern Virginia Daily associates approximately 8:20 a.m. with State Police receiving a lookout alert; that time does not establish when cellphone tracking began, when Grant was stopped or when he died. 1 10 12
The descriptions of the encounter are not detailed enough to reconstruct it. NBC’s initial account describes a traffic stop. InsideNoVa reports a police chase, attributing its account to State Police, while the AP report carried by The Independent describes a standoff along the interstate. All support Grant’s death from a self-inflicted gunshot wound, but they do not establish the full sequence between pursuit, stopping and confrontation. 1 13 14
No exact exit, mile marker or time of death is established in the available accounts. Nor do they establish whether any officer fired a weapon. The reported cause of Grant’s death answers one question; it does not answer that separate question about police gunfire.
The survivor is still the uncertainty
The clearest unresolved consequence is the surviving worker’s condition. NBC News and NBC4’s September 30 reporting describe that coworker as critical. Potomac Local reports a stable condition, attributing it to police, and NewsNation separately attributes a stable-condition description to Keen. These accounts cannot responsibly be compressed into a claim that the worker improved. 3 11 2 8
The Washington Post’s early September 30 account, displayed at 12:28 p.m. EDT, described all three victims as critically injured. That was an earlier snapshot, superseded on the death toll by the subsequent confirmation that two had died. Potomac Local displayed a 2:36 p.m. update with the stable description, but the available excerpt does not establish its timezone or the time of the underlying medical assessment. Publication times are not patient-assessment times. 19 2
The evidence does not resolve whether the survivor’s differing descriptions reflect a clinical change, different uses of medical terminology or a reporting error. The defensible account is narrower: one coworker survived and remained hospitalized. Neither recovery nor readiness to leave the hospital has been established.
There is also an unresolved hospital difference for the two men who died. NBC News’s September 30 briefing account names Fairfax Hospital. Prince William Times’s September 30 report says Lamot and Serrano were taken to Prince William Hospital and died there. The release-attributed reporting confirms their deaths without settling that difference. No documented transfer between the hospitals is available, and a transfer cannot be invented to make the accounts agree. 1 17 2
This account rests on police briefings and release-based reporting, not an independently examined forensic reconstruction. The complete police-release text is not available here to settle the hospital discrepancy or the highway chronology. Those limits do not weaken the established toll; they mark the boundary between what is known and what still needs explaining.
Grant’s death ended the immediate manhunt. It did not establish why Lamot and Serrano were killed, why a third coworker was shot, or what recovery will require for that survivor. An ended search is not a completed explanation.

As aired 12 lines
- A United Rentals employee shot three coworkers, killing two. The attacker later died from a self-inflicted gunshot wound, ending the manhunt, while one worker remained hospitalized. Why were these coworkers attacked, and what is known about the worker who survived?
- The shooting happened on the morning of September 30, 2026, at 9415 Wellington Road in Manassas, Virginia. Marvin Grant, 37, of Charlotte, North Carolina, was a coworker of the three people he shot. His death on Interstate 81 in Augusta County ended the search, but it did not establish a motive or resolve the surviving worker’s prognosis.
- Ricky Lamot, 48, and Christopher Serrano, 33, were the two men killed. Lamot’s surname is spelled L-A-M-O-T, not Lamont. The employer’s name is United Rentals, not United Rents. Both corrections matter to identifying the people and workplace involved. The surviving coworker’s name had not been publicly released in the September 30 accounts.
- Grant allegedly warned a coworker immediately before the gunfire that three people were going to die, then produced a handgun and shot three coworkers. That warning is not a verified word-for-word quotation. Three people were threatened; two coworkers died, and one survived. The warning does not explain why Grant attacked them or establish how he selected the people he shot. The nature of a possible altercation, and any underlying grievance, remain unknown.
- Multiple active-shooter calls brought officers to the workplace at about seven in the morning. That is an approximate response time, not an established time for the first shot. A State Police lookout alert followed at approximately eight twenty. That later time marks the alert alone: it does not establish when cellphone tracking began, when a vehicle was stopped, or when Grant died. Neither time supports a minute-by-minute reconstruction of the attack and search.
- The initial vehicle description allowed two possibilities: a gray Toyota Camry or Toyota Corolla with temporary North Carolina registration tags. It was not a definitive identification of the car. An alleged change of vehicle tags between midnight and that morning has not been independently confirmed. The earlier and later registration numbers, the reason for a change, and its timing are not established. A tag change cannot be treated as proof that the shooting was planned in advance.
- Authorities used Grant’s cellphone number to obtain his location while he traveled southbound on Interstate 81. Virginia State Police located him in Augusta County, away from the workplace attack in Manassas. The county and interstate are established; the exact stopping point, exit, and mile marker are not. Nor is the time of his death established.
- Grant died from a self-inflicted gunshot wound. Whether the highway encounter unfolded as a pursuit followed by a traffic stop and standoff, or in another sequence, remains unresolved. It is also unknown whether any officer fired a weapon. The established cause of Grant’s death does not answer that separate question.
- Lamot and Serrano died from their injuries, but their hospital destination remains unresolved between Fairfax Hospital and Prince William Hospital. There is no documented transfer between those hospitals. A transfer cannot be assumed to reconcile the difference, and the hospital uncertainty does not change the established loss of two workers.
- One coworker survived and remained hospitalized, but the descriptions of that worker’s condition differ between critical and stable. Early descriptions placed all three victims in critical condition, including one published at twelve twenty-eight p.m. Eastern Daylight Time. A stable-condition description carried a two thirty-six p.m. update, but its timezone and the time of the medical assessment are not established. Publication times are not patient-assessment times. The difference does not establish an improvement, a change in terminology, or an error. Neither recovery nor readiness to leave the hospital has been established.
- For Lamot, a youth-football coaching role and a personal connection to a local sheriff remain uncorroborated. No team, coaching organization, sheriff’s name, or exact statement has been verified. Serrano’s life outside the workplace is also not established.
- The reason these coworkers were attacked remains unknown. The surviving worker remained hospitalized, with identity and prognosis undisclosed. No independently examined forensic reconstruction or complete police-release text is available to resolve the hospital difference or the full highway chronology. Grant’s death ended the immediate manhunt; no verified motive has emerged.
