Investigators connected separate clues from surveillance footage, social media, a vehicle and firearms testing before a jury convicted Ja’Quan Green.
GAMBRILLS, Md. — A black 2001 Cadillac Catera, a handgun seized during an unrelated arrest, a matching vehicle decal and clothing seen on social media became the core of the evidence that led to a first-degree murder conviction in the 2022 killing of McDonald’s employee Britrain Marcelus Gray. More than four years after the shooting, Anne Arundel County Circuit Judge Elizabeth Morris sentenced Ja’Quan Dontremique Green, 25, to life in prison plus 20 years on Sept. 23, 2026.
The case against Green was built in stages rather than around a publicly identified eyewitness. Surveillance footage first gave detectives the outline of the attack. Investigators then compared the recorded vehicle and the shooter’s clothing with items associated with Green. A July 2022 arrest in Prince George’s County produced the car and handgun that prosecutors said strengthened those comparisons. Firearms testing later linked the seized weapon to shell casings found outside the drive-thru window. A jury accepted that combined evidence in January and convicted Green of first-degree murder and use of a firearm in a crime of violence.
The investigation began at about 4:45 a.m. May 13, 2022, when Anne Arundel County police were sent to the McDonald’s at 1130 Crain Highway South in Gambrills for a report of gunfire. Officers found Gray, 23, of Odenton, inside the cash booth area. He had been shot while working the overnight shift and was pronounced dead at the restaurant. Three other employees were inside and were not physically harmed. The Office of the Chief Medical Examiner performed an autopsy the following day and ruled that Gray died from a gunshot wound and that his death was a homicide.
Video from the restaurant became one of the first major pieces of evidence. Prosecutors said cameras showed a black sedan with no tag and blacked-out windows driving around the exterior of the McDonald’s. The car stopped, and a person stepped out, approached the drive-thru window and fired three shots from a 9mm handgun at close range while Gray was working inside. The shooter then ran back to the vehicle and left. Police said during the initial investigation that they believed Gray had been targeted and that the shooting did not appear to pose an ongoing threat to the broader public.
Detectives also focused on details visible in the footage that could be compared with a suspect later. Authorities said the shooter wore a dark jacket with a fur-lined hood, boots with fur trim and gloves bearing writing. Investigators reviewed Green’s social media activity and said it showed him with clothing resembling those items, a car resembling the suspect vehicle and a firearm with an appearance similar to the weapon seen in the investigation. When police later executed a search warrant at Green’s residence, they recovered boots, gloves and a jacket from his bedroom that prosecutors described as similar to the clothing in the surveillance material.
The vehicle evidence took on added importance after Green’s July 7, 2022, arrest in Prince George’s County on an unrelated criminal matter. He was driving a black Cadillac Catera from the 2001 model year. Prosecutors said Maryland motor vehicle records showed that the model was rare. Investigators also noticed a decal on Green’s Cadillac and said it corresponded with one visible on the sedan recorded outside the McDonald’s. The vehicle comparison gave the state another way to connect Green to the scene without relying on a single identifying feature from the surveillance video.
The arrest also supplied the evidence that prosecutors described as the most important forensic link. Green had a handgun with him when he was taken into custody, and officers seized it. The Prince George’s County Police Department’s Firearms Examination Unit examined the weapon. Prosecutors said testing concluded that the handgun was consistent with having fired the three 9mm shell casings recovered outside the drive-thru window. The state later presented the firearm evidence alongside the surveillance footage, the vehicle comparison and the clothing evidence to argue that the separate clues all pointed to Green.
Anne Arundel County police publicly identified Green as a suspect in Gray’s killing in July 2022, roughly two months after the shooting. The case did not reach a jury until January 2026. During a seven-day trial, prosecutors presented the evidence developed across the investigation, including the car, the gun and the recorded images. On Jan. 21, jurors found Green guilty of first-degree murder and use of a firearm in a crime of violence. The verdict established criminal responsibility even though prosecutors still lacked a clear explanation for why Gray had been selected as the target.
That unresolved question became especially visible at sentencing. Assistant State’s Attorney Glen Neubauer said there might have been no meaningful motive or that the reason was extraordinarily slight. He told the court that Gray may have appeared in a social media video created by a relative that mocked someone Green knew or the neighborhood where Green lived. Prosecutors did not present that possibility as a settled motive. Gray’s older brother, Charles Blackeney, said Gray and Green did not know each other, underscoring how little the public record explains about what prompted the killing.
Green continued to deny committing the crime after the conviction. When he spoke at sentencing, he said he did not want to diminish the loss experienced by Gray’s relatives, but he would not accept responsibility for the shooting. His attorney, Michele Vignola, asked Morris to leave open the possibility of parole and described hardships Green faced while growing up, including homelessness and exposure to violence. Green was 20 at the time of the killing. The defense argued that a sentence permanently foreclosing release would leave no room for change over the course of his life.
Morris sentenced Green to life plus 20 years but did not impose life without parole. The judge said the possibility of parole would give Green a chance to try to earn redemption in the future. The ruling did not shorten the sentence announced in court, and it did not alter the jury’s convictions. It did mean that the punishment was not structured to guarantee that Green could never be released. State’s Attorney Anne Colt Leitess said the sentence delivered accountability for Gray’s killing and removed Green from the community.
The evidentiary story that began with details recorded around a restaurant ultimately carried the case from an unsolved homicide to conviction and sentencing. The sedan’s make, color and decal were compared with Green’s car. The handgun seized from him was compared with shell casings from the scene. Clothing shown in surveillance was compared with social media images and items recovered from his bedroom. Each strand had a different origin, but prosecutors combined them into a single narrative that jurors accepted after hearing the case.
The sentence leaves the evidentiary verdict intact while the motive remains uncertain. Green maintains his innocence, and the court preserved a possible future path to parole. Gray’s family, which attended the trial and sentencing, has said the loss continues far beyond the legal proceedings. The criminal case now stands as one in which investigators could reconstruct who they believed committed the shooting through physical and digital evidence, even as the question of why a 23-year-old worker was killed during an overnight McDonald’s shift remains without a definitive public answer.
