A man accepted a plea agreement on Monday for his role in a mass shooting at the Brooklyn Homes housing project that killed two people and wounded 28 others, one of the largest acts of violence in Baltimore in recent memory.

Tristan Jackson acknowledged that prosecutors could prove that he fired a gun in the direction of seven people who were running away or into the air to scare them on July 2, 2023, during an annual celebration called Brooklyn Day.

As part of the plea agreement, Jackson, 19, of Hillen, faces between five to 12 years in prison. That’s along with 25 to 50 years of suspended time.

Baltimore Circuit Judge Lynn Stewart Mays is set on April 29 to sentence Jackson on charges of conspiracy to commit first-degree assault, second-degree assault, use of a handgun during the commission of a crime of violence and possession of a regulated firearm under 21.

Jackson initially had been facing seven counts of attempted first-degree murder and related offenses.

He’s being held in the Maryland Reception, Diagnostic and Classification Center without bail.

Aaliyah Gonzalez, an honors student who had recently graduated from Glen Burnie High School, was pronounced dead at the scene. She was 18.

Kylis Fagbemi, a forklift operator who wanted to become a traveling ultrasound technician, died at a hospital. He was 20.

No one has been charged in their killings.

Jackson is the fifth and last remaining person facing prosecution in the mass shooting to take a plea deal. He had been scheduled on May 12 to stand trial.

Between 800 to 1,000 people had gathered at the housing project for Brooklyn Day, which featured dancing, pony rides and snowballs.

At about 10 p.m., Jackson arrived in a car at the block party with three other people, including Aaron Brown, said Assistant State’s Attorney Michael Dunty, chief of the homicide division in the Baltimore State’s Attorney’s Office.

Baltimore Police determined that at about 12:30 a.m. “unknown individuals began discharging multiple firearms causing terror among the attendees of the event,” Dunty said.

Brown, he said, admitted after being taken into custody on an outstanding warrant that he fired a gun into the road on Gretna Court at three people who were shooting at him.

Police found a Glock 17 in the basement of his home and reported that firearms testing revealed that it was consistent with being one of the guns fired at the event.

Surveillance video shows Brown hand something to Jackson, Dunty said.

Jackson, he said, then appears to fire five rounds on 8th Street near Stoll Street in the direction of “seven unknown individuals” who were running away. But Jackson “could have been firing the weapon in the air to scare those victims,” Dunty said.

Next, Jackson, he said, drove Brown to the hospital to seek treatment for a gunshot wound to the hand.

At the time, Jackson was on GPS monitoring in an unrelated case.

Assistant Public Defender Matthew Connell, one of Jackson’s attorneys, said his client disputes that he drove Brown to the hospital or fired a gun.

Brown, 20, of Baltimore County, pleaded guilty in 2024 to conspiracy to commit first-degree assault in the mass shooting.

He also pleaded guilty to attempted first-degree murder and use of a handgun during the commission of a crime of violence in a shooting that took place on Harford Road near Grindon Avenue in Northeast Baltimore on May 19, 2023.

As part of a plea agreement, Brown was sentenced to 12 years in prison plus five years' probation. Forty-eight years were suspended.

Baltimore City Council held hearing about the mass shooting.

Police also released a 173-report about their ill-advised and hands-off approach to the event, which found that officer indifference played a role.
