BALTIMORE (WBFF) — The Brooklyn Day mass shooting remains one of the darkest chapters in Baltimore’s history. Thirty people were shot and two were killed, 18-year-old Aaliyah Gonzalez and 20-year-old Kylis Fagbemi.

City leaders have long maintained they were unaware of the event before gunfire erupted. But FOX45 News learned there were Safe Streets workers at the scene, prior to chaos. Four Safe Streets violence interrupters mediated five conflicts before the end of their shift.

Now, three years later, as the families of the victims sue the Housing Authority of Baltimore City, HABC) the tragedy is once again drawing attention to longstanding questions about Safe Streets, communication protocols and accountability.

An after-action REPORT revealed that between 8 p.m. and 10:30 p.m. the night of the party, four Safe Streets violence interrupters mediated five separate conflicts at the event.

According to the report, those workers convinced people who were known or believed to have a gun to put them away. Despite those interventions, the information about weapons being present at the crowded gathering was never relayed to Baltimore Police.

The Safe Streets workers’ shifts ended before the mass shooting unfolded. It remains unclear whether any of the weapons involved in those earlier mediations were later used in the shooting.

When FOX45 News previously asked about the protocol for sharing information about potential threats at large events, the Mayor’s Office of Neighborhood Safety and Engagement, MONSE, Stefanie Mavronis acknowledged there was some communication between agencies but questioned whether reporting that information fell within Safe Streets’ responsibilities.

“I don’t know if Safe Streets would relay this. There is some level of communication… outside their purview,” Mavronis said.

Following the shooting, Baltimore Police launched an internal investigation that ultimately resulted in discipline for staff members.

“If you don’t do your job and we are able to find out through investigation that you didn’t do your duty that you knew you were supposed to be doing, this will happen to you,” Mayor Brandon Scott said when announcing the disciplinary action.

But while police employees faced internal consequences, questions lingered over whether Safe Streets workers or city officials overseeing the program were ever held accountable for the communication breakdown.

For years, FOX45 News has investigated Baltimore’s Safe Streets program, a cornerstone of Mayor Brandon Scott’s community violence intervention strategy.

The city currently operates 10 Safe Streets sites. While nonprofit organizations including LifeBridge Health and Catholic Charities oversee day-to-day operations and directly employ violence interrupters, funding and oversight flow through MONSE.

One recurring question has been what constitutes as a mediation and when, if at all, a situation should be escalated to city leadership or law enforcement.

About six months after the tragedy, Mayor Scott announced a new escalation policy requiring violence interrupters to notify MONSE leadership when potentially dangerous situations arise.

“Escalating incidents like what we saw in Brooklyn where those on the ground will notify administration in MONSE about what’s happening and then thus allowing those individuals at the top levels of MONSE to make further decisions. It’s that simple,” Scott said at the time.

While the lawsuit does not specifically target Safe Streets or MONSE, it has renewed attention on the city’s overall response to the tragedy, including questions about what officials knew before the shooting and whether opportunities existed to prevent it.

FOX45 News continues to investigate Baltimore’s Safe Streets program, including its oversight, reporting requirements and accountability measures.
