"All lives matter, whether high profile or not," Cumbo said.

Gabay, 43, was shot during J'Ouvert celebrations on Bedford Avenue, near Montgomery Street at 3:40 a.m. on Sept. 7.

A day after the shooting, Police Commissioner Bill Bratton said he believed that Gabay was caught in the crossfire between two rival rival gangs.

Police released video of two armed suspects seen running from the shooting into the Ebbets Field apartments.

The NYPD was offering a $12,500 reward for information leading to their arrest.

Tamesha Fulmore, who has lived in Ebbets Field Apartments for 33 years, said she attended the rally because the community is "worried as parents and mothers."

Fulmore that she is worried especially about young people in the community.

"Our children are just dying too young," she said.

Gabay had been in a coma for 10 days at Kings County Hospital before being listed as brain dead Wednesday. He died later that day.

"He was a friend and role model to the many people who were blessed to have known him and he will be greatly missed," Cuomo said. "The state of New York has lost one of its finest men."

Gabay grew up in housing projects in The Bronx and attend Harvard University and Harvard Law School before joining the Cuomo administration as general council for the Empire State Development Corp.

At the march, Rabbi Eli Cohen of the Crown Heights Jewish Community Council offered a prayer for Gabay.

"The tragedy of a soul that is cut off before its time is a tragedy for the entire universe."

Brooklyn Borough President Eric Adams called for increased funding for grassroots anti-violence groups like Save Our Streets who were doing "the real work" in the wake of Gabay's death.
