Police on Friday arrested the man who they say shot and killed an aide to Gov. Andrew Cuomo last year during festivities leading up to the West Indian Day Parade.
Micah Alleyne, 24, is charged with murder, criminal possession of a firearm and reckless endangerment.
Investigators say he shot 43-year-old Carey Gabay in the head last September during J'ouvert, a celebration before the annual parade.
The Brooklyn-native and Harvard grad was not the intended target.
Police said a gun battle broke out between rival groups, and Gabay was caught in the crossfire.
Police said Alleyne is seen on surveillance video running away after the shooting.
Police are looking to make more arrests in the coming days.
"This is over a 10-month investigation. His name surfaced early. A lot of informants, or information, I should say, came forward naming him early on," said NYPD Chief of Detectives Robert Boyce. "If you remember, a lot of video evidence we collected of people running back into Ebbets Field housing development, and he matches that video that we collected."
Gabay served as the First Deputy Counsel of the Economic Development Corporation during the time of his death.
Previously, he was an assistant counsel to the governor.
Brooklyn Borough President Eric Adams hailed the arrest and said Gabay's murder scarred those who loved him and the community.
"This arrest is the starting point of the healing process that is needed for the emotional pain and the emotional road and trajectory that that bullet has put throughout our community," Adams said.
Gabay was widely admired. He grew up in public housing in the Bronx, earned an Ivy League degree, and entered public service.
In a statement, the 43-year-old lawyer's family members said they are still grieving but are encouraged that the justice process is finally moving forward.
"Carey Gabay was an exemplary public servant who lost his life in a senseless tragedy. Today's arrest is a major step forward in the pursuit of justice for Carey's family and loved ones," Cuomo said in a statement. "I commend the investigators and prosecutors for their tireless efforts to ensure those responsible for Carey's death are held fully accountable for their actions."
Police and prosecutors are still looking for others they say were involved in the shootout. They all will face murder charges.
