"This was an unprovoked direct attack on police officers who were assigned to keep the people of this city safe", Police Commissioner James O'Neill said, calling it an assassination.
NYPD officers, friends, family and residents of the Bronx gathered for a vigil on Saturday night to remember 48-year-old officer Miosotis Familia.
A wake will be held Monday for Officer Familia at World Changers Church in the Bronx and a funeral service will be held at the same church Tuesday at 10 a.m.
"Because she was very protective around here", one child from the area said.
"She can never be forgotten by the citizens of this neighborhood and all New Yorkers", Assistant Chief Larry Nikunen, the commanding office of NYPD Patrol Borough Bronx, said at the podium.
A bystander was also struck by a bullet during the encounter, police said.
"She always volunteered to work as much as she could, and it was always all for her kids".
Officer Familia didn't have to be where she was early Wednesday morning when a deranged ex-con allegedly ambushed her inside a mobile command post.
The original program had the nation's largest police department adding the protection only to its roughly 3,800 marked and unmarked patrol cars and not the command centers.
Her assassin, 34-year-old Alexander Bonds, was killed in a shootout with police. There does not appear to be any connection between Familia and Bonds, police said.
The vigil ended with a candle lighting and a balloon release.
