A Long Island street was named after Peter Figoski on what would have been the police officer's 49th birthday.
Figoski was shot and killed while responding to a robbery in East New York on December 12, 2011.
The officer's four daughters and his mother unveiled the sign dedicated to Figoski in a ceremony Saturday on the West Babylon block where he lived.
"I am heartened by the sign because it reinforces that we are never going to forget him," said Police Commissioner Ray Kelly, who was among dozens of members of the NYPD who came to honor Figoski.
"We can never bring him back and that's all his daughters want, they just want to be with their father," said Jeffrey Maddrey, Figoski's chief.
