Friends, family, and colleagues are remembering fallen NYPD officer Brian Moore as a young man who served the city well.

Officers and members of the community have been coming out to the 105th Precinct in Queens Village to pay their respects.

Across the street at PS 33, blue ribbons are being displayed in tribute. 

The 25-year-old who was shot in the line of duty over the weekend died Monday after he was taken off life support at Jamaica Hospital.

Moore was a decorated officer with over 150 arrests and four medals in just five years of duty.

A wake is scheduled for Thursday at the Chapey and Sons Funeral Home in Bethpage. Visiting hours are 2 to 4:30 p.m. and 7 to 9:30 p.m. The funeral will take place Friday at the St. James Roman Catholic Church in Seaford, at 11 a.m.

After Moore died, hundreds of officers stood at attention outside the hospital to salute the ambulance carrying his body.

"The loss of a police officer is always tragic, it taxes us immensely. But as a police department we can take comfort in officer Moore's example," said Police Commissioner Bill Bratton.

"Our city is in mourning, our hearts are heavy. We lost one New York's Finest. And that phrase needs to be understood at this moment. We lost one of the best amongst us," said Mayor Bill de Blasio.

Flags around the city and state have been lowered to half-staff in Moore's honor.

Mourners also included members of a non-profit called Blue Lives Matter. 

"We're never going to forget him. This officer Moore was 25-years-old, young kid. He had a whole life ahead of him. We're here to make sure that the family knows that we're their family and we're their brothers and sisters now," said Jonathan Herbin of Blue Lives Matter.

In Moore's hometown of Massapequa on Long Island, hundreds of his friends and neighbors gathered Monday for a special service in his honor.

Meanwhile, the man accused of shooting Moore is now charged with first-degree murder.

The Queens District Attorney upgraded the charges Monday following the officer's death.

Police say Demetrius Blackwell opened fire on Moore and his partner after they drove up to him in an unmarked squad car.

The officers were trying to stop Blackwell after they saw him adjusting his waistband, which made them suspect he had a gun.

Investigators found the gun used to kill Moore in a backyard in Queens Village, near the scene of the shooting.

The gun still had two live rounds in it.
