BETHPAGE - The man accused of fatally shooting NYPD Officer Brian Moore, of Massapequa, is facing upgraded charges after the death was officially ruled a homicide.

Demetrius Blackwell is facing first-degree murder charges in the 25-year-old officer's death. Officials say Blackwell shot Moore in the head as Moore was trying to question him about a gun.

An NYPD emergency services ambulance carrying the body of the fallen officer led a procession Tuesday from Manhattan to Chapey Funeral Home in Bethpage. Dozens of police officers, firefighters and residents lined the street on the way to the funeral home.

A graduate of Plainedge High School, Moore was the son, nephew and cousin of police officers. People that knew him say he did not waste anytime signing up.

"At 17 years old, he took the police test…He was so excited that he passed the test with flying colors," said Larry Balsamo.

Moore's wake will be held Thursday at Chapey & Sons Funeral Home in Bethpage from 2 to 4:30 p.m. and 7 p.m. to 9:30 p.m.  His funeral will be held at 11 a.m. on Friday at St. James Roman Catholic Church in Seaford.
