Thousands gathered outside Fredrick J. Chapey & Sons Funeral Home in Bethpage on Thursday afternoon for NYPD Officer Brian Moore’s wake. 

Tens of thousands of family, friends, police officers and public officials are expected to pay their respects to Moore at his wake and funeral, scheduled for Friday morning. 

It has been less than a week since Moore, 25, was shot in the face after questioning a man in Queens Village about a suspicious item in his waistband. Moore died in Jamaica Hospital two days later.

The suspect, Demetrius Blackwell, was apprehended about 90 minutes after the fatal shooting, and a Taurus revolver believed to belong to him was found in a nearby backyard on Monday, police said. He is being held without bail on first-degree murder charges, and a Queens grand jury is being presented evidence in the case. 

Law enforcement officers lined the streets in front of the Long Island funeral home, waiting for Moore’s body. Gov. Andrew Cuomo paid his respects shortly after the wake started, with Mayor Bill de Blasio attending later in the day. 

A funeral mass will be held at 11 a.m. Friday at St. James Roman Catholic Church in Seaford, with first-responders across the country expected to attend. After the funeral, the fallen officer will be interred at St. James Roman Catholic Cemetery in Farmingdale. 

The NYPD is offering a $17,500 reward for information relating to Moore’s death, according to a flyer being circulated by the 105th Precinct

On Thursday, Mayor Bill de Blasio and Police Commissioner Bill Bratton honored 18 police officers who were killed in 2014, adding their names to a commemorative will inside One Police Plaza.

“Our thoughts and prayers today are with the family of Officer Brian Moore – a family that has done so much for the city and has been so deeply a part of this department,” said Mayor Bill de Blasio on Thursday, speaking at the memorial wall.

Detectives Wenjian Liu and Rafael Ramos, who were shot and killed while sitting inside their police car in Bed-Stuy in December, were added to the wall. Det. Dennis Guerra died from smoke inhalation after rushing into a Coney Island fire, and Officer Michael Williams was killed when a police van crashed in the Bronx. The remaining 14 officers died from 9/11-related illnesses. 

“They loved this city, and they gave it their all,” de Blasio said. “They made the ultimate sacrifice so others could be safe.”
