Thousands of police officers from around the country have packed a church for the funeral of a young New York City police officer who was killed on patrol.

Fellow officers carried Officer Brian Moore's coffin into the Long Island church, where the funeral Mass began Friday with hymns and readings. There was heavy security: A sniper stood on top of a police van as a hearse carried his body from a funeral home, and snipers watched from the roof of a nearby elementary school.

Authorities imposed a 3-mile no-fly zone overhead, and a Nassau County police helicopter was hovering.

The 25-year-old Moore died Monday, two days after he was shot in Queens. He and his partner were in an unmarked car and had stopped a man suspected of carrying a handgun when the suspect shot Moore in the head.

As many as 30,000 officers from across the country were expected at the funeral in Seaford.

Mourners also included New York's top elected representatives and relatives of Officer Wenjian Liu (WEHN'-jihn LOO'), one of two New York City officers killed in an ambush in December.
