SEAFORD - Thousands came together today for the funeral of the NYPD officer from Massapequa who was shot last weekend.

Officer Brian Moore was posthumously promoted to the rank of detective by NYPD Commissioner William Bratton during his funeral at St. James Church in Seaford. Moore, 25, was shot Saturday in Queens Village as he was trying to question a man about a gun. He died Monday.

An estimated 30,000 officers, from as far away as Canada, Florida, California and Texas, showed up in support of the slain officer.

Rep. Peter King and New York Mayor Bill de Blasio were among the mourners. King says he came to honor the officer and his family.  De Blasio took notice of Moore's bravery and police bloodline.

"It's a show of strength and support for real people - real Americans and people in the neighborhoods, in the community," said King.

"He was brave, for sure, but his bravery was matched by his compassion, and he came by it through his family. It was in his DNA," said de Blasio.

In his homily, NYPD Chaplain Robert Romano praised the 25-year-old as a true American hero who always smiled and cared deeply for his family.

Moore was laid to rest at a private burial at St. Charles Cemetery in Farmingdale.

Moore had 150 arrests in just five years on the job and had earned several meritorious service medals.
