WATCH: Slain NYPD Cop Brian Mulkeen Honored At Funeral

MONROE, NY — Hundreds of NYPD cops traveled north of New York City Friday morning to pay their respects to the slain Officer Brian Mulkeen. The 33-year-old cop's funeral was being held in his Orange County hometown less than a week after he was killed by friendly fire in The Bronx.

Mayor Bill de Blasio and Police Commissioner James O'Neill were also on hand for the funeral at Sacred Heart Church in Monroe, where Mulkeen was raised.

"He did his job, and he didn’t think twice about it," O'Neill said inside the packed church, his voice cracking. "He didn’t hesitate, because he was a cop."

Mulkeen was struck by two NYPD bullets early Sunday morning during a struggle with an armed man who had fled from police near the Edenwald Houses in The Bronx. O'Neill has called his death "a tragic case of friendly fire."

Mulkeen was the second cop to die by friendly fire this year. Other officers fatally shot Det. Brian Simonsen during an attempted robbery at a Queens cellphone store in February.

Mulkeen arrested dangerous criminals and regularly took loaded guns off the streets as part of an anti-crime unit in The Bronx, O'Neill said.

He was disptached the night he died to a public housing complex in the borough that had been plagued by gunshots and gang violence, according to the commissioner.

"We sent them there because the people in that neighborhood needed their help," O'Neill said. "They needed to feel safe."

De Blasio recounted how Mulkeen had a cushy finance job at Merrill Lynch but left to become a police officer after he felt a call to public service.

"It was clear to Brian that his mission was to protect and serve others, to do something brave, to do something courageous," the mayor said. "Many times in life people will reach that kind of crossroads and think about what’s the right thing to do. What’s so striking is that Brian not only thought about it, he did it."

Mulkeen is survived by his parents, Camille and Brian, his sister, Erin, and his girlfriend, Sherry Hodge.
