Following the tragic death of NYPD Officer Brian Mulkeen in the early hours of September 29, a memorial fund has been set up on GoFundMe.

Officer Mulkeen served on the force since January 2013 and lost his life while answering a call in the Bronx. The 33-year-old was involved in a struggle with an armed suspect and was unfortunately killed by friendly fire. Below, the NYPD explain what transpired.

New York Governor Mario Cuomo paid this tribute to the fallen officer:

“I am absolutely heartbroken by the tragic loss of NYPD Officer Brian Mulkeen, who was shot and killed in the line of duty early Sunday morning in The Bronx. At 33, Officer Mulkeen was taken far, far too early from his family and from the city he sacrificed everything to protect. He is the embodiment of bravery and a true New York hero. On behalf of the New York family, I extend my deepest sympathies to Officer Mulkeen’s family and loved ones during this excruciatingly painful period and I ask all New Yorkers to keep them in their prayers.”
