Allen is charged with murder in the second degree, manslaughter in the first degree and menacing in the second degree.
Allen, 28, was off-duty when he killed Christopher Curro, who was 25 at the time of his death, in Farmingdale, Nassau County.
“We trust our police to protect the safety of New Yorkers, but instead, this defendant allegedly betrayed that duty and used his service weapon to end another man’s life,” James said. “My office is committed to ensuring justice is served and that no individual is above the law.”
According to the attorney general’s office, Allen and Curro were longtime friends who both lived in Nassau County.
On May 12, 2020, around 8 p.m. in a residential neighborhood, Allen allegedly shot Curro five times at close range. Curro was unarmed. Allen initially fled the scene but returned later in the evening.
Allen had been a police officer for seven months assigned to the 109th Precinct in Queens. The NYPD suspended and later terminated him after the alleged murder.
Allen was arraigned on Aug. 20 before Judge Francis Ricigliano of the Nassau County Court. Allen is due back in court on Sept. 23, 2021.
