Officer Brian Moore had already started carving out a promising career for himself at the New York Police Department. He made more than 150 arrests and earned service medals in less than five years on the job.

But that trajectory ended Monday. The 25-year-old was pronounced dead at a Queens hospital, two days after being shot in the head by a man with an extensive criminal record, including serving five years in prison on an attempted murder conviction.

Prosecutors say Demetrius Blackwell will be charged with first-degree murder. He was charged earlier with attempted murder and other crimes. He's being held without bail and hasn't entered a plea. His attorney has denied the charges.

Police Commissioner William Bratton says Moore was "an exceptional young officer."
