A funeral was held Tuesday for a New York City correction officer shot to death while sitting in her car in Brooklyn.

Alastasia Bryan, 25, was laid to rest at Canarsie Cemetery in Brooklyn. Those in attendance at the funeral say Bryan is fondly remembered as a person who made a large impact on the correction department.

On Dec. 4, investigators say Bryan was sitting in the car near East 73rd Street and Avenue L in Flatlands when a gunman approached and fired at least four shots into her vehicle. Surveillance video shows the attacker lurking nearby before ambushing her.

Police say a second suspect was also involved. The two reportedly fled in a gold-colored sedan. Police say they believe an ex-boyfriend of Bryan's to be a person of interest, but he may have left the state.

Bryan was a rookie correction officer who had been on the job for just a month.

Police and the mayor are offering a $20,000 reward for information leading to a conviction in the case. Anyone with information is asked to call Crime Stoppers at 1-800-577-TIPS.
