An off-duty New York City correction officer was shot to death in her car Sunday night in Brooklyn, police said.

Alastasia Bryan, 25, was behind the wheel of her car at Avenue L and 73rd Street in the Flatlands around 9:15 p.m. when someone came up and fired into the vehicle.

Bryan suffered gunshot wounds to her head and torso. She died at the scene, police said.

It's unclear if she was intentionally targeted or if the shooting was random, but police said Monday morning that detectives had obtained surveillance video showing a man getting out of a vehicle and walking up to Bryan's car. The video shows the man opening fire and then getting back into his vehicle before taking off, police said.

On Sunday night, investigators were seen examining the gray sedan, which had several bullet holes in its driver’s side window. A crowd gathered at the scene and several people were seen hugging and crying as police stood nearby.

The Correction Officers Benevolent Association, a union, confirmed that Bryan was a city correction officer in a Facebook post early Monday morning.

"Tonight our correction family and the entire City of New York is shocked and grieving the horrific murder of one of the youngest members of New York City's Boldest, who was shot and killed by an unknown assailant while sitting in her car in Brooklyn," COBA President Elias Husamudeen wrote in the post.

It's unclear where Bryan worked. COBA represents members working in more than 26 different jail facilities throughout the city, including Rikers Island.

A police investigation is ongoing, but police haven't named any suspects.

Just last Sunday, two men forced their way into a home in Jamaica, Queens, and shot a state corrections officer and his wife, according to police. The corrections officer was taken to a hospital in critical condition. His wife was taken in serious condition.
