Corrections officers are mourning the death of one of their own after she was ambushed, shot and killed while sitting in her car in Brooklyn this Sunday.

At around 9:15 p.m., authorities found 25-year-old Alastasia Bryan dead with gunshot wounds to her head and her body inside a car on East 73rd Street and Avenue L in Flatlands.

Correction Officers’ Benevolent Association President Elias Husamudeen said the union would make sure to support Bryan’s family in their time of need.

“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,” read Husamudeen’s statement. “There are no words that can express the depth of this tragedy. The COBA will do everything we can to support the officer’s family during this time and we will not rest until the assailant or assailants are brought to justice.”

COBA’s offering a $50,000 reward to anyone who gives them information that leads to an arrest of Bryan’s killer.

New York City Mayor Bill de Blasio expressed sadness and put faith in the authorities to catch the killer.

“On behalf of all New Yorkers, I want to extend my deepest sympathies to the family and loved ones of Alastasia Bryan—a rising member of New York City’s Department of Correction who was senselessly murdered yesterday in Brooklyn,” said de Blasio, in a statement, Monday. “The NYPD is working aggressively to find the person responsible for this heinous act and will maintain its pursuit until they are brought to justice.”

New York City’s Department of Corrections took to their Twitter page to mourn Bryan.

“Tonight DOC suffered a tragic loss when an off duty officer was fatally shot,” the DOC’s page tweeted Sunday. “Our thoughts are w/the officer’s family, friends & colleagues.”

On Wednesday the page tweeted, “Today, the DOC family mourns together. Rest in peace, Correction Officer Bryan.”

At the site of her death, family members, friends and fellow corrections officers held a candle-light vigil in her honor.

Authorities believe that Bryan’s killing was a targeted move, but they don’t have any leads or motives at this time. Police said a man had been waiting around the corner from her family’s home and waited for her to get in the car before running up and opening fire.

“He got out of the car and fired five rounds into the car, striking and killer her,” said NYPD Chief of Detectives Robert Boyce during a news conference. “This male then got into a car and then drove away.”

Community Activist Tony Herbert echoed the sentiment during the vigil succinctly when speaking to the press during a news conference near the crime scene.

“That young lady should be on this planet today,” said Herbert. “No one had the authority to take her life.”
