A woman who died after being set on fire in a New York subway this month has been identified, police said.

The woman was named as 61-year-old Debrina Kawam of Toms River, New Jersey, the NYPD said.

According to police, Kawam was sleeping on a stationary F train at the Coney Island-Stillwell Avenue station in Brooklyn on the morning of Dec. 22 when she was allegedly set on fire by a 33-year-old undocumented Guatemalan citizen.

The suspect, Sebastian Zapeta, is charged with first- and second-degree murder and arson. He has not yet entered a plea.

“The depravity of this terrible crime is unimaginable, and my office is committed to bringing the perpetrator to justice,” Brooklyn District Attorney Eric Gonzalez said in a statement released shortly after the murder. “This cruel and senseless act of violence against a vulnerable woman will have serious consequences.”

The suspect allegedly “approached the victim and lit her on fire with a lighter,” police said.

Officers in the area smelled smoke at the time and went to the train to investigate. There they found the woman standing in the car “completely engulfed in flames,” the NYPD said. She was pronounced dead at the scene.

According to police, images of the suspect were captured on officers’ body cameras as he sat on a bench nearby after the incident at the scene.

These images were released as police asked the public for help in identifying the man.

Three high school students recognized the suspect and called the police.

According to police, Zapeta was arrested a few hours after the incident in a subway car in Herald Square. When he was caught, the suspect had a lighter in his pocket.

A motive for the crime is still under investigation.

Zapeta was initially brought back to Guatemala from the United States in June 2018 after U.S. Border Patrol met him in Sonoita, Arizona, a U.S. Immigration and Customs Enforcement spokesman said. He illegally re-entered the United States at an unknown time and place, the spokesman said.

ICE’s Enforcement and Removal Operations will house an immigration detainer at the NYPD site where Zapeta is being held, an agency spokesman said.

During a news conference on Tuesday, New York City Mayor Eric Adams said Kawam briefly stayed at a homeless shelter in the city. He said authorities had contacted their next of kin but he did not release any further information about them.

“Our condolences go out to the family,” Adams said, calling the murder a “horrible incident to live through.”

He said such high-profile “random acts of violence” had overshadowed the police’s success in fighting crime in the subway system. NYPD crime statistics show overall crime in the subway system was down 5.4% on Sunday compared to last year.

“It was just a bad incident and it has an impact on the feelings of New Yorkers,” Adams said. “But it really proves what I’ve been saying: People shouldn’t live in our subway system. You should be placed in a care facility. And no matter where she lived, that shouldn’t have happened.”
