NEW YORK — The woman killed when she was set on fire in a Brooklyn subway car has been identified by police, after using fingerprint and dental information and DNA evidence.

On Tuesday, NYPD officers identified her as 57-year-old Debrina Kawam, originally from Toms River, New Jersey.

She is believed to have been homeless and was sleeping on the subway when she was set on fire.

Mayor Eric Adams said Tuesday that Kawam briefly spent time in the city’s shelter system.

He reiterated people should not be living in the subway system, “they should be in a place of care… we cant throw up our hands and allow that to happen.”

Last week, a grand jury indicted the alleged subway arsonist on four counts of murder — one count of murder in the first degree, three counts of murder in the second degree and arson in the first degree during a hearing Friday.

Sebastian Zapeta, 33, did not appear in court for prosecutors’ brief announcement of the indictment but he must appear when he is arraigned on the indictment on Jan. 7.

Brooklyn District Attorney Eric Gonzalez said that “murder in the first degree carries the possibility of life without parole,” calling it a charge that is “more significant in state court than currently in federal court.”

“We believe very strongly that this case belongs in the state court,” he said, quickly adding, “we have a very strong working relationship with our federal partners and of course we will always do what is in the best interests” of the case.

Gonzalez thanked grand jurors who watched the graphic surveillance video of her death recovered from a subway car.

“Right around the holiday, to have to see the video and the images of a woman set on fire is very hard to deal with,” he said. “This was a malicious deed, a sleeping vulnerable woman on our subway system. This was intentional and we intend to prove this in a court of law.”

Police took Zapeta into custody while he was riding a train on the same line later that day. Authorities say he claimed not to know what had happened but identified himself in photos and surveillance video showing the fire being lit.

A Brooklyn address for Zapeta released by police after his arrest matches a shelter that provides housing and substance abuse support.

Federal immigration officials said he was deported in 2018 but returned to the U.S. illegally sometime after that.

The harrowing episode has renewed concerns about safety in the nation’s largest mass transit system.
