The straphanger who was burned to death on a Brooklyn train has been identified as a New Jersey woman, police announced Tuesday — more than a week after the horrific attack.

The charred body of Debrina Kawam, 57, of Toms River, was ultimately ID’d through fingerprints, sources told The Post.

Kawam, who was described as homeless, had slept on an F train in the Stillwell Avenue-Coney Island station on Dec. 22 when she was allegedly set on fire around 7:30 a.m. by illegal Guatemalan immigrant Sebastian Zapeta-Calil, who now faces first-degree murder charges.

Horrifying video footage from the arson attack shows the accused killer fanning the flames as Kawam was consumed by the fire — and calmly watching the scorched victim from a bench on the platform.

The identification surprised Tom Rivers resident Olga Corpion, who bought the house Kawam’s mother once lived in. Corpion said she received an unexpected visit from Kawam shortly after buying the house, which was listed as the victim’s last known address, in a quaint cul-de-sac dotted with one-story Cape Cod houses.

“She said, ‘Hi, my name is Debrina, and I want to go see my mom. My mother lives here. I want to talk to her,’” Corpion told The Post. “She looked like she was in her 50s, so right away I assumed she was not well, because she didn’t know her mom had moved.

“I’m in shock that she was standing right here and then I found out she died so horribly.”

Corpion said Kawam didn’t appear to be homeless, at least in May, as she appeared to have an Uber waiting for her during their short, 10-minute interaction. 

“In my mind, I thought she had some from an assisted living facility,” Corpion said. “She was dressed fine. She did not look like somebody who was homeless.”

Another neighbor of the home, Valerie Waskiewicz, said she recalled two women living in the Toms River home. The younger woman, presumably Kawam, cared for the older one, she said.

“There are a lot of people caring for family members that are elderly, and their behavior was perfectly normal for what they did,” she said. “So this is an absolute shock to me. And if this is this woman, it’s horrible and I don’t know how this could have happened to her. She’s so far out of where she should have been, that this happened to her. It makes no sense.”

Sources said Kawam had been living in Big Apple shelters since at least Sept. 9.

She had been given a bed at the Franklin Williams Women’s Shelter in the Bronx on Nov. 30, but left on Dec. 2, the sources said.

She had at least three prior scrapes with the police — a transit bust for alcohol on April 28, a 2010 disorderly conduct charge in Maryland, and a New Jersey prostitution bust in 1994, according to law-enforcement sources.

“She resided in New Jersey and had a brief stint in our shelter system,” Mayor Eric Adams said Tuesday. “Our hearts go out to the family for this horrific incident.

“It was just a bad incident and impacts how New Yorkers feel,” the mayor said. “But it really reinforces what I’ve been saying, people should not be living on our subway system. They should be in a place of care. 

“No matter where she lived this shouldn’t have happened.”

A source also told The Post she was alive when she was set on fire, with a walker and several bags nearby.

The city medical examiner struggled to identify the body because it was so severely burned in the attack, sources previously said.

Zapeta-Calil, who was arraigned on first- and second-degree murder and arson charges, is being held at Rikers Island without bail.

Federal immigration officials said he entered the US illegally in 2018 but was deported less than a week later — only to find his way back into the country and to the Big Apple.

By March 2023, he was living in the New York City shelter system.

A pal at the Brooklyn facility where he last shacked up told The Post the migrant was addicted to smoking the synthetic drug K2 and drank heavily on a daily basis.

The accused killer allegedly told cops he was so high, he didn’t remember lighting the fire.

“He smoked K2, drank and bugged out,” said shelter resident Raymond Robinson, who slept on a cot at the facility next to Zapeta-Calil until his arrest.

“He would bug out and talk to himself when he was high, but never harmed nobody but himself,” Robinson said. “That’s why this s–t f–ked my head up because I slept next to him and he was never like that. I wouldn’t leave my daughter with anybody but he was the type of dude I could trust.

“As long as he wasn’t high,” he added.

Robinson said Zapeta-Calil liked to drink Voda vodka, “the cheapest s–t there is.”
