NEW YORK (AP) — A man accused of setting a woman on fire inside a New York City subway train and then watching her die after she was engulfed in flames is awaiting arraignment on Tuesday.

Sebastian Zapeta, 33, was arrested on murder and arson charges in the woman’s death Monday, but was yet to appear in front of a judge as of Tuesday morning.

Federal immigration officials said Zapeta is a Guatemalan citizen who entered the U.S. illegally after he was previously deported in 2018.

The apparently random attack occurred Sunday morning on a stationary F train at the Coney Island station in Brooklyn. Police said Tuesday that identification of the victim was still “pending at this time.”

Authorities say Zapeta approached the woman, who was sitting motionless in the train car and may have been sleeping, and used a lighter to set her clothing on fire.

The woman quickly became engulfed in flames, while the suspect then sat at a bench on the subway platform and watched, according to police.

Video posted to social media appeared to show the woman standing inside the train ablaze as some people look on from the platform, and at least one officer walks by. NYPD Chief of Transit Joseph Gulotta said Sunday that several officers had responded to the fire and one stayed to keep the crime scene “the way it’s supposed to be” while the others went to get fire extinguishers and transit workers.

They were eventually able to douse the fire, but “unfortunately, it was too late,” Police Commissioner Jessica Tisch said — the woman was pronounced dead at the scene.

Zapeta was taken into custody Sunday afternoon while riding a train on the same subway line after police got a tip from some teenagers who recognized him from images circulated by the police.

It was unclear if Zapeta has an attorney. A Brooklyn address for Zapeta released by police matches a shelter that provides housing and substance abuse support. The shelter did not immediately respond to a request for comment.

In a statement, Brooklyn District Attorney Eric Gonzalez called the attack a “gruesome and senseless act of violence against a vulnerable woman” that would be “met with the most serious consequences.”

The crime — and the graphic video of it that ricocheted across social media — deepened a growing sense of unease among some New Yorkers about the safety of the subway system in a city where many residents take the subway multiple times each day.

Overall, according to authorities, crime is down in the transit system this year when compared to last year — major felonies declined 6% between January and November of this year and in 2023, data compiled by the Metropolitan Transportation Authority show. But murders are up, with nine killings this year through November compared to five in the same period last year.

Earlier this month, a Manhattan jury acquitted Daniel Penny in the death of an agitated subway rider that the former Marine placed in a chokehold last year. The case became a flashpoint in ongoing debates over safety, homelessness and mental illness on the system.

Policing the subway is also difficult, given the vast network of trains constantly moving between the system’s 472 stations, with each stop containing multiple entry points and, in many stations, multiple floors and platforms. On Sunday, police at the station where the woman burned to death were patrolling a different area and responded after seeing and smelling smoke, authorities said.
