The suspect, identified as 33-year-old Sebastin Zapeta, is believed to have entered the US from Guatemala approximately a year ago. It remains unclear whether he entered the country legally or illegally.

During a press conference Sunday evening, New York Police Department (NYPD) officials, including Police Commissioner Jessica Tisch, explained, “As the train pulled into the station, the suspect calmly walked up to the victim. The female victim was in a seated position.”

“The suspect used what we believe to be a lighter to ignite the victim’s clothing, which became fully engulfed in a matter of seconds.”

Officers on patrol at the station were alerted to the situation by the smell and sight of smoke. While responding at the scene, they discovered a person inside the train car fully engulfed in flames. The fire was extinguished with assistance from an MTA employee using a fire extinguisher. The victim was pronounced dead at the scene.

Zapeta remained at the scene after the incident. He was found seated on a bench outside the train car. Body-worn cameras worn by responding officers captured clear footage of the suspect. Tisch noted, “Body-worn cameras on the responding officers produced a clear and detailed look at the killer.”

Following the release of the suspect’s description and photographs to the public, three high school students recognized the man and called 911. Transit officers confirmed the description and located the suspect on a moving train. The train was stopped at the next station, where officers boarded, identified the man, and arrested him without further incident.

New York City Mayor Eric Adams expressed his condolences to the victim’s family, calling the attack a “senseless killing.”

“Grateful to the young New Yorkers and transit officers who stepped up to help our NYPD make a quick arrest following this morning’s heinous and deadly subway attack. This type of depraved behaviour has no place in our subways, and we are committed to working hard to ensure there is swift justice for all victims of violent crime.”

Tesla boss Elon Musk also took to X (formerly Twitter) to express his frustration. “Enough is enough,” he posted, along with the Guatemala migrant’s subway CCTV shot.
