A 13-year-old boy is dead, another was injured after trying to ride to the top of the New York subway

A 13-year-old girl was killed and a 12-year-old woman was injured in a subway surfing incident in Queens, New York.

In an email to PEOPLE on Tuesday, October 29, a New York Police Department (NYPD) spokesperson said that on Sunday, October 27, authorities responded to a 911 call about a person who had been struck by a train at the 111 Street subway station, where line 7 runs.

“Upon arrival, officers observed (a) 13-year-old female unconscious and unresponsive, and she was pronounced dead at the scene by emergency services,” the spokesman said. “An additional 12-year-old female was transported by EMS to NYC Health and Hospitals/Elmhurst in critical condition.”

The NYPD has identified the 13-year-old girl who was killed as Krystel Romero of Brooklyn, New York.

According to police, the two girls were apparently subway surfing. NBC affiliate WNBC, Fox affiliate WNYW, ABC affiliate WABC and local station WPIX reported.

The NYPD said the investigation is ongoing.

“We didn’t hear any commotion, but the car suddenly stopped,” the passenger said, according to WPIX. “Then the lights went out and we sat there for about five minutes with the lights off… and then we were told to leave the train.”

PEOPLE reached out to the MTA for comment, but there was no immediate response.

On Monday, October 28 Post X (formerly on Twitter).New York Mayor Eric Adams wrote in response to the tragedy: “Heartbroken to hear that subway surfing – and the pursuit of social media influence – has stolen another life.”

“We’re doing everything we can to raise awareness of this dangerous trend, but we need all New Yorkers – and our social media companies – to do their part too. No post is worth your future,” he continued.

“My prayers are with the families of both girls,” Adams concluded.

According to Gothamistthe October 27 incident is the sixth subway surfing-related fatality on the city’s transit system this year.

“I see it in the morning and after school. I leave work around 4 or 5 p.m. and sometimes the trains stop because they have to stop for subway surfing,” a passenger recently said CBS affiliate, WCBS.

The MTA had its say website there were four subway surfing fatalities last year, and added that he has worked with NYPD and New York City police students on a campaign to discourage people from the dangerous activity through activities such as public service announcements and social media posts.

“The aim of the campaign is to remind the public, especially young people, that traveling on subway cars is reckless and dangerous, and often leads to tragedy for the injured person and their loved ones,” the agency said.
