Terrifying videos girl, 12, posted before being killed after subway surfing on NYC trains

The mom of one of the two schoolgirls found dead on the train tracks in New York City has spoken out after terrifying stunts she's undertaken appear online.

Zemfira Mukhtarov was just 12 years old when she was killed in the early hours of Saturday morning (October 4), following a subway surfing incident alongside a 13-year-old friend, Ebba Morina.

The girls were discovered dead on top of an incoming J train at at the Marcy Avenue stop in Brooklyn, with cops arriving at around 3am ET.

Upon arrival, they found 'two unconscious and unresponsive females' who were pronounced dead at the scene by healthcare professionals.

The tragedy comes just a month on from when Zemfira posted videoS on her TikTok account of her performing dangerous stunts, while her mom also shared how she would frequently sneak out of the house to carry out them out- as she did the night of her death.

Another clip uploaded on her profile included a terrifying video of her balancing on a narrow beam while a train bullets underneath her.

“I always working, and I don’t know what she’s doing, what time she’s doing,” her grieving mom Nataliya Rudenko, told The New York Post.

"One time I see she is on the top of the Williamsburg Bridge, [pretending to] hold our city on her hand.”

The suspension bridge stretches over the East River in New York City, connecting the Lower East Side of Manhattan with Brooklyn, and is 310 feet tall - which to put it into perspective, is five feet taller than the Statue of Liberty.

Rudenko, who noted that she had never heard of her friend Ebba prior to their deaths, explained that her daughter would often roam the city looking for her next thrill - climbing onto the rooftops of high-rise buildings, as well as sneaking into empty mansions.

A GoFundMe has since been set up by the pre-teen's grieving dad.

"With heavy hearts, we are reaching out for support after the tragic loss of my beloved daughter, Zemfira, who passed away in a devastating accident at a subway station," penned Ruslan Mukhtarov.

"She was 12 and she had to have her 13[th birthday] in just 2 weeks, full of life, and taken from us far too soon in a heartbreaking incident that we believe was a subway surfing accident.

"No parent should ever have to face the pain of losing a child, and no child should lose their life in such a tragic way. We are struggling to process this immense grief, and we are turning to our community for help to give Zemfira the respectful and loving farewell she deserves."

Ruslan continued: "We are raising funds to cover the costs of her funeral and memorial services, as this unexpected tragedy has left us financially unprepared.

"Any contribution, no matter how small, will help us honor Zemfiras memory and lay her to rest with the dignity she deserves. If you’re unable to donate, please share this fundraiser or keep us in your thoughts and prayers.

"Thank you for your kindness, support, and love during this incredibly difficult time."
