London: Two teenagers from the same school were killed after stepping in front of a high-speed train in an apparent suicide pact.

Charleigh Disbrey, 15, and Mert Karaoglan, 18, were found on the tracks 200 yards from a busy commuter station in Hertfordshire.

They were under the arches of a brick footbridge when they were hit by a locomotive travelling at more than 90mph.

Investigators later found two notes on the body of Mert, a filmmaker and A-level student, and a single note on Charleigh, a talented musician who said she “would give anything to be famous”.

Charleigh, also known as ‘CJ’ had auditioned for the television shows Britain’s Got Talent and Must Be The Music. The GCSE pupil had posted videos of herself on YouTube playing an acoustic guitar and had written on her website that she wanted to become a musician “to be remembered”.

Just days before her death she had uploaded a haunting rendition of herself singing the David Guetta hit song Titanium.

Friends said the pair who attended Hertswood Academy in Borehamwood ‘were close’ but did not believe they were in a relationship.

Mert’s parents Hatice, 52, and Sukru, 48, who are believed to originate from Turkey, were last night too upset to speak about the tragedy.

The couple told friends: “He was a happy guy. We don’t know who Charleigh was, we don’t know why this has happened.”

It is believed the pair had clambered over a gate at Robinson’s pedestrian bridge north of Elstree and Borehamwood station to get on to the tracks.

They were struck at about 9pm on Monday by a London First Capital Connect service. No passengers were on board.

A Network Rail source said: “They stepped out together on to the track. Three notes were found on their bodies.”

The incident is not being treated as suspicious by British Transport Police.

A friend said: “CJ sang and wrote her own songs. She was a talented girl, she came across as very happy. She was always caring about other people.

“We didn’t know if they were going out together but they were close friends. Mert was very talented with the camera.”
