THE death of an 18-year-old-girl is being investigated after police reportedly discovered a note at the scene of her death that claimed her boyfriend’s dad was responsible for her murder. Aleyna Aggul, 18, was discovered in the neighbourhood of Igdir, Turkey last Saturday after she appeared to have fallen to her death from a fifth floor apartment.

Posthumously attributing blame to the man, who is her boyfriend’s father, it read: “Gokhan Argin is responsible for my death”. According to the news site Haberler, Aleyna had been in a long-term relationship with the man’s son, also 18, at the time of the alleged incident. But, Gokhan, who works in the construction business, had allegedly decided to take advantage after seeing nude photos of Aleyna while checking his son’s mobile phone. At a date that has yet been specified, the man then allegedly called Aleyna to his office, where he is accused of blackmailing the teen with photographs and sexually abusing her. A day before her death, he was reported to police on accusations made by the young woman regarding his behaviour. The dad allegedly had told her: “I have your photos and videos. If you disobey me, I will show them to your family and friends. “Everyone will know what you’re like.” And just over 24 hours later the young teen, who also reportedly suffered from depression, was found dead below the block of flats.

After investigators examined the mobile phones and social media of the victim and suspects, Gokhan’s arrest was ordered on charges of incitement to suicide, blackmail, deliberate injury, threat, insult and violation of privacy. It came just days after he, and his son, had been detained and subsequently released due to a lack of evidence. Meanwhile, Aleyna’s devastated parents have consistently reiterated their belief that both the boyfriend and his father had pushed their daughter to her death and “made it look like suicide.” Aleyna’s father, Kemal Aggul, said: “It was not a suicide, they plotted against my daughter. There were no broken bones in my daughter’s body, just a blow to the back of her head. “They killed my daughter and left her there. They threw her from the top floor of the building where her uncle lived and made it look like suicide.” A post-mortem has now been conducted but the report, which could shed more light on the teenager’s death, has yet to be released. Meanwhile, protests over the young woman’s death in the Azerbaijani-majority city, which lies close to the border with Armenia, is due to take place this afternoon. The investigation is ongoing.

It doesn’t discriminate, touching the lives of people in every corner of society – from the homeless and unemployed to builders and doctors, reality stars and footballers. It’s the biggest killer of people under the age of 35, more deadly than cancer and car crashes. And men are three times more likely to take their own life than women. Yet it’s rarely spoken of, a taboo that threatens to continue its deadly rampage unless we all stop and take notice, now. That is why The Sun launched the You’re Not Alone campaign. The aim is that by sharing practical advice, raising awareness and breaking down the barriers people face when talking about their mental health, we can all do our bit to help save lives.
