Girl dies while having s3x in car with older man.

A 15-year-old girl died while having sex in a car with a 26-year-old man.

Though the police are still awaiting the results of a post-mortem, the teenager is suspected to have died of an apparent heart attack.

Gabrielly Dickson Alves Nascimento was rushed to hospital on Thursday, July 29 after the unnamed man realised she had passed out while they were having sex.

He told police that he had been having sex with the teen when her lips and skin turned pale and her hands “twisted back” behind her in a spasm.

Doctors at the the UPA Jardim Casquiero medical facility in Cubatão, São Paulo, diagnosed a cardiopulmonary arrest but were unable to save Dickson, and she died in the early hours of the following morning, July 30.

An initial medical examination found blood in the girl’s vagina, but there were no other indications of a physical assault.

The older man, described as a “general services assistant” is not believed to have been charged with any crime because in Brazil, the age of sexual consent is 14.

Friends, family and neighbours have paid tribute to the teenager via social media.

The girl’s friends and classmates described her as hard-working, dedicated, happy and loved by everyone.

Dickson’s final post on Twitter, shared just two days before her death, read: “Who is it that hates me?”
