Two teens died in a "tragic accident" in London on Tuesday—which witnesses say involved sex. The international students—an 18-year-old from Mexico known only as Miguel and 19-year-old Anastasia Tutik of Russia—hit it off at a party celebrating the end of exams, the Daily Mail reports. "He liked her and she liked him so they went onto the balcony to make out," a fellow student told the Telegraph. That's when things went awry. "They were trying to have sex on the balcony, the guy was lifting the girl and putting her on the banister, he kept on doing it," a witness who lives nearby said. "The last thing I expected was to see them falling down five floors. We just screamed."
Another witness said she heard "a very, very loud noise and a lady screaming initially—I heard a boom and at first I thought a firework had gone off or something." Meanwhile a bystander jumped a fence and discovered the couple "surrounded by a massive pool of blood," the Mirror reports. Both were pronounced dead at the scene after falling some 60 feet from the building's sixth floor. The man had only just arrived in London from Monterrey, Mexico, to study for the summer, a friend said, adding Tutik "was one of the top students in the class. She was studying A levels and she was hoping to go to university in September." (Another sex accident recently grabbed headlines in China.)
