Though many news headlines say that the teens were "kissing" on the balcony, Samson Oguntayo, a neighbor living next to the building where this happened said the two were trying to "have s3x." He also said that the "guy was lifting the girl and putting her on the bannister, he kept doing it,"
The teens were going at it hot and heavy when the people at this party heard loud noise, almost as if they were hearing large booms from fireworks. That was the noise of the couple made when hitting the pavement below.
According to Yahoo News on June 12, the party was going on inside the apartment while the two were outside on the balcony having sex. The balcony has a railing and apparently the guy was trying to perch the woman on the edge of the railing during sex. Somehow they lost balance and simultaneously went over the side to their death.
Oguntayo said he ran to the building next door to find the two teens lying in pools of blood. He called 999, which is the equivalent to America's 911emergency number. He knew it was too late and when the paramedics arrived they could not save either teen.
Sky News today reports the police in London are calling the teens death a "tragic accident," which suggests they don't believe any foul play was involved. The police were called to the Knights Tower in Deptford, South London after midnight. Oguntayo told police they were doing some "really dangerous stuff" on the balcony.
Oguntayo said he reached the bodies first and he had to tell their friends that the two of them were dead. After the incident people from the party could be seen out on the balcony crying.
The neighbor who witnessed the couple fall said the girl had her arms around the boys neck when they lost their balance. Police are asking any witnesses to get in touch with them, but they did say they are not treating this tragedy as suspicious.
Both teens are students at Bellerbys College in London and the party was a celebration of the end of finals.
Update 6/13: Much like the movie "Rear Window" people of this apartment complex can see many other windows and balconies of the building where the accident happened. A few of the neighbors had spotted the couple going at it on the balcony and happened to be watching when they lost their balance and fell over. People gazing is popular in the big cities like New York, where telescopes are often used to check out the sights.
