A Nebraska teen accidentally shot himself in the head while posing with a gun in an internet chat room. Shocked users looked on in horror as 19-year-old Trevor George pulled out a revolver, held it up to his head and pulled the trigger in early March, killing himself.

After a three-month investigation, Bellevue police concluded on Monday that the horrific death was an accident not a suicide.

They also determined, after interviewing witnesses and reviewing computer records, that George was not dared or bullied into shooting himself.

Several people who were in the Tinychat video chat room George was logged into when he died told police the Bellevue University student had put a gun to his head before as a joke but it was never loaded.'He has a history of simulating this event,' Capt. David Stukenholtz said. 'This time, for whatever reason, there was a bullet in the chamber of the gun that he did not get out of there.'

Police said most of the people in the chat room didn't know George's real name or where he lived, making it difficult for them to report the shooting or call for help. 'Even if you knew his name, you would have to know where to send help,' Stukenholtz said.

Some of the witnesses contacted by Bellevue police live in Australia, Canada, the Netherlands and elsewhere in the United States.

The deadly accident was eventually reported by a Florida man who knew George's real identity and had been logged into the chat room before the shooting.

He told police he had logged back in the following morning and found people talking about the devastating event.

George lived with his parents in the Omaha suburb of Bellevue.His parents were home at the time of the shooting, but did not hear the shot and weren't aware of their son's death until officers arrived to check out the Florida's man's report.

Users posted confused messages on the chat room after the shooting. One, who goes by the screen name 'Strawman' wrote: 'I talked to him in his last seconds. I didn't realise he was dying.'

Police said George was a star student and didn't appear to be depressed or suicidal。

【新闻快讯】2012年3月3日，美国内布拉斯加州一名19岁少年疑似在网络视频聊天时朝自己头部开枪身亡。经过3个月的调查取证，警方认定这是一起意外事故，而不是自杀。

当地警长史戴西说，警方3月3日早上接到一名佛罗里达州男子报案。这名男子2日晚间也在同一个聊天室聊天，下线之后隔天早上再次登入时，发现其他网友都在谈论该案。史戴西希望能够找到目睹少年死亡的聊天室用户，询问案情。

警方3月6日表示，聊天室其他成员很有可能直接目击了这幕骇人的景象。据称报案男子认识死亡少年。接到报案后，警方赶往少年与父母在奥玛哈郊区的住所，在少年的房中发现了他的尸体。调查人员正试图查清此案到底是自杀还是意外。

史戴西说，事件据信发生在3月3日清晨3时，并表示不清楚少年死亡的过程是否被录像。调查人员目前正检查这名少年的电脑，希望找出当时在聊天室内目睹案发经过的网友。史戴西表示，在调查人员尚未查出这些聊天室账号使用者的真实身分前，警方无法确定是否有目击者。他说，“网站上有些人用的是化名，这些化名有时很难追查到任何东西，我们从没有经历过这么棘手的调查。”

而经过3个月的调查之后，该少年的身份被确定，他名叫特雷福·乔治，在学校里是一名明星学生，没有任何抑郁和自杀的倾向。他经常在聊天室中表演枪击自己，但枪中都没有子弹。但3月3日凌晨他表演时，枪中装填着子弹，他忘了将子弹取出，因此才酿成了惨剧。
