YouTube Libyan Murder! True or Hoax?

Couple of days ago I was on YouTube looking for new Libyan uploads, usually my favourites are video showing places in Libya, what I usually do is type Libya in the search box and look for new additions, I found new videos by the Libyan comedian Hatem Elkour so I clicked on one and watched it, very funny then I started looking through the link on the side when I suddenly saw something that grabbed my attention, it was a video titled. the murder of the Libyan traveller Yousef in Cairo, I clicked on it and I was shocked and disgusted to see a video posted by a group calling itself The Sons of Free Libya, basically it was a video glorifying the murder of a Libyan teenager in Cairo carried out by the above mentioned group, I had no idea who the victim was but it was easy to find many videos posted by him, this Libyan teenager who could not be much older than 17, lets just say lived a different life style than what most Libyans would approve of and many of his videos showed him being quite open about the way he was, he was given the name of Yousef the Libyan Traveller because of his extensive travel through out the world even at this young age, of course because of his DIFFERENT life style, there were many comments having a go at him and calling him all sorts of bad names and an embarrassment to Libya and so on...

Back to the offensive video posted by the sons of free Libya, it showed a man with his face hidden behind a scarf and holding a machine gun saying that they carried out God's justice and murdered Yousef for he was bad for Libya then went on to say that Yousef was working for Israel and deserved to die but they never showed any evidence of this! they then showed a fuzzy picture of a body dressed in long shorts, you can not see the head and it says that this is the body of Yousef after he was murdered and burnt, to be honest I am shocked that YouTube allowed such a video to be uploaded on their website! I read most of the comments on this video and others and many of them seem to insist that the whole thing is a hoax orchestrated by the victim himself, that he loves attention and publicity and many said that he is alive and will eventually show up to say that somebody did this to ruin his reputation! many others have insisted that Yousef was actually killed and his body flown back to Benghazi where he was buried last week, there were some comments saying he got what he deserved but the vast majority were decent comments, many did not approve of his life style but said if he was dead then we should not speak badly of him and only ask for Alla's forgiveness لا يجوز علي الميت الا الرحمة.

I myself of course can not confirm if this story is true or a hoax, perhaps people living in Benghazi would have heard about it if it is true and heard about the 3azaa (funeral) by his family, my main problem if it is true is who made this Sons of free Libya, the judge, jury and executioner?? who gave them the right to murder people they disapprove of and claim they did it in the name of Allah? if the story is true then all they did is murder a teenage boy, where is the justice in that? and they committed their crime in a foreign country, did the Libyans and the Egyptian authorities investigate this crime? so now if Libyans going on holiday and decide to do something different like maybe drink Alcohol or commit adultery then they are a target and risk being killed? if this is true then this is another proof of the failure of our society and it wont be long before it is a completely lawless land.

Anyone with information on this please update or confirm.
