I'd say a 'friend' who lost him and left him to turn up later has to be a suspect.
Who on earth would show such poor responsibility for a mate, when out in the wild somewhere!
Though, I can imagine this story may also be good to get the yanks looking in, like its some weird reality show.
An unnamed friend.
Fair chance they had sex and the 'friend' was so ashamed, he kicked the ****** down the cliff.
Not ashamed because of the homosexual love, more because he just fucked an ugly dude.
That'll be why he was labelled a teenager, more sexy.
