I haven't read that. He is supposedly someone van der Sloot is associated with. Not sure how closely, it was said "runs around with." Supposedly 26 yrs old, but another mentioned perhaps younger. Only the initials SGC have been given as identification for this person. I believe that is what has been said so far.
Could SGC stand for something other than a name? I'm seeing "SGC" on travel and cruise websites but can't find what SGC stands for.
