> "I've spoken to the US Marshals again and they say they have no record of Marcus being in the system. At this point we've been trying to get in contact with Marcus for 18 hours and nobody knows where he's been taken," the person added. "We still don't know why Marcus has been arrested and now we have no idea where in the US he's been taken to and we're extremely concerned for his welfare."<p>What the hell? How does something like this even happen? Surely they can't just take somebody away and keep it a secret?
