Interesting story in The Star today.

Some kid - addicted to CoD4 - runs away from home because his dad takes his XBox 360 away.

The parents suspect the boy has been lured away and kidnapped by evil gamers from the internets.

I’m willing to be that the son is off somewhere, hanging out at a friend’s place until this whole thing blows over. Is it possible to log in to an XBox Live account from another system? See if he has logged on. Maybe he is at a friend’s house playing CoD4 regardless.
