My son is 15 and does the same thing.  Has been for awhile.  Won't own up to anything, even when I catch him,  I told him I will blame you for everything, when something is missing, I say it was him,  prove me differently.  Honestly I don't know how to get them to stop.  I keep my room locked, have thought about puttin a lock on the panrty.  He is not allowed to be home alone.  If we go somewhere he has to come with us or leave the house and doesn't get a key.   

Kids are very good and making us believe it wasn't them who did it.  My son is getting better, I think with time they grow up.
