Where did my money go!

Last night I did some late night shopping. I was checking out and I realized all my money had disappeared! It's so stressful when you realise someones stolen off of you, even more so when it's your own kid. I when home to confront the "thief" who goes by the name Normand and he gave me the change that was left of his $30 spending spree. Apparently while I was baking cookies he took the money ,when to the store and spent my money on treats for his "friends". How did he go and come w/o me knowing ? He used the upstairs window! I though he was playing nicely with the half broken Thomas,that he destroyed his brothers! That money could have bought many things, a half a goat for world vision, a new movie, a new christmas tree heck even a hair cut for me! Just once I wish he would do something "text book" style, you know the behaviors that are easy to discipline. What should I do? take Christmas away?buy medical restraints? He always steels off of us and in the last 2 weeks has stolen more then $60 and broken/stolen tons of things that we never get back because he either dismantles them or gives them away . The younger boys have no toys, he's broken them all. I have no "woman" things either as he waists all of my beauty supplies btw, solid shampoo bars are hard to wash off and massage bars don't work that well after it is used as play dough.
