Jason's (ex?) girlfriend's facebook page was just updated. Cover photo changed to one which doesnt include jason, and no longer shows being "in relationship".
Thing to keep in mind, the house Jason and Melissa lived in is owned by her parents. So its probably safe to assume Jason's current whereabouts are unknown.
I hope he will suffer whole his life if he does not return EVERY CUSTOMER everything he stole from them. And I really hope someone out there will pay him a visit to "talk" with him.
