Some strange sh*t, what do I make of it? *warning, long*

[slickpoppa]

I think one key to solving this mystery is figuring out how the thief (if it was not the girl) got into your house. Tells us all the possible entry points of your house and whether or not you are sure that they were locked. If all of your doors were definitely locked, then the thief could have still picked a lock, but he would definitely not lock the door as he left. So can you confirm whether all your doors were locked after you discovered the burglary? (I think it is amazing that the police were not asking these questions)
