we try to help you wizcake, but your original post was hhmmm a bit unclear, so we try to come with any ideas and suggestions...
You didn't mention a word about burglary. In this case, since you say it was a burglary, how come you didn't notice it right away? eh? May be it was not a burglary? may be someone that you know very well has done it??
Again, i try to help you, based on the information that you provide..
