>>/41365/  Here is an interesting review of Mrs. Corsi's house cleaning service.  The workers broke the burglar alarm?  Maybe the disconnected it so they could come back later and rob the house.  They don't just clean houses they also do commercial cleaning and would have access to a lot of businesses as well.
