OMG - I read this and quickly closed it, but I came back to tell you to tell your friend that I am so sorry for her loss, what a deplorable act, and I can't imagine what you feel after having him stolen and than having to see what happened.
Can you stay somewhere else for awhile. I don't want to scare you, but I don't think you should stay there alone, and I don't think you should leave your little there alone either. How do they know where you live?
This is beyond disgusting
