sorry to hear about this harassment - I think we need better laws covering cyber stalking - this is a major crime in my opinion - someone is attacking your family privacy as well as causing grave anxiety - I'm disappointed by the police response. They think if there's no blood on the floor, it's not that major. So short-sighted.
The laws are actually pretty good now. If I was able to catch this guy, it would be pretty serious. It is a major crime. It's just too bad the resources are not available to people like me. But I'll find a way.....
I hope you find someone who can help - in the meantime, a few outdoor cameras and motion lights will deter intruders both day and night - It's not too great an expense for the peace of mind they provide.
