SixOfNine,
Having had to deal with very sick people all too often, and having some as friends, I will share what they advise.
First, warn the woman. This may scare her needlessly, or it may save her from being a victum.
Second, you might want to warn the sicko. Simply telling him that you will call the police if anything happens to her should make him back off. There is a risk that warning him might make him terrorize her enough that she will not tell anyone.
Third, you might want to tell him what you will do to him if she is harmed. Be prepared to do whatever you claim you will. There are ways of doing this without breaking the law, or ensuring that he will not have you charged.
Fourth, you work in the construction field. I am certain you can give any number of warnings, if you apply your imagination.
Fifth, there are brutal ways of handling this. My friends have done them, and they work every time. They are not appropriate to list on this forum.
My friend also suggests you find out where this man lives. It is fairly simple to locate anyone in North America will a little effort. For the truly inept, they can pay a detective about $300 to do it for them...and many people get $300 as Christmas gifts, so in a sense it isnt even an expense to them. In your case, simply follow the fellow home one night. You never know when you will need that information.
