<human>: Can you give me a shortened version of the text?

I'll try to keep this as short as possible, and anonymity is important, but I can say that we're Canadian (for any suggestions about law enforcement).

So my girlfriend (let's call her Jane) doesn't live in the same city as her father (let's call him Bob); he's about 3 hours away in a small town, but has to deal with the fact that he has consistently stolen from, and emotionally and physically abused members of her family, and people who have been briefly involved in his life. 

Examples for context:

-Donna (not her real name) is one of Bob's ex-girlfriends, she essentially lives in fear, Bob has emotionally and physically abused her in the past, and has shown no hesitance towards doing it in the future. Donna has a very close relationship with Jane, but really can't see her due to fear that Bob will become jealous and abusive.

-Bob frequently steals prescription medication from his elderly mother to fund whatever legal or illegal activities he engages in.

-Bob has attempted to convince everyone that he has had cancer for the last 10 years, I would describe him as either a hypochondriac or the worst kind of attention seeker.

It has gotten to the point where Jane can't sit back and shrug off what's happening, but there are some problems with calling him out on his bullshit:

-One, or more of the many previous victims of his abuse could become the target of his anger, he has made threats at Donna just for hanging out with Jane without him present.

-Jane's mother (Bob's ex-wife) has been the target of abuse in the past, and could be in potential danger.

Jane really doesn't even want her father involved in her life any more, and while I have suggested notifying law enforcement about potential threats to the various women he has abused, we aren't sure they would be able to do anything.

I'll provide any clarification in the comments, thank you for your consideration.
