Kitty is right. Right now this is a problem that's hidden in the shadows, to be ignored and spoken of in whispers with people shaking their heads about poor grandma and the kids - and no one doing anything. The only way to fix that is to get the police and CPS working on it.
CPS is there to give advice, so give them a call and ask for information on what you can do and what resources can be used. Call a local woman's shelter and talk to them about the grandma and the children, get their take on it all from their vantage point. Check for a local mental health unit in your phonebook. Call them and ask them about how to handle the situation, and whether BM can be involuntarily committed for at least observation.
The only way to help the children and grandma is to put a spotlight on what's going on and use the resources available to you.
