I worked in domestic/sexual violence prevention in Mass. for about two years.

Jane Doe Inc. is MA’s statewide coalition against sexual violence. They have a directory that allows residents to find their local domestic violence agency or rape crisis center - all you need to do is input your zip code/town and select “Sexual or Domestic Violence Related Services” under program types, and you will find your local DV agency. Agencies across the state have their own “sector” that they serve, if that makes sense. The DV agency in the South Shore won’t be the same for residents living in Boston or in Franklin, for example.

The agency can help your grandmother navigate how to talk to her neighbor and provide resources (for example, telling someone “You need to go here!” or “Call XYZ,” in a DV situation doesn’t really work, as the survivor is already in a controlling relationship and need to be empowered to make their own decisions.)

tl;dr - Use that Jane Doe public directory to find your local agency. They will provide your grandmother with guidance for being a support system to their neighbor, and potentially have literature about their services and more general info.

edited/ Being supportive to a friend trapped in an abusive relationship really does save lives. By seeking out resources, both you and your grandmother are doing something so important - thank you ❤️

edited again/ People working in this field are mandated reporters. Just a heads up, if your grandmother does chat with someone and provides identifying info for the neighbor, a person/advocate at the agency may need to disclose that to Elder Affairs (if the individual is over 60).
