My Mom Was Murdered- Do I Have Any Legal Recourse?

My mom was attacked by a woman with a hammer on August 31. She passed from her injuries September 5. The woman who killed her had been in jail the weekend before for stabbing someone she was either currently or formerly in a romantic relationship. Her bond was $10,000 and she bonded out on August 28. During the time she was out she killed another man as well.

What I would like to know is if there is anyone I could sue? Her family appears to have no assets, but I would like to make life difficult for them. She has some sort of mental illness (her attorney has said schizophrenia, bi-polar disorder and/or borderline personality disorder- unknown if any of that is true). If her family knew this and bailed her out of jail without having some sort of plan to keep her from harming others, well, I find them just as culpable.

Is there a way to sue the county judge for making the bail so low? Again, I’m not looking to make a paycheck but trying to ensure this doesn’t happen to anyone else.

I live in a deeeeeeeply red state that provides little health care coverage for its most vulnerable citizens and especially not mental health care. I personally had a difficult time finding the appropriate care for myself after this happened and I’m well educated, relatively affluent, and have great medical insurance. Can I sue the state over this to make a point that they need to do better?

I think the answer to the above is probably no.

If that is the case, would I legally be in any trouble for sending her family large glossy photos of my mother beaten to hell, her face so swollen and bruised that she was unrecognizable? Because if this is what I have to live with, why shouldn’t they?

Could I take out a billboard close to their church and workplaces with photos of my mom saying “Look what their daughter did”?

I’m actually considering both of these options.

I know this is grief and I am getting appropriate mental health care, but I’m so angry that this crazy woman (who my mom didn’t even know) took my mom away from me and someone needs to suffer the way I am.

What are my options?
