She should sue the daughter and the lawyers who took the case for whatever the legal tort of harassment is in this case. Watch the video, dude was a clear threat to her.

I bet if the dead guy watched some random asshole with a knife charging his own daughter, and he had a gun, he would have shot the random, knife charging person.

I get that the daughter doesn't have anything to get but suing the daughter and the lawyer suing her jointly and severally means she can collect from the scumbag lawyer.
