Aunts that lied and destroyed their own siblings marriage

[watching sidelines]

I am a niece and daughter to a bunch of lying cheating aunts and uncles who destroyed another persons relationship. They lied about everything from impersonating, stalking, opening mail, hiding mail, gossiping and making up ****, setting him up with other woman, the list goes on to destroy a long term marriage. They did it all for their own greed and selfishness to destroy someone. The aunt never new what hit her. The sad part is their doing the same thing to their own kids relationships. I tried to show the Uncle the evidence of what they did he wouldn't listen. The worst part is they want all his money and his own wife and kids never even new what happened. I want all the rest of the family to know what deceitful things they have done but I don't know how to get the others to see what they really are. I have texts, pics, their notes and other proof but don't know how to get the better half of the family to listen. This was so wrong. Anyone know how justice can be served so they cant keep doing it.....
