Should I Talk to My Daughters Attorney?

My daughter married a great guy. He feel "head over heels" for her even tho she has 4 different children by 4 different guys. She sits on her butt & collects child support but we watch hardly any go towards our grand children. Well now the new guy she married (I will call him "John") has a VERY good job. He stays home & watches her kids while she runs around spending money. We know he is hurt that he is so ignored by her & feels she just only wants his money & a built in babysitter. The problem now is that he took her on a beautiful first anniversary trip. It was for 5 days & my daughter went through nearly $15,000! She got her kids all clothes plus herself & lots of very nice jewelry (the ring was over $3000). John got nothing. The last day he took her on a helicopter ride, a wonderful lunch, more shopping & a beautiful romantic dinner. They both drank. When they returned to the cabin rental (it was a beautiful place) she began to get mad over something that neither one can remember exactly what it was about. She has always hit. She began hitting John right after they married & at one point took a Fiesta stoneware dinner plate & cracked him over the side of his head one night. The dish shattered. He refused to call the police & forgave her. The hits & slaps John took were horrible over time & he told his parents & me that he was humiliated to have people ever find out of the beatings he has taken over the months. The last night in the cabin she fought with him & while he sat on the bed she punched him several times in the head & then threw up to him about a guy she has been talking to over the phone. We had all known this because she hid his call # under a girls name but one night John was up & heard her cell go off. He called back the # & a guy answered. John lost it after being the best he could be to her & spending on her, having her punching him & the worst of it being told about another guy John reached back & hit her in the face. She then jumped up & ran out to another nearby cabin. The police were called & John was thrown to the ground, kicked in the head & ribs, taken inside the cabin & told to write down the "beating" he had done to her. He was not read his rights & was told by one of the officers that they have no cameras on their police cars so the kicks he received no one would know about. John was scared to death so wrote down how the police "prompted" him. Now John & my daughter are getting divorced. She went to court & told the prosecutors office that John always beat her! John is looking at 11 mos. 29 days in jail, losing his great job, & he has full custody of his 4 children from his first marriage & will lose them. My daughter is doing this to him because she told her friend (who told me) that in the divorce decree he is giving her nothing for the 11 1/2 mos of marriage. She said her goal is to make sure he has no life at all! She now wants family members to tell lies about John & it's so sad that they are agreeing to lie on her behalf! I will NOT! She said she doesn't need me to anyway because she has enough people. She also lied to John's brother & his brother felt sorry for her so he said he would testify against his own brother! Should I let the prosecutors office know what she is doing? This happened in Tennessee & we live in another state. PLEASE help me! I am sick to my stomach! Thank you so much for your time.
