In the months leading up to Mary Kennedy's tragic death, Bobby Kennedy's wife beat her husband, threatened suicide in front of her children, ran over the family dog and drank until she passed out.  These are just some of the explosive details in a Newsweek magazine investigation.

The mag had access to the couple's previously sealed divorce papers and also interviewed the housekeeper who, along with Bobby, found Mary hanging in the barn.

Breaking Celebrity News broke the news of Mary Richardson Kennedy's death, and of the debilitating depression she was said to have suffered.

But Bobby's claims of violence had previously been hidden in his divorce documents.

In an affidavit filed as part of their ongoing divorce proceedings, Bobby told the court:

“On May 26, 2011, Mary ran over and killed the dog, Porcia, in the driveway. She had our youngest son Aidan call me to tell me. He was disconsolate and crying. I asked to speak to Mom and Mary came on the phone. She said I should come over and spend the night in my old room with the kids who were distraught. She said she intended to kill herself unless I called off the divorce and unless I promised to recommit to the marriage. She promised that if I came over she would stay in her room and wouldn’t see me or harass me.
