SHOCKING POLICE DOCUMENTS detail the desperate last hours of MARY RICHARDSON KENENDY as she begged estranged hubby RFK, JR to help her — he refused and she killed herself!

The papers, released by the Bedford Police Department, include a statement from Robert Kennedy Jr., given one day after Mary's body was discovered hanging in the barn at the family home.

"She told me she was sorry for everything. She said I was right about everything, and everything was her fault. She then told me she needed me to take care of her," he reportedly said, recalling a phone conversation he had had with Mary on May 15.

The caretaker of the family estate told police that Kennedy told her that he couldn't help Mary because "she doesn't want to help herself," according to the New York Daily News.

As The ENQUIRER previously reported Mary, who had battled alcoholism throughout her life, had appeared "depressed and despondent" shortly before her suicide.

Mary was struggling to come to terms with the end of their marriage, despite Robert having filed for divorce two years previously, and that the couple was heading to trial. Meanwhile Bobby had made no secret of the fact that he was dating actress Cheryl Hines

"It was very tough for Mary to deal with Robert dating someone else," a source told

"And it really didn't help that the new woman is a celebrity. She would see photos of the two of them together and it would drive her nuts.

“I think, deep down, she had still harbored a belief they would get back together but it had recently become blindingly clear that wasn't to be."
