Jill Biden's ex-husband Bill Stevenson has shockingly claimed that he slept with Robert Durst's murdered wife Kathleen just days before she vanished. He is now convinced he may be the "missing link in the case" that drove the suspected serial killer "crazy."

Stevenson was married to Jill Biden between 1970 and 1975. Towards the end of their marriage, she started working for Joe Biden when he was a Senator. The duo tied the knot in 1977, five years before Kathleen Durst mysteriously went missing in 1982. Stevenson has previously accused his ex-wife of having an affair with the future president while she was still married to him. He has now claimed he was childhood friends with Kathleen, the Daily Mail reported.

Stevenson made the claims during an interview with Long Island's News 12 on Thursday, July 8, saying he and Jill hosted Robert and Kathleen Durst at their home in 1974. He recalled Robert behaving rather strangely, talking to himself in the garage.

In 1982, Kathleen allegedly confided in Stevenson that she was scared of Robert. According to him, Kathleen spent the night with him at her New York City apartment, and that is when their friendship became intimate. The next day, Robert allegedly showed up at the residence and began "pounding on the door" before slamming a wad of rolled-up cash in Kathleen's face. She vanished ten days later, per the newspaper.

Stevenson thinks Robert, who has never been charged over accusations that he killed his wife, was driven to end her life after discovering their affair. "This is something that has to be righted. I was together with them and he went crazy. I feel like I'm the missing link in this case," he said.

Jill Biden's ex noted that he had watched Kathleen "grow up into a beautiful young woman" as they were family friends since childhood. "She was that cool little sister - I watched her grow up to be a beautiful young woman," he said, before claiming he and Jill hosted Kathleen and Robert Durst at their home in 1974.

According to him, Jill and Kathleen "hit it off" immediately. "Both very smart, they're similar people. At that age. It was hard not to hit it off," he said. "I remember him talking to himself in my garage. To me, it was like, 'oh my god.'"

Once his marriage to Jill had broken up and she tied the knot with Joe, Kathleen allegedly began confiding in Stevenson.

"She said I'm having a real problem with Robert and I'm scared to death," he recounted. "She said he was being violent with her. At that point, she couldn't trust anybody around her that knew Robert. I don't know why she picked me but I'm glad she did. But I do feel that I let her down. I look back at those last two months and go, 'what could I have done differently.'"

Stevenson said he visited Kathleen at least five times between 1981 and 1982. It was allegedly during one of these visits that their relationship became romantic. "She was in this silk nightie," he recalled. "Nothing was said. She grabbed my hand, led me back to the bedroom. We closed the door and life changed for both of us. Totally unexpected. Beautiful night. No regrets."

"The next thing I realize we hear pounding on the door, it's 7.30 in the morning, she runs out of the bedroom, runs back in, and says it's bob," Stevenson continued. "I jumped up and ran out, he screams something and he had a wad of cash and he hit her right in the face with it. He started yelling: 'Kathleen, this isn't going to happen.' She starts yelling: 'I'm moving to Delaware! I'm done! We're done!' I'm like sitting there, I'm in shock. People have to understand, this guy is a monster. I saw it in his eyes."

Kathleen Durst was reported missing ten days later. Stevenson says he immediately alerted the authorities about what he knew, but no one followed up on his report, allegedly. "I got in my car, went to the 19th precinct - literally within 24 hours - and said: 'Nuh-uh. He killed her.' [The cop] wrote a couple of things down, and said: 'we'll get back to you.' I never heard a word back from them."

Stevenson was asked if he thought his alleged affair with Kathleen had anything to do with her murder.

"Absolutely - it would have driven him crazy. I don't feel guilty about that," he responded. "He was abusing her and she wanted out. And I feel like if something happened wonderful at the end of her life, I hope this was it. I'm sorry. I just hope that you know she had the same thoughts at the end there," he added. In the past, Stevenson has also claimed Jill and Joe had had an affair when she was still married to him. However, his claims have been denied by both the President and the First Lady.
