Jill Biden’s first husband, Bill Stevenson, claims he is the “missing link” in the decades-long mystery of Kathie Durst, who disappeared in 1982. Stevenson admitted to having an affair with Durst ten days before she went missing, and accused her “crazy” husband, Robert Durst, of her murder.

The bombshell accusation comes as 78-year-old Robert Durst stands trial in California for a separate murder. Bill Stevenson claims he is coming clean, and though he hasn’t shared the story publicly before, believes it’s the right thing to do before Durst succumbs to his failing health. Stevenson claims that “I’m the missing link in this case.”

Bill Stevenson and Kathie Durst were lifelong pals, having met when they were young, and spent time together because their parents were good friends. Stevenson explained that he watched Kathie “grow up” and thought “she was that cool little sister” at one point. He then “watched her grow up to be a beautiful young woman.”

In 1974, during his marriage to Jill Biden, both Stevenson and his wife had Kathie and Robert Durst over for a dinner. Stevenson claimed that Jill and Kathie “hit it off” because they were “both very smart” people.”

Despite the good vibes between wives, Stevenson remembers walking in on Robert Durst, “talking to himself in my garage. To me, it was like, ‘oh my god.’” Those red flags didn’t set off enough of an alarm, because it wasn’t until years later after Bill and Jill got divorced, that Stevenson realized Durst was a problem.

In 1981, Kathie Durst began confiding in Stevenson, and admitted that she was “having a real problem with Robert.” She told Stevenson “I’m scared to death.”

In those decades-old conversations, Kathie Durst claimed that her husband had gotten violent, but she couldn’t tell anyone since there was no one she could trust. “I don’t know why she picked me but I’m glad she did,” Bill Stevenson told Long Island’s News 12 during an interview. “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 claims he and Kathie saw each other five times between 1981 and 1982, and that he even stayed at Kathie’s apartment in New York City. At some point it became romantic.

“She was in this silk nightie,” Stevenson 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.”

Bill Stevenson continued, recalling that “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.’”

According to Stevenson, Kathie had screamed at her husband, claiming she was “moving to Delaware” and that she was done. “People have to understand, this guy is a monster,” Stevenson said. “I saw it in his eyes.”

In 1982, ten days after their final meetup, Bill Stevenson heard that Kathie Durst had gone missing, and didn’t believe Robert’s story that he had gone straight to the police. “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.”

Bill Stevenson is adamant that Robert Durst killed his wife. “Absolutely,” Stevenson said, and explained that the affair “would have driven him crazy.”

“I don’t feel guilty about that,” Stevenson admitted. “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.”

Robert Durst is currently on trial for the 2000 murder of his friend, Susan Berman. Durst is accused of murdering Berman to keep her from telling police what she knew about Kathie’s disappearance. Durst is also accused of murdering Morris Black, his close friend. Robert Durst’s lawyer was adamant that Durst did not kill his wife, and said he needed to watch Stevenson’s interview before he could react to the allegations.

During his interview, Stevenson said that he believes Kathie Durst is looking down from heaven, saying that “I cannot believe this story is finally going to be told.” Stevenson’s story is currently in question, especially since the NYPD does not keep visitor logs dating back to the 1980s when he claims he went to the 19th precinct about Kathie’s disappearance.

According to Kathie Durst’s family, Kathie did reveal that she was seeing Bill Stevenson before she went missing, though no further details about the exchanges were referenced.

Bill Stevenson previously claimed that Jill and Joe Biden had an affair when Jill was still married to him, an accusation that the President and First Lady vehemently denied.
