-- In the mystery surrounding the 1982 disappearance of Kathie Durst, the wife of real estate heir Robert Durst, her friends had no question who was involved.
Four of Kathie's friends interviewed by ABC News in 2001 were all convinced that Robert Durst was connected to their friend's disappearance because she had told them as much.
In the months and weeks leading up to her Jan. 31, 1982 disappearance, Kathie Durst told friends like Eleanor Schwank that "if anything ever happens to me, don't let Bobby get away with it."
Durst was never charged in connection to his wife's disappearance, and even though her body was never found, she was declared dead in 2001.
Archival footage shows interviews with Kathie's friends including Gilberte Najamy, who was the last person to see Kathie before she left to meet Robert.
"The last conversation that I had with Kathie was a very powerful conversation and as she was leaving my house, she turned to me and said 'Gilberte, promise me if something happens to me you'll check it out. I'm afraid of what Bobby might do,'" Najamy told ABC News in 2001.
Durst has now been charged with the 2000 murder of his friend Susan Berman who police believe was about to meet with investigators about Kathie's disappearance days after she was found dead.
