Robert Durst is reportedly dying in prison, and his lawyer is concerned he won't make it to his April trial. The suspected serial killer is facing a first-degree murder charge for the death of his friend Susan Berman, a writer who was shot in her Benedict Canyon home in December 2000.

"We worry about him," one of his attorneys, Donald M. Re, told RadarOnline. "He’s obviously not getting care 24 hours a day, and he's not living with family members who could make sure he is doing OK." He added, "We try to act as surrogate family to go in and visit to make sure he’s all right. But if you watch him as he goes inside the courtroom, you can tell he is losing weight. This has been very hard for him."

Robert — now 74 — and Susan became pals in college, and she told her friends she believed he killed his first wife, Kathie, 29, who went missing in 1982. Although Robert admitted he was the last to see Kathie alive, he disappeared when police reopened the case following Susan’s death. To avoid detection, he disguised himself as a woman and moved to Galveston, TX. In 2001, he confessed to dismembering an elderly neighbor but declared self-defense.

Radar previously reported that an imprisoned jewel thief claimed Robert planned to "turn Hollywood’s red carpets red with celebrity blood" by killing superstars including Barbra Streisand and Julia Roberts. He also confessed that the madman asked him to carry out the A-list massacre using his connections with the New York Mafia and Colombian drug cartels.
