Convicted killer Robert Durst has died at age 78, four months after a jury found him guilty of killing his close friend Susan Berman.

As the New Yotk Times reports, Durst went into cardiac arrest while serving his sentence at the California Health Care Facility in Stockton, California. Durst had been suffering from numerous health issues during his trial, including bladder cancer.

Durst’s attorney Chip Lewis confirmed the death of the heir to a real estate dynasty, noting that his client’s health had worsened since contracting Covid-19 shortly after his conviction.

At Durst’s second murder trial, prosecutors argued that Durst killed Berman, a longtime close friend, in 2000 because she knew details about the unsolved disappearance of his wife Kathie Durst, who vanished in 1982. Her body has never been found, and Durst’s death increases the likelihood that her disappearance may never be solved.

A year after Berman’s death, Durst fatally shot Morris Black, his neighbor in Galveston, Texas, but was acquitted on grounds of self-defense, even though he dismembered Black’s body. As the New York Times notes, Durst skipped bail following his arrest for Black’s murder and was apprehended after he was caught stealing a sandwich from a supermarket.

At the time, Durst had $37,000 cash in his car.
