Robert Durst, the subject of HBO documentary “The Jinx,” is now under investigation for another decades-old unsolved crime.

Last week Los Angeles County prosecutors filed a murder charge against the real estate heir in the 2000 killing of his friend Susan Berman.

Durst, who was the subject of the HBO documentary series “The Jinx,” made a shocking revelation on the series finale, which aired a day after his arrest: “There it is. You’re caught … What the hell did I do? Killed them all, of course.”

Since then, a number of developments have unfolded in the case.

Durst is under further investigation
Police in Vermont are looking into whether Durst had any connection to the 1971 disappearance of Middlebury College student Lynne Schulze.

“We are aware of the connection between Robert Durst and the disappearance of Lynne Schulze,” Middlebury police said in a statement, according to The LA Times. “We have been aware of this connection for several years and have been working with various outside agencies as we follow this lead.”

Durst has been denied bail
Prosecutors argued Durst was an extreme flight risk and on Monday a New Orleans judge agreed, ruling that Durst will continue to be held without bail. A preliminary hearing on criminal charges will be held on Apr. 2.

Durst was found carrying cash, travel documents and maps
In addition to 446 $100 bills, a “flesh-toned” latex mask with “salt-and-pepper” hair, and travel documents Durst had in his possession at the time of his arrest, investigators later discovered a UPS package was being delivered to the hotel where he was staying containing shoes and an additional $117,000.

Durst was also found with a map picturing Florida and Cuba, lending credence to the theory that he was planning to flee to the island nation, according to veteran attorney Chick Foret.

Durst is off the hook in another case
Oakland police found no evidence linking Durst to the 1997 disappearance of Kristen Modafferi, a student who went missing after finishing work in San Francisco on Jun. 23, 1997. Durst was rumored to be living in the area around that time.

“The Oakland Police Department conducted an investigation with the assistance of the Federal Bureau of Investigation regarding the 1997 disappearance of Kristen Modafferi,” police said in a statement. “The investigation was open and active for several years. At this time we do not have any evidence that indicates Robert Durst was involved in her disappearance.”

A preliminary hearing on criminal charges will be held on Apr. 2.
