Robert Durst is credibly linked to several other murders, that they didn't even get around to discussing on The Jinx.
"Days after the Berman murder, police were reportedly examining connections between Durst and disappearances of 17-year-old Lynne Schulze from Middlebury, Vermont,and 16-year-old Karen Mitchell from Eureka, California. Investigators are also looking into a possible connection with the disappearance of 18-year-old Kristen Modafferi, last seen in San Francisco in 1997.
Schulze, a Middlebury College freshman, visited Durst's health food store on December 10, 1971, the day she disappeared, and was last seen that afternoon near a bus stop across from the store. ...credit card records placed Durst in Eureka on November 25, 1997, the day Mitchell vanished. Mitchell may have volunteered in a homeless shelter that Durst frequented; Durst, dressed in women's clothing, had visited the Eureka shoe store owned by Mitchell's aunt. Mitchell was last seen walking to work from her aunt's store and possibly speaking to someone in a stopped car; a witness sketch of Mitchell's presumed abductor resembles Durst."
