Kathleen McCormack Durst was a 29-year-old medical student who disappeared from South Salem, New York, on January 31, 1982. The night she was last seen she attended a dinner party in Connecticut and left visibly upset after receiving a call from her husband.

Robert Durst told investigators he dropped Kathleen at a train station so she could return to Manhattan for classes the next day, but no one corroborated seeing her there and his account changed over time. He reported her missing five days later only after the medical school contacted him about her unexplained absences; a woman claiming to be Kathleen had phoned the school the day after she vanished to say she was ill. Investigators also noted inconsistencies in Durst’s statements and that he had begun disposing of Kathleen’s belongings.

The case went cold for years, remaining unsolved and without a body. Does anyone have information about Kathleen’s movements in late January 1982 or recall seeing her after that dinner in Connecticut?
