Kathleen Durst was a fourth-year student at Albert Einstein College of Medicine in the Bronx when she was reported missing, just about four months from graduation. When Kathleen first vanished, her husband told the police he last spoke to her by phone while she was in Manhattan and he was in the family cottage in South Salem. He told police he last saw his wife at the Katonah train station, where she was planning to board a 21.15 train to Manhattan.

On February 4, he received a call from the supervisor at her medical school saying that she had failed to show up for class all week. The supervisor said he had last heard from her on February 1 when she called to say she was ill and would not be attending classes that day. the husband reported Kathy as missing the next day. Investigators now believe that Kathy Durst may have never left South Salem. (Information retrieved from NamUs.gov)
