On a fall day in New York, 28-year-old Kristine Kupka, a bright and ambitious honors student at Baruch College, disappeared from her Brooklyn home. It was October 24, 1998, and Kristine, who was five months pregnant, was last seen leaving her residence with her former chemistry instructor, Darshanand 'Rudy' Persaud. The two had been involved in an affair, and he was the father of her unborn child. The relationship was troubled; Persaud was married and had allegedly urged Kristine to have an abortion, a suggestion she refused. In the time leading up to her disappearance, Kristine had confided in friends that she was frightened of Persaud. On the day she vanished, she left a message for her sister stating she was going with Persaud to see a new apartment he was supposedly renting for her. She left without a coat or many personal belongings and was never heard from again.
The investigation almost immediately centered on Darshanand Persaud, the last person known to have seen Kristine. When questioned by police—in what would be his only interview—Persaud offered a different account of their last hours together. He claimed he drove Kristine to a shopping mall, waited in the car while she shopped, and then dropped her off a couple of blocks from her home. However, he could not name the mall they had supposedly visited. Police could not corroborate his story, and he hired a lawyer shortly after the interview, refusing further communication. Although authorities noted he had a clear motive, there was not enough physical evidence to directly link him to her disappearance. Years later, in 2010, investigators received a tip and dug up the basement of a Queens shop once owned by a relative of Persaud's, but the search yielded no results.
Kristine was described by her loved ones as a strong-willed and intelligent woman who was looking forward to becoming a mother. She was a philosophy major with plans to attend law school to become a civil rights attorney focusing on women's issues. In the years since she vanished, her family, particularly her sister Kathy, has worked tirelessly to keep her case in the public eye, even hiring a private investigator. The overview of this case reveals a heartbreaking story of a young woman with a promising future whose life was cut short under deeply suspicious circumstances. While her boyfriend remains the primary person of interest, the lack of concrete evidence has prevented any charges from being filed, leaving the case cold and her family without answers or justice.Last Seen: Oct 24, 1998
