Yim Yeung Tsui, known as Jimmy, was last seen the morning of August 26, 1998, in New Hyde Park, New York. He was 20 and about to begin his third year at Stony Brook University. That morning his sister briefly saw him sleeping in bed before she left for work; he has not been seen since.

Born in southern China, Yim and his family moved to the United States in 1988. Family members describe him as shy and having struggled with language barriers. After he disappeared the family received a letter saying he had been expelled from Stony Brook for poor academic performance. His parents were visiting relatives in Australia at the time and his older sister was living in Hawaii. The family searched places he liked, including Port Washington beaches and Manhattan’s Chinatown. The Nassau County Police Department continues to investigate; there have been no confirmed sightings or substantial leads, and DNA testing in 2011 excluded Yim from a body found on Gilgo Beach.

Does anyone who knew Yim or saw him in New Hyde Park or the surrounding areas in August 1998 have information that could help his family?
