Sieu Vei Trang was 13 when she was last seen in Seattle, Washington, on April 3, 1982. She was described as a girl of Asian descent with black hair and brown eyes, about four feet nine inches tall and weighing around 95 pounds.

Those gaps have made public outreach and investigation difficult, and the disappearance remains unsolved.

Anyone who knew Sieu, remembers her from Seattle in 1982, or has information about her disappearance is asked to come forward with what they know.
