Gregory T. Larson was 63 and living in Seattle when he was last heard from on December 29, 1989. During a phone call to a friend he said he needed to leave for New York for a few days and expected to be back shortly. Friends found his sudden silence out of character, and no further contact was made.

Larson is described as a Caucasian male, 5 feet 9 inches and about 210 pounds, with graying hair, glasses and a missing right eye for which he did not wear a prosthetic. The Seattle Police Department opened a missing person case on January 1, 1990. Investigators were unable to confirm whether he actually traveled to New York or find evidence that he reached that destination, leaving the timeline and location of his disappearance unclear.

Anyone who knew Gregory, his travel plans at the end of December 1989, or who may have seen him in Seattle or New York around that time is asked to come forward with information.
