Gilbert Pettigrow, 62, was last seen in Machiasport, Maine, on November 18, 1988. He is described as a white male with gray hair and brown eyes, about 5 feet 10 inches and 160 pounds. His disappearance was unexpected and family said there were no clear signs he planned to leave.

Details about his movements that day are sparse. Searches were conducted and local law enforcement investigated, but no significant leads or physical evidence turned up and the case went cold. The rural, coastal character of Machiasport complicated search efforts, and the family has continued to press for answers.

If anyone in the Machiasport area remembers seeing Gilbert around November 18, 1988, or has information that could help, please come forward.
