Oded Gordon was 21 and living at Plowshare Farm in Greenfield, New Hampshire, a program for young adults with developmental disabilities, when he vanished on May 12, 1989. That day he was working in the garden, became annoyed by flies, and walked off; caregivers thought he might sit in a car but he never returned. He had no identification, coat, or money.

Search dogs followed his scent along Route 31 for about three miles, and investigators say that suggests he may have been picked up by a passing vehicle. There were later unconfirmed reports of sightings in nearby Merrimack, New Hampshire, and Fitchburg, Massachusetts, including a man’s claim that he picked up Gordon as a hitchhiker and left him at a donut shop in Fitchburg. Gordon had scoliosis that caused a hunched posture, communicated at about a seven-year-old level, and was described by his mother as extremely fearful.

His original home state was New York, and investigators considered the possibility he tried to return there. His whereabouts remain unknown. If anyone knew Oded, saw him in May 1989, or has information about travel along Route 31 or those reported sightings, please share what is known.
