Jeffery Allen Henderson, known to some as Jeff or Tattoo Jeff, disappeared from the South Kona area of the Big Island of Hawaii on August 13, 2001. He was 48 at the time, described as a Caucasian male about 6 feet tall and 180 pounds, with brown hair, blue eyes, a mustache, reading glasses, numerous upper-body tattoos, a skin graft scar on one leg, and his upper front teeth extracted.

Authorities called the circumstances suspicious. He had not collected any Social Security benefits after he was last seen and had no known contact with friends or family, which investigators regarded as a notable break from his normal routine. Few public details have been released and the case has stayed open with periodic appeals for information.

If anyone in South Kona in August 2001 remembers Jeffery, his routines, or possible sightings after August 13, any details could help the ongoing inquiry.
