Hank Roberts Sr., 71, disappeared from Kalapana on the Big Island of Hawaii after a day that included a reported domestic disturbance at the Puna Palisades home he shared with his daughter. Police visited the residence between 10:00 and 10:30 a.m. on March 18, 2004, but made no arrests. A neighbor later saw Roberts standing alone at the subdivision entrance about 4:30 p.m.; that is the last confirmed sighting. His car remained at the house, noted as unusual for a man who reportedly drove into nearby Pahoa Village every day.

Roberts was described as a Caucasian male, 5 feet 8 inches, about 160 pounds, with graying hair and blue eyes. He had lived on Maui previously, where he owned a business in Paia, and also lived in Miami Beach earlier in life. He was active in local affairs, frequently writing letters to the Tribune-Herald and speaking at council meetings on issues like smoking bans and marijuana eradication.

Investigators say they cannot rule out foul play or suicide, though they considered foul play unlikely; the family believes foul play. Extensive searches, including canine units, turned up no clues and the investigation has since gone cold. Did anyone in Kalapana or Pahoa remember seeing Hank around March 18, 2004, or know of contacts that could help his family?
