David L. Porter, 23, disappeared from Honolulu in early November 1976 and is considered a suspicious, unresolved case. Friends called him Boogie; the last confirmed sighting was at his mother’s home late afternoon on November 3, 1976. He left behind his dog, and did not touch his bank account after vanishing, details that family and friends say made a planned departure unlikely.

Porter’s white 1965 Volkswagen Beetle was seen at his mother’s home about 8:00 a.m. on November 4, then went missing that same morning. Weeks later the car was found abandoned near Kaumoku Street at Mariners Ridge, reportedly left between November 7 and November 11. The vehicle had been wiped clean of fingerprints and Porter’s swim fins were in the trunk; there was no sign of him at the scene and no clear trail away.

Porter’s father had died of cancer just weeks before the disappearance, but his brother said Porter did not seem unusually depressed. No named suspect, arrest, charge, trial, or conviction has been reported in connection with his disappearance. Did anyone who knew Porter or his routines in 1976 see anything that might help explain what happened?
