William Tereporo Oliver, 33, was last seen in Honolulu on November 1, 2016, in the industrial/maritime Sand Island/Keehi Boat Harbor area. He is described as Hawaiian/Pacific Islander and White/Caucasian, 5 feet 10 inches, about 180 pounds, with brown hair and brown eyes and a tribal tattoo on his collarbone. Family reported he had been experiencing emotional distress before he disappeared.

The Honolulu Police Department opened an investigation under case number 17-011402. Early efforts produced few leads: no surveillance footage or witness accounts have been reported and public appeals struggled without information about what he was wearing when last seen. Community groups have worked to keep the case visible, but investigators cite scarce evidence.

If anyone saw William around Sand Island or Keehi Boat Harbor on or after November 1, 2016, or has information that could help, please come forward.
