Billy Oliveira: The Nāhiku Accounts

Home, family testimony and differently dated reports frame the public record.

Abstract

NamUs MP34387 lists July 13, 2015 as Billy Oliveira’s last contact in Nāhiku.1

The Home Account

Its narrative attributes to his grandmother an approaching vehicle and Oliveira going outside. The entry does not establish who was in the vehicle or where he went.1

The Family Context

In Wendy Osher’s July 24, 2015 Maui Now report, cousin Amy Yamada describes Oliveira and his grandmother looking after each other. She said he usually told his grandmother when he was leaving.2

Published Dates

Maui Now’s January 19, 2017 report places the last sighting in Nāhiku on July 14, 2015 and gives July 16 as the report date.3

Its January 4, 2024 roundup uses July 13 for the residence observation and July 16 for the report, giving case 15-028924.4

The date difference remains unresolved here; these reports do not provide the underlying observation statements.3,4

Later Record Details

Osher’s report attributes foot searches from July 16 through 19, 2015 to Yamada’s account of Maui Search and Rescue’s work. Yamada described no findings in the searched area.2

Osher also attributed a then-current police assessment of no suspected foul play to Lieutenant William Juan. That dated assessment does not establish what happened.2

The January 2017 report attributes an ongoing search to a Maui Police update. That statement describes the investigation at that time.3

The 2024 roundup includes Oliveira among cases highlighted by the Cold Case / Missing Person Detail unit. Its appeal is not a new observation.4

Scope and Method
