Peter Denis O’Brien, 44 and originally from New Zealand, was last seen April 2, 2009, in Boise, Idaho. He dropped his two young sons at his ex-wife’s house that day and planned to pick them up two days later but never returned. His apartment was found unlocked with wallet, credit cards, keys, phone, and clothing left behind; his laptop and passport were missing.

O’Brien had moved to Boise from Los Angeles about seven weeks before his disappearance to be closer to his children. Family and acquaintances describe him as a loving father who enjoyed hiking, especially at Camel’s Back Park, and who liked music and cooking. Investigators checked the hiking theory and considered suicide but found no evidence supporting either, and there is no record of his passport being used. His whereabouts remain unknown despite an extensive investigation.

If anyone saw Peter around Boise in early April 2009 or has information about his laptop, passport, or movements after April 2, please come forward.
