Missing Persons Investigation 1-7

Police launch two large-scale searches to find a father of two who goes missing off the WA coast, and a navy veteran lost in hazardous bushland.

A father disappears in croc infested waters and a young girl walks out of her family home and never returns.

When police hit a dead end, a young woman stops at nothing to find her missing brother and new breakthrough forensic techniques may hold the secret to a 30-year-old mystery.
