DNA evidence reveals family man in Australia was teenage killer who escaped Nebraska jail

William Leslie Arnold killed his parents aged 16 in 1957 and escaped prison ten years later, mystifying authorities until now

William Leslie Arnold was just 16 years old in 1958 when he killed his parents and buried them in the backyard after they refused to let him borrow the family car to take his girlfriend to a drive-in movie showing of The Undead.

Arnold went about his life in and around Omaha, Nebraska, telling everyone - even family members - that his parents had taken a trip. Two weeks later he was arrested, confessed to the killings and led investigators to his parents' makeshift gravesite.
