    Details of Disappearance

    Collman's parents realized he was missing when his boss called them on April 3, 1979 to say he hadn't shown up for work. He lived with his parents in a basement bedroom and worked second shift at a Model Box factory off Route 47 and Cannonball Road. He has never been heard from again.

    Little information is available in Collman's case, but his parents said he was very close to his younger brothers and would never have willingly gone for this long without contacting them. His parents had him declared legally dead after his disappearance and placed a stone for him at the cemetery. Foul play is possible in Collman's case; it remains unsolved.
