Who Was DB Cooper, the Man Who Stole $1.4 Million and Vanished Without a Trace?

John List was a convicted murderer who killed his wife, three children, and 84-year-old mother at their home in Westfield, NJ, on Nov. 9, 1971. List withdrew $200,000 from his mother's bank account and disappeared soon after, evading police for nearly 18 years.

Investigators on the DB Cooper case primarily considered him a suspect for the timing of his disappearance and his resemblance to the hijacker's description. After his arrest in 1989, List admitted to murdering his family but denied any involvement in the DB Cooper case. Police were unable to find any substantial evidence implicating List in the hijacking, and the FBI no longer considers him a suspect. List died in 2008.
