John Emil List was an accountant and World War II and Korea veteran who murdered his wife, three teenage children, and 85-year-old mother in Westfield, New Jersey fifteen days before the Cooper hijacking, withdrew $200,000 from his mother's bank account, and disappeared.[147] He came to the attention of the Cooper task force due to the timing of his disappearance, multiple matches to the hijacker's description, and the reasoning that "a fugitive accused of mass murder has nothing to lose."[137][148] After his capture in 1989, List admitted to murdering his family, but denied any involvement in the Cooper hijacking. While his name continues to crop up in Cooper articles and documentaries, no direct evidence implicates him, and the FBI no longer considers him a suspect.[137] He died in prison in 2008.[149]
