Investigator: Joseph Naso Idolized Caryl Chessman
A retired FBI task force investigator, Ken Mains, says convicted serial killer Joseph Naso may have been paying homage to executed inmate Caryl Chessman when he targeted victims whose first and last names shared initials. The claim — highlighted in a new Oxygen docuseries 'Death Row Confidential' and supported by a 300-page dossier compiled by fellow inmate William Noguera — ties Naso’s known murders (1977–1994) and his 2013 conviction to possible broader cold-case leads.
