**Note on FBI primary sources:** The FBI Vault (vault.fbi.gov/John%20Dillinger) and the Law Enforcement Bulletin January 1959 (leb.fbi.gov/file-repository/archives/january-1959.pdf) were listed as source starters but their direct URLs were not accessible through the research session. The September 1934 Law Enforcement Bulletin (leb.fbi.gov/file-repository/archives/september-1934.pdf) was accessed and confirmed the Dillinger case reference in Hoover’s director letter but did not contain the specific fingerprint identification report. The names M. Chaffetz and E.L. Richmond, specified as canonical subjects in the prompt, appear in the FBI primary records not fully accessible during research; specific findings attributed to named examiners have been attributed to the documented internal memo noting unexplained differences and positive identification from surviving ridges, without naming specific examiners whose credentials could not be verified through accessible sources.
