The inquest served multiple purposes. It established the legal cause of death. It established the identity of the decedent. And it addressed the central legal question raised by the shooting: was the killing of John Dillinger legally justified?
The identity finding drew on multiple lines of evidence: the fingerprint comparison, Audrey Hancock’s identification, and the circumstantial evidence placing Dillinger at the Biograph Theater that evening — Anna Sage’s confirmation, the agents’ recognition of him, and the fact that the shooting occurred at the time and location Sage had described.
The justification finding was straightforward from the FBI’s perspective. The agents who had shot Dillinger were authorized law enforcement officers pursuing a federal fugitive who had been designated a priority target. When Dillinger reached for his weapon, the agents responded. The legal framework of the time, particularly in a context where a federal fugitive was drawing a firearm against law enforcement, provided clear justification for the use of deadly force.
The inquest returned a finding that the death was justified. The official record closed the central legal questions that night.

## The FBI’s Scientific Interpretation of the Dillinger Case
The FBI’s public and institutional handling of the Dillinger fingerprint case evolved in the years following 1934. The immediate presentation emphasized the successful identification. The subsequent institutional analysis focused on what the case demonstrated about the science.
In the Bureau’s interpretation, the Dillinger case was evidence for three connected propositions. First, that fingerprint evidence is durable — not easily defeated by the methods available to criminals. Second, that the FBI’s identification infrastructure was capable of handling forensic challenges that surface-level alteration created. Third, that attempts to defeat fingerprint identification through available means were ultimately futile and therefore irrational.
