The Biograph’s success was partly skill, partly better intelligence (a close informant rather than a distant tip), and partly the kind of contingent factors that determine outcomes in high-stakes physical confrontations. It did not eliminate the possibility of failure in future operations; it demonstrated what a well-staged operation could look like.

## The Gravity of October 1933: What the Lima Killing Changed
Of all the deaths associated with the Dillinger network, the October 12, 1933 killing of Sheriff Jess Sarber deserves particular attention, because it was the event that most decisively raised the stakes of the entire case.
Sarber was sixty years old. He had been elected sheriff of Allen County, Ohio, and was running the Lima jail with a skeleton staff. When the men who came to free Dillinger presented themselves as state officials from Indiana there to pick up the prisoner, Sarber asked to see their credentials.
What happened next — the confrontation, the gunshots, the sheriff’s death — was the moment when the Dillinger network stopped being a series of property crimes and became a series of property crimes plus murder. Sarber had done exactly what a conscientious law enforcement officer should do: verified the identity of people claiming authority to remove a prisoner. He was killed for it.
The impact on the investigation and eventual prosecution of the case was substantial. Indiana now had to pursue the people who had killed Sarber, as well as the robbery charges that had preceded it. Harry Pierpont was tried specifically for Sarber’s murder and executed for it.
