Leo Hemmer


Jailer Leo Hemmer was shot and killed as he brought food to the prisoners he was guarding.

As Jailer Hemmer opened the door to a holding area to deliver food, he was jumped by three prisoners, one of who pulled a revolver out of his pocket and shot and killed Jailer Hemmer. It is unknown how the revolver was smuggled into the jail. One of the suspects was arrested later that day.

Three weeks later deputies surrounded a house in Clinton, Illinois, where the other two suspects were found to be hiding. One shot and killed himself. The other surrendered.

Jailer Hemmer had been employed with the Dubuque County Sheriff’s Department for eight months, and was survived by his wife, two children, his mother, and several brothers and sisters.
