Sergeant Koeller was shot and killed after surprising a group of burglars at a local business. While he was detaining two of the suspects a third suspect came up from behind and started to struggle with Sergeant Koeller. During the struggle the suspect shot him in the neck, before all three fled the scene.
A fingerprint lifted from the scene produced a suspect in Ohio three years later but he was not convicted. The shooter was arrested in Illinois, confessed to the murder, and sentenced to two life sentences.
