Casey Shawn Edward Shaffer, 30, was found shot to death in a Sioux Falls apartment at 808 West Bailey Street in the early hours of September 6, 2024. Responding officers discovered Shaffer on the living room floor with multiple gunshot wounds from a small-caliber handgun after a woman called to have an individual removed from her residence.

The woman had accused Shaffer of sexually assaulting her six-year-old son; Shaffer denied the allegation in a text exchange with the mother. That accusation led to a confrontation involving 30-year-old Dylan Tyler Farmer, an associate of both Shaffer and the woman. Farmer reportedly attempted to turn himself in at the Minnehaha County Jail earlier that day, confessing to the shooting, but authorities initially dismissed his statement until Shaffer’s body was located. Farmer’s credit card was found at the scene, and he was arrested and charged with first- and second-degree murder. Law enforcement says the parties knew each other and the killing was not random; Farmer told detectives he shot Shaffer in the face because he believed Shaffer had inappropriately touched a child.

Anyone with information about Shaffer, the events at 808 West Bailey Street, or who saw the people involved that night is asked to come forward.
