What began as a warm summer bonfire in a Sioux Falls backyard ended in a mass shooting that killed 43-year-old Kellie Elizabeth Reaves and two other guests in the predawn hours of June 8, 2024. About a dozen people were attending the gathering when a man later identified as Justin Cody Rackley, 30, arrived after meeting someone from the group earlier that evening. Around 2:45 a.m., gunfire erupted; Kellie Reaves, Daniel Carl Kemnitz, 43, and Michael Andrew Thompson, 34, were found fatally shot and two others suffered non-life-threatening injuries.

Police arrested Rackley at the scene and recovered a handgun. He was charged with three counts of first-degree murder, pleaded not guilty at his initial court appearance, and had bond set at three million dollars. Authorities said the shooting did not appear to be a robbery or a crime of passion, and investigators had not announced a definitive motive. Kellie Reaves leaves behind a teenage daughter and a young son and was remembered by friends as a devoted mother and loving friend.

Does anyone who attended the bonfire or who knew Kellie have information that could help explain what happened that night?
