Austin John Mueller, 19, of Sanford, Florida, was found with a gunshot wound to his stomach at a Decottes Avenue residence on April 20, 2018. Sanford Fire Department personnel arrived first; Mueller was taken to a nearby hospital and died of his injuries.

Police say the shooting followed an argument with 21-year-old Nicholas Kyle Keefer, who was at the scene. Keefer was arrested and charged with second-degree murder after investigators concluded he intentionally fired the weapon. Investigators reported Keefer gave multiple false statements, at first claiming Mueller had tossed the gun and it discharged accidentally. Keefer then attempted to hide the gun in a nightstand and told his girlfriend to apply pressure to Mueller’s wound. It was about 20 minutes before anyone in the house called 911.

The case centers on whether the shooting was deliberate and on Keefer’s conduct after the shooting. Did anyone who knew Austin or was at that house that night come forward with information about the argument or the delay in calling for help?
