His sister discovered his body around 11 a.m.; he had been shot in the back of the head and no weapons were found at the scene.

Despite the multiagency investigation, no arrests or suspects have been publicly identified and the case remains unsolved. Investigators and the family have described gaps including the lack of a weapon at the scene and no named suspects, which have hindered progress.
