Debbie Barnette, 65, was shot during a deadly episode tied to an escalating dispute with a neighbor in midtown Tucson on the evening of March 14, 2019. Multiple homes in her neighborhood were set on fire with incendiary devices; investigators later concluded three neighboring houses had effectively been fire bombed. Barnette was found critically wounded near Roger Road and Campbell Avenue in the area of East Duke Street and taken to Banner–University Medical Center, where she died after several days in the hospital.

Officers located Barnette and her neighbor, 54-year-old Donald W. Shoemaker, who was suffering from an apparent self-inflicted gunshot wound. Police later determined Shoemaker had ignited or thrown the incendiary devices, shot Barnette, and then turned the gun on himself. Shoemaker remained on life support and died in the hospital on March 24, 2019. No formal arrest was made because the identified suspect died, and case-tracking records describe the matter as solved with the primary suspect deceased.

Did anyone in the area witness activity near Roger Road and Campbell Avenue that night or have information about the dispute between neighbors?
