Armando Salazar, 40, was shot to death at his west Phoenix home after answering a persistent knock at the front door on a November night. He opened the solid main door while the outer security door remained locked; someone then fired through the metal screen, and he collapsed. His wife was in the house and was not physically harmed.

Emergency responders found Salazar with no signs of life at the residence in the 4000 block of North 64th Drive, near Indian School Road and 67th Avenue. Phoenix police responded and the Violent Crimes Bureau and Silent Witness became involved; investigators reported no clear motive and no immediate suspects. The shooter or shooters fled, and despite appeals for information and a potential reward, the case remained unsolved.

Were there any neighbors or visitors in that area that November who remember unusual activity or a vehicle near the house?
