According to NBC News, the second suspect has been ruled out: “Authorities tell NBC News they have interviewed the ‘person of interest’ in the Arizona shooting [and] are now satisfied he was merely at the Safeway store and not connected to the shooting or the suspect in any way.”

The New York Times notes: “Investigators said that the second man was a taxi driver who drove the suspected gunman to the scene. Upon arriving there, the passenger said he did not have change and he and the taxi driver went into the supermarket for change and the two then walked out together and separated.”
