Overview

• Phoenix police say a road-rage confrontation at 7th and Missouri on Saturday ended when a woman fired once from her SUV, fatally wounding 54-year-old Stephen Guardino.
• Witnesses reported the SUVs had been driving erratically and that Guardino approached the woman's vehicle and spat on her before the shot was fired.
• The woman was taken into custody and claims self-defense, with detectives seeking surveillance video and other evidence; no charges have been filed.
• A criminal defense attorney said the claim may hinge on proportionality and the “reasonable person” standard, describing the situation as a borderline case.
• In a separate case Sunday near 32nd Avenue and Bell Road, SAU officers shot a man who emerged from an apartment with a gun after hours of negotiation; he died at a hospital, no officers were hurt, and DPS’ Major Incident Division is investigating, marking the 31st officer-involved shooting in Maricopa County this year and the 64th statewide.
