On Tuesday, May 20, 2025, Michael Bradford, 46, was found with a gunshot wound to his upper torso in the carport area of a residence near the 1800 block of North Miller Road in Scottsdale, Arizona. Emergency responders extracted Bradford from the scene and he was taken to a local hospital, where he was pronounced dead despite life-saving efforts.

Police identified 48-year-old Sean Quinn as the suspect. Quinn retreated into the home after the shooting; negotiators made contact but he refused to surrender. A police canine was deployed, bit Quinn during a brief struggle, and he was taken into custody. After medical clearance Quinn was booked into the Maricopa County Jail on one count of second-degree murder. Reports say Bradford and Quinn had been friends for many years and there were no known prior issues between them. The motive has not been released.

Did anyone in the Scottsdale area know Bradford or Quinn, or have information about their relationship leading up to May 20?
