On the morning of June 30, 2025, a violent crime spree in Tucson ended with the death of 69-year-old Ricky Miller. Winstel Avenue while Miller was inside his Toyota Tundra. Witnesses heard a verbal dispute and then a single gunshot; Miller was transported to a hospital and died of his injuries. Witnesses also reported Aguirre pointing a firearm at two bystanders during the encounter.

The suspect allegedly continued the spree by forcing his way into a nearby home and holding occupants at gunpoint; some escaped while one person reportedly remained inside with him. A manhunt involving SWAT, K-9 and air units ended just before 9:20 a.m. when Aguirre was found hiding in a shed in the 2100 block of S. Richey Boulevard and taken into custody after receiving a K-9 bite. He faces state charges including first-degree murder and multiple counts of aggravated assault, and federal charges connected to the attempted carjacking and firearms possession.

Anyone who witnessed the confrontation or the events that morning in the 2100 blocks of S. Winstel or S. Richey Boulevard is asked to come forward with information.
