A Cinco de Mayo gathering at El Camaron Gigante in Glendale, Arizona, on the evening of May 4, 2025, ended in a deadly shooting that killed 17-year-old Damien Anthony Sproule. The event — a concert and car show that drew about 200 to 300 people — turned violent after a dispute inside the restaurant led to several people being escorted into the parking lot, where gunfire erupted at about 7:45 p.m.

Damien, described as a loving new father, was attending with his older brother Christopher Juaquin Sproule. Both brothers were fatally wounded; a third person, 21-year-old Milo Christopher Suniga, was also killed. Five other people suffered gunshot wounds, some serious. Glendale police characterize the incident as isolated and believe those involved knew one another; the department is seeking multiple suspects and has released images of people who might have information while asking the public for photos or video from the event.

A candlelight vigil was held at Murphy Park in historic downtown Glendale as family and friends mourned. If anyone attended the El Camaron Gigante event or has video or photos from that evening, please share what might help identify those responsible for Damien’s death.
