Turning pro as a 6'1" orthodox super lightweight (140 lbs), Valdovinos compiled an impressive record of  8-2-1 and 6Ko's, competing until around 2021. Labeled a "California boxing prospect," he trained diligently at Hanford PAL, earning admiration from family and peers for his forgiving and compassionate traits.

On May 3, 2026, around 4 a.m., tragedy struck at a home in the 0 block of University Avenue near Stanford Avenue—Hanford's third homicide that year. Vincent Diaz, 33, a convicted felon and ex-husband of Valdovinos' girlfriend, parked 100 yards away, forced entry with a high-capacity illegal firearm, and shot Valdovinos multiple times in a bedroom. Diaz then fatally shot himself as police arrived after a 911 call reporting an argument and gunshots; the event lasted under 10 minutes, with no known prior conflict between the men. Diaz and his ex-wife had separated since August 2025; she sought a restraining order in March over their child.

Hanford united in grief, holding a candlelight vigil on May 6 at 8 p.m. at Civic Center Park (400 N. Douty St.), organized by brother Ruben Valdovinos. Attendees displayed boxing gloves, photos, and tributes, with his father calling for reflection on Adrian's legacy and aunt Christine Aguilar lamenting a "big loss." Local news and social media captured the outpouring of prayers and support for the "tremendous amount of hurt" felt citywide.

The investigation continues, with Hanford PD seeking tips on the firearm at (559) 585-2540; Valdovinos' story underscores both rising promise and senseless violence.
