On the night of June 21, 2025, 43-year-old Hector Garduno was fatally shot in the parking lot of Summa Sushi, 15218 Summit Ave., in the Falcon Ridge Town Center in Fontana. He and 40-year-old fitness influencer Gloria Zamora had been at the restaurant for about an hour when a man identified by police as Zamora’s estranged husband, 45-year-old Thomas Alberto Tamayo Lizarraga, confronted them and opened fire. Both Garduno and Zamora were killed in the ambush.

An off-duty San Bernardino County Sheriff’s deputy intervened and fatally shot the suspected gunman near the scene; authorities have not named the deputy. With the suspected shooter deceased at the scene, there were no arrests, and Fontana police said the investigation remained ongoing. Tributes after the attack identified Garduno as a father of four and noted his death as part of the June 21 gun violence in Fontana.
