On the night of June 21, 2025, 43-year-old Hector Garduno, a male from Fontana, was fatally shot alongside 40-year-old fitness influencer Gloria Zamora as they left a sushi restaurant in the Falcon Ridge Town Center on Summit Avenue. Police said the pair had been at the restaurant for about an hour before the ambush in the parking lot; records place the scene at Summa Sushi, 15218 Summit Ave., in Fontana.
Investigators identified the gunman as Zamora’s estranged husband, 45-year-old Thomas Alberto Tamayo Lizarraga, who confronted the couple outside and opened fire, killing both. Accounts describe the attack as an ambush that followed Zamora’s recent public discussion of her separation; officers emphasized the couple’s ongoing divorce.
As the chaos unfolded, an off-duty San Bernardino County Sheriff’s deputy intervened and fatally shot the suspected gunman during a confrontation near the scene. Authorities have not publicly named the deputy. With the suspected shooter deceased at the scene, there were no arrests in the case, though Fontana police said their investigation into the double homicide continued.
In the days that followed, tributes identified 43-year-old male victim Hector Garduno as a father of four and memorial pages marked his death as a loss to gun violence on June 21 in Fontana. Public reports and crime databases corroborated the victims’ identities, ages, and the date and location of the attack.
