New Facts: Court records reveal prior red-flag gun seizure

In January 2025, a welfare check at 18-year-old Caleb Vazquez’s home led police to flag him for idolizing Nazis and mass shooters. On Jan. 29, 2025 they obtained a court order under a 2014 California law to remove 26 guns from his father’s collection.

His father initially refused to let officers in to inspect how the weapons were stored. Days earlier the family had moved the guns out of the house to a storage unit and locked away sharp knives. Vazquez had previously been held for involuntary psychiatric treatment.

Vazquez met 17-year-old Cain Clark online. Weapons were reported missing from Clark’s home on Monday, prompting an hourslong search for the pair before the shooting. The source of the guns used in the attack has not been identified publicly.
