Police made a wellness check to the Vazquez home in January 2025 and sometime thereafter Caleb Vazquez was placed on a psychiatric hold, according to court documents filed in California Superior Court in San Diego County. This resulted in the Chula Vista Police Department serving Vazquez with the gun violence restraining order, which prohibits someone from buying or owning firearms, ammunition and magazines.

At that time, officers asked his father, Marco Vazquez, if he had any guns at the house, according to a declaration filed with the court by Marco Vazquez. He confirmed to officers that there were firearms in the house but explained that he kept them locked in a safe that was stored in a locked closet, which he said no one else had access to.
