Caleb Vazquez, 18, allegedly alarmed classmates and staff at High Tech High in Chula Vista after dressing up asnotorious murderersresponsible for some of the world’s deadliest mass killings, according to court documents.
A Chula Vista police detective detailed the incidents in a request for a gun violence restraining order filed last January.
The teen also reportedly came to class in 2024 dressed as Dexter, the fictional TV serial killer who secretly lives a double life as a blood splatter expert.
“He also admitted to dressing up similarly to the recent health care CEO shooter,” Det. Nicholas How wrote in the court filing, referring to Luigi Mangione, who is accused of killing UnitedHealthcare CEO Brian Thompson.
Court documents show Vazquez had become obsessed with mass murderers, including Patrick Crusius, who slaughtered 23 people in a 2019 Walmart massacre in El Paso, and Norwegian terrorist Anders Behring Breivik, who killed 77 people in twin gun and bomb attacks in 2011.
Vazquez and Cain Clark, 17, are accused of shooting three people at the Islamic Center of San Diego last Monday before dying in an apparent murder-suicide.
The teen first caught law enforcement’s attention after two friends raised concerns with the school’s assistant principal, according to the outlet.
Police later conducted a welfare check in January 2025 after Vazquez, who was 17 at the time, allegedly warned a friend not to come to school the next day.
