TOP STORY
Newly obtained court documents reviewed by Team 10 reveal that one of the gunmen in the May 18 deadly shooting at the Islamic Center of San Diego displayed troubling warning signs more than a year before the attack.
According to the records, suspect Caleb Vazquez had dressed up as notorious killers linked to mass shootings. At age 17, he admitted to dressing as Luigi Mangione, the man accused of killing UnitedHealthCare CEO Brian Thompson in 2024.
The documents also stated that Vazquez attended class at High Tech High in Chula Vista dressed as the fictional TV serial killer Dexter.
In January 2025, Chula Vista police conducted a welfare check after the then-17-year-old told a friend not to attend school the next day. That incident and other concerns led to Vazquez being placed under a 72-hour mental health hold.
Retired FBI agent Jennifer Coffindaffer said these behaviors reflect a broader, nationwide trend in teenage mass violence.
“They become oriented surrounding their race. They become very hateful toward anybody that isn't their race or religious group, and they find and target individuals to hate. And that's what you're seeing here,” Coffindaffer said.
Police obtained a Gun Violence Restraining Order against Vazquez in 2025, but a judge dismissed it two weeks later.
