Two teenagers, Cain Clark (17) and Caleb Vazquez (18), carried out a deadly attack on the Islamic Center of San Diego, killing security guard Amin Abdullah and two other men before dying by suicide. The assailants were heavily inspired by the 2019 Christchurch mosque shooter, Brenton Tarrant, referring to themselves as 'Sons of Tarrant' and emulating his methods.
Manifesto and Ideology
The attackers left behind a 74-page manifesto, similar to Tarrant's, which contained far-right ideologies, including the 'white replacement' theory, and expressed hatred towards various groups. Extremism researchers highlight a growing trend of violent extremists online emulating past high-casualty attacks and using manifestos to spread their ideologies, a phenomenon they describe as 'gamifying' violence.
Contagion of Mass Violence
The incident underscores the contagion of mass violence and the rising threats against religious communities. It contrasts with the security guard's dedication to protecting his community from increasing anti-Muslim sentiment. The attack is a stark reminder of the influence of online extremism and the need for vigilance.
