On 8 September 2015, 22-year-old Iranian American Shayan Mazroei was stabbed to death by white supremacist Craig Tanber. Mazroei, who resided in Laguna Niguel, was a successful businessman operating his own car dealership in Santa Ana. On the night of 8 September 2015, Mazroei began discussing his mother visiting Iran to his girlfriend in a restaurant until Elizabeth Anne Thornburg spat on Mazroei shouting racial slurs. Tanber, who would later be sentenced to life in prison, then proceeded to stab Mazroei resulting in his death.
