A 19-year-old Illinois man who identified as a neo-Nazi was arrested after a coworker tipped off authorities to his plans for a mass shooting at a Hindu temple in Aurora.

Alexandros Paporakis of Palatine faces charges of making a terrorist threat and unlawful possession of a weapon. Prosecutors said he sent an eight-page manifesto titled "Why I fought: A.K.A. (Aurora Shooter’s Manifesto)" to a Taco Bell colleague on Sunday, October 11, describing his intent to kill as many non-white people as possible, with particular focus on Indian worshippers.

The document expressed hatred toward Jewish people, African Americans, Indians and other "non-white" individuals, whom Paporakis called "subhumans," according to court records. He described himself as "a sociopathic white supremacist Neo Nazi filled with hatred, fantasizing about mass murder nearly every day."

Paporakis drove to the temple parking lot that afternoon in a red Honda RDX. Surveillance footage showed his vehicle entering around 12:25 p.m. and leaving about 13 minutes later. Prosecutors said he attempted to fire an AR-style rifle at a man but the weapon jammed. He later texted the coworker that the man was "certainly saved by his God today."

Police recovered the rifle, multiple loaded magazines, approximately 300 rounds of ammunition, a gas can, tactical vest with body armor, and Nazi-related items from his home. He had been planning the attack for about two years and targeting the temple for two months, records show.

Paporakis appeared in court Wednesday and was ordered detained pending further proceedings. His next court date is October 30. The FBI assisted local departments in the investigation.

The temple implemented additional security measures following the incident. Authorities credited the coworker's quick report with preventing potential tragedy.
