SAN ANTONIO - A 19-year-old administrator of an online nihilistic violent extremist network linked to the 764 movement was sentenced to 40 years in federal prison for racketeering and multiple counts of child sexual exploitation, the Department of Justice announced.
Alexis Aldair Chavez, who operated under the aliases “Zack” and “Zack8884,” served as an online leader of the 8884 network, a group related to 764 that prosecutors described as sharing accelerationist goals including the downfall of the U.S. government and the destruction of civilized society through the exploitation of minors. In addition to the 40-year sentence, Chavez was ordered to pay $10,000 in restitution and will face lifetime supervised release.
“Chavez’s crimes reveal the ruthless exploitation and manipulation at the core of NVE groups,” said Assistant Attorney General for National Security John A. Eisenberg. “These organizations target children as part of their broader mission to spread terror. These groups ultimately seek nothing less than the destruction of our society. NSD will use every resource at its disposal to identify and prosecute 764-linked criminality and to protect the most innocent among us from these predators.”
Court documents detail a pattern of sadistic coercion spanning months. In October 2023, Chavez and a co-conspirator attempted to have a minor female kill herself by overdosing on pills during a video chat, recording the attempted suicide to gain status within 8884. Two months later, Chavez and the same victim coerced a female overseas to strip naked, cut herself, and engage in sexual acts on camera. They extorted another female into cutting the name “Zack” into her own body. Around Dec. 29, 2023, Chavez and a co-conspirator coerced a minor female to cut her tongue and torture and kill a cat on a live video call. In another instance, conspirators forced a victim to light her arm on fire while recording the act within the 8884 channel, and groomed another minor into drinking her own urine and attempting to overdose.
“What Alexis Chavez and other members of these Nihilistic Violent Extremist groups have done to the vulnerable children they target is among the most disturbing conduct this office has prosecuted,” said U.S. Attorney Justin R. Simmons for the Western District of Texas. “Parents need to know what their children are doing online and must stay engaged, ask difficult questions, and not fall into the trap of believing their child is ‘just playing games’ or ‘just talking with their friends.’ There is darkness present within many people in this world that want nothing more than to see the United States and western civilization fail.”
“Nothing is more abhorrent than those who prey on children and other vulnerable members of our society and this defendant will pay a steep price for doing just that,” said Acting Assistant Director Coult Markovsky of the FBI’s Counterterrorism Division. “The FBI has made it a high priority to identity and arrest Nihilistic Violent Extremists who coerce juveniles into horrific acts of self-harm.”
Special Agent in Charge Daniel Faith of the FBI San Antonio Field Office said the case demonstrates the bureau’s resolve to dismantle networks like 764 that use social media, messaging apps, gaming platforms, and chat rooms to groom vulnerable children. “Staying engaged in your child’s online life, maintaining open communication, recognizing the warning signs, and reporting suspicious online activity to law enforcement are critical to stopping these offenders,” Faith said.
Chavez was arrested on Oct. 24, 2024, and pleaded guilty on Dec. 19, 2025, to one count of racketeering, one count of distribution of child pornography, and one count of possession of child pornography. The case was investigated by the FBI San Antonio Field Office with assistance from the FBI Washington Field Office and prosecuted by Assistant U.S. Attorneys Mark Roomberg and Bill Harris alongside Trial Attorneys Justin Sher and James Donnelly of the National Security Division’s Counterterrorism Section. The case was brought under Project Safe Childhood, the DOJ initiative launched in May 2006 to combat child sexual exploitation.
