San Antonio-Based ‘764’ Extremist Group Leader Pleads Guilty to RICO, Child Sexual Exploitation Charges

"Chavez led a group of online predators whose ultimate purpose is to destroy our society. They tried to achieve that heinous goal by desensitizing innocent children to violence—coercing them to perform gruesome and harmful acts against themselves and animals—with the hope of encouraging further violence and spreading chaos," said Sue J. Bai, Principal Deputy Assistant Attorney General for National Security. "The National Security Division will continue to relentlessly investigate and prosecute predators who seek to terrorize our society by targeting our most vulnerable."

“764 members, like the defendant, use the Internet to prey on vulnerable minors, coercing them to mutilate themselves, produce child exploitation images of themselves, and attempt suicide," said U.S. Attorney Justin R. Simmons for the Western District of Texas. "My office will do everything legally possible to prosecute and imprison members of this group for as long as the law allows."

According to court documents, Alexis Aldair Chavez, also known as Zack and Zack8884, 19, was an administrator and online leader of the ‘8884’ network, which is a network related to 764. Both 8884 and 764 are NVEs who engage in criminal conduct within the United States and engage with other extremists abroad. These NVEs share accelerationist goals that include social unrest and the downfall of the current world order, including the U.S. Government. Members of 8884 work in concert with one another towards a common purpose of destroying civilized society through the corruption and exploitation of vulnerable populations, including minors. NVEs engage in criminal conduct within the United States and abroad, in furtherance of political, social, or religious goals that derive primarily from a hatred of society at large and a desire to bring about its collapse by sowing indiscriminate chaos, destruction, and social instability. NVEs demand, coerce, and extort victims to engage in variety of violent conduct, including self-mutilation, online and in-person sexual acts, harm to animals, sexual exploitation of siblings and others, acts of violence, threats of violence, suicide, and murder.

In or about October 2023, Chavez and a co-conspirator attempted to have a minor female kill herself in a video chat by overdosing on pills. The two conspirators recorded the attempted suicide to obtain “content” that would allow them to maintain and increase their status in the 8884 enterprise. Approximately two months later, Chavez and the minor female victim worked together to coerce a female located overseas to get naked on camera, cut herself, and engage in sexual acts. They also extorted another female by forcing the victim to cut the name “Zack” into herself.

On or about Dec. 29, 2023, Chavez and a co-conspirator coerced another minor female to cut her tongue as well as torture and kill a cat on a live video call. That same month, Chavez and another co-conspirator worked together to groom and extort several other minor females. In one instance, the two conspirators coerced a female victim to light her arm on fire and have the fire burn through her skin and deeper into her body, while on a recorded video chat within the ‘8884’ channel. They groomed another minor female victim, forcing her to drink her own urine and attempt to overdose on unknown pills.

On or about Jan. 23, 2024, Chavez and a co-conspirator threatened and coerced a minor female victim to engage in sexually obscene activities and other egregious acts.

Chavez pleaded guilty to one count of racketeering, one count of distribution of child pornography, and one count of possession of child pornography. He faces up to 20 years in prison for each count, with a minimum of five years in prison for the distribution charge. A federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.

The FBI San Antonio Field Office is investigating the case with assistance from FBI Washington Field Office, Homeland Security Investigations, and the San Antonio Police Department.

Assistant U.S. Attorneys Mark Roomberg and Bill Harris for the Western District of Texas, and Trial Attorneys Justin Sher and James Donnelly of the National Security Division’s Counterterrorism Section are prosecuting the case.

The Justice Department remains vigilant against the threat of Nihilistic Violent Extremist (NVE) networks, like 764, that operate within the United States and around the globe. NVEs often target vulnerable individuals, including minors, using social media platforms to share CSAM and gore material, and groom victims toward committing acts of violence. Victims are often extorted, coerced, compelled, and blackmailed into complying with NVE demands, including self-mutilation, online and in-person sexual acts, harm to animals, sexual exploitation of siblings and others, acts of violence, threats of violence, suicide, and murder.
