A Tennessee man identified by federal authorities as a prominent member of the violent online network known as “764” has received a 77-year federal prison sentence for sexually exploiting children and helping distribute videos depicting severe animal abuse.
Kyle William Spitze, 27, of Friendsville was sentenced Wednesday following a hearing that extended over portions of two days. The Justice Department described the punishment as the longest federal sentence yet imposed on someone classified as a nihilistic violent extremist.
Spitze pleaded guilty to two counts of producing child sexual abuse material, one count of aiding the distribution of animal-crushing videos and one count of possessing and accessing child exploitation material with the intent to view it.
In addition to his prison term, Spitze received lifetime supervised release. If ever released, he will be required to register as a sex offender and comply with special conditions governing convicted sexual offenders.
Federal officials identified Spitze as an original member of 764 and an administrator of an affiliated network called HarmNation. He operated online under names including “Crimhn,” “Criminal” and “Criminaloli.”
According to the Justice Department, these networks deliberately target emotionally vulnerable children through social media and encrypted communications. Members use manipulation, threats and blackmail to pressure victims into producing sexually explicit material, injuring themselves, harming animals or carrying out other violent acts.
Prosecutors said the abuse was connected to a nihilistic ideology centered on creating chaos and accelerating the collapse of society.
The FBI began investigating HarmNation in December 2023 after receiving information that members were circulating child sexual abuse material. Investigators determined that Spitze operated an online channel containing images and videos of underage girls who had been coerced into mutilating themselves.
A search of Spitze’s phone in February 2024 uncovered additional exploitation material involving minors, according to federal authorities. One victim later told investigators that Spitze threatened her into creating images for him.
Federal investigators have connected Spitze to approximately 30 victims, although only some have been fully identified. Prosecutors said Spitze himself claimed online to have groomed thousands of people, but that assertion has not been independently substantiated.
Court filings said two known victims later died by suicide. Prosecutors alleged that Spitze managed to contact them after his incarceration, reinforcing their belief that they could not escape his harassment.
Authorities also accused Spitze of continuing disturbing behavior while confined at the Blount County Jail.
A supplemental sentencing filing alleged that he established a jailhouse group known as “Colts Harmnation,” which participants reportedly described as a devil-worship organization. Correctional officers learned that Spitze and two other inmates had engaged in sexual activity in an area of the facility called the “cave.”
One inmate reportedly carved the group’s symbol into his chest, while the same marking was discovered on a wall. Officers also found concealed razor blades among inmates in Spitze’s housing area, including one reportedly hidden inside a personal Bible.
Spitze’s attorney disputed the government’s portrayal of the jail incidents and accused prosecutors of exaggerating the evidence. The court nevertheless imposed the full 924-month sentence requested by the government.
Assistant Attorney General John Eisenberg said the sentence demonstrated that society would not tolerate organized efforts to exploit children in pursuit of extremist goals.
The case forms part of a broader federal campaign against 764 and related networks. The Justice Department has brought charges against multiple alleged members across the United States and abroad, describing the organization as a global child-exploitation enterprise disguised as an extremist movement.
For Spitze’s identified victims and their families, the 77-year sentence ensures that he is likely to spend the remainder of his life in federal custody.
