Members of the group “participated in their online child exploitation activities because they wanted to create an army of sadist followers.”

Federal prosecutors say four members of a neo-Nazi group ran a child exploitation ring that coerced minors into producing sadistic, abusive pornography.

In the case of the San Bernardino County children, a boy, identified in the indictment as co-conspirator R.M., conspired with a girl identified as Minor Victim 13 as well as a co-conspirator to produce pornography of herself and a prepubescent child, both county residents.

Four men face charges after investigators said they took part in an online neo-Nazi group that exploited children, according to the U.S. Department of Justice.
