The FBI says every single field office has open investigations related to a network of predators who coerce teenage victims into self-harm, child pornography and animal abuse. Those are just some of the crimes attributed to members of 764, a loose association of violent criminals who apparently enjoy tormenting others for status and amusement. There are related cases connected to the group in countries around the world and the FBI says there could be thousands of victims. The name of the group is attributed to the first three digits of the zipcode for Stephenville, Texas, the hometown of group founder Bradley Cadenhead, currently serving an 80-year sentence for child pornography.
