"During the period covering fiscal years 2003 through 2006, the FBI initiated 1,658 investigations and made 537 arrests in matters involving Indian child sexual abuse. During the same period, the FBI initiated 134 investigations and made 39 arrests in matters involving Indian child physical abuse. This represents approximately 30% of all FBI investigations in Indian Country during that period. Crimes against Indian children have been, and will remain, a top priority for the FBI."
Theory time: Trump and his DOJ have taken great interest in these missing persons in the past year. I suspect the deep state is operating human trafficking rings on Indian reservations. They could easily fly under the radar on reservations through a combination of corrupt tribal officials turning a blind eye through bribery/blackmail and the difficulty state and federal law enforcement agencies have accessing and investigating on reservation land due to U.S. law.
