Jackson Cally and his group are responsible for killing the five college students, the Minton family (three young daughters, the husband and wife), and a police officer. By killing the five college students, they made it look like it was part of a Native American ritual. Upon further investigation into the crime scene, the team realizes that it could not have been done by just one tribe. Cally did 22 months in jail for auto theft and “found” religion. Upon his release from jail, he went from university to university where he studied Native American culture, and it was at the last university that he met and “brainwashed” Ingrid Greisen. He created his own “tribe” on the Indian Reservation. Cally sends other members of his “tribe” to attack the reservation and Hotch and Blackwolf stopped them.
