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.

Kern resurfaces with a new modus operandi–he now hits the victim, binds her with cuffs, and suffocates her with a plastic bag. He changed his MO because of his accident, which handicapped him. The women that he is now killing were the women that he planned to kill all those years ago–thus, his “unfinished business.”

After finding a picture of a teenage Riley in Sarah Jean’s cell, Gideon had Garcia do a trace on the child and discovered that he was still alive and had been adopted. Jacob Dawes went to his death knowing his son was still alive, as Hotch told him just before his execution. Although the team knew that Sarah Jean was innocent, she would not cooperate with the team as she felt he was better off not knowing who his real parents were and the reputation/legacy they left behind. She gave up her life to protect her son.
