Calvin Shaw

Calvin Shaw is a recurring character who appeared in Season Twelve of Criminal Minds.

Background
Shaw was a highly respected agent who worked for the FBI's office in Detroit, Michigan. He and his coworkers were assigned to dismantle a drug trafficking operation in the area, and they used an informant to help them infiltrate the organization. However, the informant started blackmailing the team, threatening to blow their covers if they didn't increase her paychecks. Believing an arrest would still endanger the lives of his teammates, Shaw chose to kill the informant to silence her, and pin the murder on a rival gang. However, at some point, he was identified, stripped of his badge, and imprisoned. In prison, Shaw survived his first few months by reading books from the prison library and isolating himself from most inmates. He somehow developed a reputation with the inmate population, considering their willingness to follow his orders.
