Mere minutes after the execution of an infamous serial killer, a copycat begins to commit crimes in the same town with the same MO. The BAU is forced to act fast â€" the UnSub isnâ€™t wasting any time, and bodies are being found every six hours. As the team meets with the executed killerâ€™s ex wife in a search for suspects, the UnSub begins to escalate his plan. While the first two women murdered are found with cut hair, the third is discovered with a shaved head. The fourth body is found after having been scalped entirely.
