Criminal Minds (2005)

S8E1 The Silencer

During a prisoner transfer in Texas, an inmate makes a daring escape, leaving a trail of victims marked by his chilling signature: sewing their mouths shut. This distinct method is reminiscent of the infamous UnSub known as "The Silencer." As the BAU delves into the identity and transformation of the escaped convict, they also take the time to welcome and familiarize themselves with the latest addition to their team.
