Season 8: Episode 6 - The Apprenticeship

The Apprenticeship: An UnSub in Miami has escalated from animals to people â€" a prostitute’s body has turned up with a bag over her head, the same MO that was used to kill several local dogs. The BAU hopes to find the UnSub before it turns into a spree, but things get out of control fast. Not only do the police find several more dead hookers in a short time span, but these killings show far more sophistication. Our team comes to the conclusion that an older, established UnSub must be training his young protégé how to kill â€" and neither is showing any sign of slowing down.
