The father and brother of Amber Canardo, both of whom would physically and sexually abuse her in the woods during her youth. When there was an opportunity for authorities to formally investigate the abuse, Amber's mother protected her husband and son by saying Amber lied. The two presumably continued their abuse afterwards. It is unknown what happened to them during the events of the episode.

The I-80 Killer
A serial killer targeting co-eds along Interstate 80 in Indiana. According to Prentiss's profile, he is an organized white male in his early thirties who is quite the charmer, able to smooth talk educated women who know there's a predator out there into his car. Eight of his eleven victims were reported missing on Friday mornings and were theorized by Prentiss to have been picked up at the Ranch House, a well-known nightclub in Gary that has a popular ladies' night on Thursday. Coincidentally, Interstate 80 was also the same route prolific serial killer Frank Breitkopf took while looking for his victims all across the country.

Sarah Danlin's rapists
A group of men who raped future serial killer Sarah Danlin on February 19, 1998, during Mardi Gras. Due to a disagreement between the two detectives investigating the case, Sarah was eventually persuaded by one of the detectives (who knew one of the assailants) in dropping the charges against the men. This would later lead to Sarah committing her murders. Interestingly, a flashback of the rape showed two suspects, although a police report indicated three offenders.
