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.

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.
