Back at This Week's Motel Room, Sam sighs, shrugs himself into his jacket, and darts off to...

...the crime lab, where Coroner Boy fills him in on the particulars of yet another extremity-free victim until Detective Charlene barges in to wonder why the FBI's chosen to involve itself in this specific case. Dapper Sam, clearly unprepared for the question, hems and haws and stammers and stutters and flails his arms around in the air for a good fifteen minutes until Coroner Boy offers him an easy out by stating, "I just figured it was the similarity to the other cold cases." "If it's the same killer," Coroner Boy goes on to suggest, "then he crossed state lines, which would bring you guys in." Dapper Sam readily agrees, but Detective Charlene obviously remains unsatisfied with this explanation, and she curtly orders them both to wrap things up, pronto, as her department has better things to do with its time. With that, Detective Charlene spins on her well-shod heel to stomp on out of there, and when Dapper Sam makes "Bitch crazy!" eyes at Coroner Boy, the latter sighs, "You get used to her."

And with all that out of the way, Dapper Sam inquires after those mysterious cold cases Coroner Boy just mentioned. Coroner Boy hands over the extensive files he's been maintaining, then notes something curious that all of the victims, current and past, had in common: Each had indulged in a one-night stand in the days leading up to his murder. Dun-dun-DUN!
