And here we have Rianne Olivier's class photo. Olivier, you recall, was Reggie Ledoux's girlfriend, until she disappeared and her body was found washed up in the bayou.
Investigators concluded she drowned, but after reviewing thousands of photos of dead bodies, hers caught Cohle's eye, because of the tell-tale spiral on the shoulder and the same mix of meth and LSD that was found in Dora Lange's body.
Olivier's grandfather let the detectives have her yearbook—she attended one of Reverend Tuttle's schools. Cohle has the photo up in his apartment.
As we know he's the same person as the one seen in the yearbook photo?
There's speculation that the "Marshland Medea" from episode 6 also went to Light of the Way school with Rianne Olivier.
Others suspect that the big guy in the far right corner is our landscaper guy from outside the school with the "Devil's Nests," a.k.a. The Green Eared Spaghetti Monster.
