Okay, more convince than ever that the wig wearing T.A. is the rapist, and that he orchestrated the Mercer frame up (notice how his inside man at the Neptune Grand was right there when they opened the car trunk). He probably has alopecia or something and that's why he shaves the girls heads. He also woud know what evidence woould be collected in the rape kit, so he either cleans up thoroughly or he's just careful, hence no dna evidence. I know V won't let him get away with it.
