Ok, so I don't remember exact details. But it was an episode where it started off with a woman taking a shower and then it's revealed that the episode is about a rapist/sexual assault? Basically, the perp forced his victims to take showers after he finished with them so there would be no DNA. And that he got his victims from like a marketing list. (where people sign up for more information on a product/company). Also the perp wore a mask when he assaulted victims and the detectives had to track down this mask??? pls help.
