From the times article at least one of the women has physical evidence frozen, texts from Brands and documentation of therapy for rape. You'd assume there would also be a pretty large paper trail for the 16 year old too if he got taxis for her and that her family are also prepared to comment on the record.
Nadia, meanwhile, had told a close friend what had happened and she took her to the Rape Treatment Center (RTC) at UCLA Santa Monica Medical Center that same day. She has shared a full copy of her treatment records, which state that she provided her underwear and other samples as evidence, which were frozen. An officer from the Los Angeles Police Department was alerted by the centre, according to the notes, but she chose not to make a police report — saying to the centre she “didn’t think my words would mean anything up against his”. The notes also state that “she was worried that, if her assailant’s name is somehow released, then her name will be dragged through the dirt”. Nadia had therapy at the clinic for the following five months.
Bloody hell. We have to hear his side of the story but from what you're saying the programme revealed it sounds like he's going to find himself in one heck of a fight.
