An alleged former roommate of Nick Reiner is speaking out and claiming his disturbing behavior traced all the way back to when he was just a teen. While speaking with DailyMail.com recently, a man named Danny Svilar claimed to have stayed in a high-end rehab facility with Nick when they were both just 15. And when he heard the news of Rob and Michele Reiner's deaths? Well, he had one chilling thought: "As soon as I saw that Rob Reiner and his wife Michele were murdered, I knew exactly who it was." Whoa.
