A former NBC employee has come forward to say that years of "covering up" for Bill Cosby eventually made him quit his job. Frank Scotti tells the New York Daily News that he was essentially Cosby's yes-man - standing guard outside the comedian's dressing room while he brought young models in, paying off women in exchange for their silence, and even securing a second apartment for Cosby's exploits. Scotti says he's speaking out now because he "felt sorry for the women" who are coming forward to accuse Cosby of sexual assault. A 47-year-old Pittsburgh resident says she was assaulted by Cosby when she was a 15-year-old model and aspiring actress who appeared in some of Cosby's videos. Renita Chaney Hill tells the CBS Pittsburgh affiliate that, over the course of four years, she had several encounters with Cosby that started with him giving her a drink and ended with her waking up after being passed out. According to Showbiz411, Law & Order: SVU actress Michelle Hurd has also accused Cosby of sexual abuse. The website reports that Hurd, who has also starred on 90210 and Gossip Girl, wrote a lengthy Facebook post about her experience with Cosby. Scotti, who worked as a facilities manager at the studio in Brooklyn where The Cosby Show was taped, tells the Daily News he paid eight women monthly installments of up to $2,000 between 1989 and 1990, when The Cosby Show was at its peak.
