On April 26, 2018, Bill Cosby was convicted of drugging and sexually assaulting Andrea Constand, whom he had met through her job at Temple University. As Nicole Weisensee Egan explains in her new book, “Chasing Cosby: The Downfall of America’s Dad” (Seal Press), Constand first went to the police in January 2005. Egan, then a Philadelphia Daily News reporter, aggressively pursued the story but, despite 13 other women coming forward with similar accounts, the DA closed the case a month later. In 2014, a video of comedian Hannibal Buress calling Cosby a rapist went viral, prompting more than 60 women to come forward saying he drugged and sexually assaulted them, or attempted to do one or the other. In 2015, the DA’s office reopened the case, charging Cosby with three counts of aggravated indecent assault.
