Jennifer Thompson has told her harrowing tale many times. In 1984, a man broke into her apartment and sexually assaulted her at knifepoint. She picked Ronald Cotton out of a police lineup, and he was sent to prison. But a decade later he was proven innocent and released. The two met and eventually co-authored a book, “Picking Cotton.” They toured the country, advocating for laws that might prevent such tragedies. The real perpetrator, Bobby Poole, was identified through DNA, and died in prison in 1998.
