Sam Little, the FBI’s most prolific serial killer roamed free for five decades - how? Killing women at will, he was eventually brought to justice by the women who were out to get him. This opportunistic killer stayed below law enforcement’s radar because of the victims he chose: Women from the fringe — drug users and sex workers were paid little attention to by society. But in 2012 he came to the attention of Detective Mitzi Roberts and everything changed. The Los Angeles Police Department cold case investigator relentlessly hunted Little across the country to capture and convict him with the help of a group of equally fierce women that included a prosecutor, a writer and several women who survived brutal attacks from Little.
