Merritt Wever, who recently picked up an Emmy for her main role on Godless, plays Karen Duvall, a character based on Detective Stacy Galbraith, who reached out to Hendershot after seeing similarities between their cases. While less experienced than Hendershot at the time, Galbraith had still worked on dozens of rape cases before. She and Hendershot would team up with other police departments to track down the suspect.
