Kerri Rawson, the daughter of serial killer Dennis Rader (also known as BTK), shared 200 sketches her father drew with law enforcement to help identify potential other victims. At least nine open cases have been identified across three states where Rader is now considered a suspect based on the sketches. Kerri Rawson works with local agencies in Oklahoma and Missouri on two prominent cases from those states. Rawson feels well-equipped to help analyze the sketches and crime scenes due to her expertise in her father from knowing him personally. She hopes to solve open cases or rule Rader out as a suspect to give victims' families long-awaited answers.
