A surprising possible link between the Idaho murder suspect and the infamous BTK serial killer is coming to light. Bryan Kohberger has a master's degree in criminology from DeSales University in Pennsylvania. He studied under a well-known forensic psychologist and serial killer expert, Dr. Katherine Ramsland. Dr. Ramsland collaborated on a book with the notorious BTK murderer, Dennis Rader. Rader’s daughter says she wouldn't be surprised if Kohberger contacted her father.
