Dr. Stone studies killers that are considered highly intelligent compared to others. Edmund Kemper had his first taste of murder at a young age by killing his grandparents, and was soon sent to a Mental Institute but was released early due to good behavior, while serving there however he was pass several IQ-related tests and became quite good friends with his psychologist, but a decade after his release, he went back to killing and murdered seven women and soon his own mother before turning himself in, and during this period, he befriended police before going on his killing spree so he wouldn't be a reasonable suspect. H.H. Holmes was not just a serial killer but also a con artist, and his killing spree made him to be the first American serial killer. Ted Kaczynski was a highly intelligent man with a high IQ but however suffers severe delusional issues which makes him to believe that the current technology is harmful to mankind so he would decide to send letter bombs to Universities that worked on the development of Computers and ends-up killing three people, injuring dozen of more, taking the name the "Unabomber", and while committing these acts of terrorism, lives in a cabin out in the country, leaving fake addresses, and eventually Kaczynski would be capture once after a manifesto he made for the press went viral in which his brother who read a different topic-letter he made, recognizes the way it wrote.
