Criminal Minds Wiki

Marcus Lee Graham is a now incarcerated serial-turned-proxy killer who appears in the Criminal Minds: Suspect Behavior episode "Lonely Heart".


Graham's background is not specified, although it is possible that he was a sadistic and manipulative person his entire life. At some point in his life, he began killing younger, teenage girls, eventually murdering three. Sometime after killing his third victim, he approached a girl named Jill and began hanging out with her. At first, Jill enjoyed the relationship, but eventually noticed his sadistic personality when he tried to get her to bring a friend so he could torture her and tried to call off the affair, only to be stabbed by him. Surviving, Jill was sheltered by her mother. Meanwhile, he was arrested when a mailman saw blood on his driveway and the police found the bodies of his three victims buried behind his cabin. Sometime prior to Lonely Heart, he met Rachel Lancroft at an online dating website and manipulated her into killing single businessmen as a means of satisfying his psychopathic tendencies. When the Red Cell team interrogated him after discovering how similar Rachel's crimes were to his, he brought in Rachel as his lawyer. Later, the Red Cell team discerned Rachel as the serial killer and Simms and LaSalle managed to track her down to Jill's home, where she was about to kill her. Rachel committed suicide by cop, and Graham was uninformed of her death.

Modus Operandi[]

Graham would approach his victims and presumably use a ruse, and when they fell for it, he would stab them in places where they would bleed out very slowly, making their deaths long and very painful. He would then sit by their sides and watch them die. While the first three victims were buried behind Marcus' cabin, Jill, who survived by pretending to be dead, was left at the scene; it is possible that her surviving is what made him dispose of his victims' bodies the former way.

Real-Life Comparisons[]

Graham appears to be inspired by Ted Bundy - Both were psychopathic serial killers who targeted Caucasian women, used their charisma as ruses, buried their victims' remains, were arrested after a failed attempt to kill another victim, and had numerous obsessive followers in prison who they seduced and manipulated.

Graham may have been partially based on Kenneth Bianchi, one of the two Hillside Stranglers - Both were psychopathic serial killers who targeted women, lured them with ruses, and both became the object of affection of a woman they became acquainted with while incarcerated, and both manipulated said women into copycatting their crimes by attempting to kill a woman, and both women failed to kill their intended target (although Lancroft did kill some victims while Compton failed to kill any).
