Criminal Minds Wiki

The Soul Mates (so named in this wiki) is a pair ephebophilic serial killers, serial rapists, and abductors who appeared in the Season Four episode of Criminal Minds, "Soul Mates".


See William Harris and Steven Baleman's pages.


William and Steven are both anger-excitation rapists incapable of empathy, deriving pleasure from the pain they inflicted on their victims. Unlike most killing teams, which have a dominant and submissive, William and Steven were both dominant personalities and alpha males, which, while rare when it comes to killing duos, is not completely unheard of. Essentially saints in their personal lives, it was the presence of a dark side and feelings of emptiness that drew the two together and made them feel complete. The longer Steven and William get away with their crimes, the stronger their relationship grows, with the two becoming more addicted to rape, torture, murder and each other. Had they not met, the two likely would have continued committing sexual assaults, but may not have escalated to murder.

Real-Life Comparisons[]

The duo appear to have been based on Angelo Buono and Kenneth Bianchi - Both teams consisted of ephebophilic serial killers and rapists who shared predator personalities and were psychopathic sexual sadists, targeted women, tortured their victims before strangling them, and had fights that would eventually lead to their incarcerations.

They may have also been based on Lawrence Bittaker and Roy Norris - Both teams consisted of ephebophilic serial killers, rapists, and abductors who were also sexual sadists, committed crimes prior to their killings, targeted women, abducted, raped, and killed them by strangling them. In addition, in both cases, it was initially assumed that only one person was committing the murders.
