Some sex-linked killers feel a deep resentment against their mothers. This is often for their treatment in the family, as in harsh punishment and/or favouring siblings. In turn, the resentment fuels a corresponding hatred against women. John Crutchley was a suspect in a number of lust killings, but ws never found guilty. However, his sexual turn on was to abduct women and remove blood from them. Henry Lee Lucas exemplifies a particularly toxic development creating the circumstances for killing. Bobby Joe Long suffered damage to his head, which might well have involved brain damage and harmed his development. He appears to have developed a hatred towards women as a result of what he perceived to be his mother’s immorality. Carroll Edward ('Eddie') Cole shows a similarly based resentment towards his mother. Articulate heterosexual killer Edmund Kemper was harshly treated in his family, particularly by his mother.
