"The suspect is likely a white male, in his late twenties to late thirties. He likely is not a college graduate, but feels nonetheless superior to those with advanced education, and is likely employed in a bureaucratic entity, possibly civil service or quasi-public service, from which he feels alienated. He has a problem with authority and a deep-seated resentment of those who he feels have impeded his progress professionally. [...] The suspect has trouble with lasting relationships and is possibly a high-functioning alcoholic with alcohol being utilised as a trigger in the commission of these crimes. His resentment of the homeless may stem from a personal relationship with someone who is in that cohort, or his victimisation of vagrants might merely represent an opportunity for the killer to assert his superiority and intellectual prowess."
