“…Human sex differences of homicidal behavior is a fairly well established field of research (Jurik & Winn, 1990;Kellerman & Mercy, 1992;Pratt & Deosaransingh, 1997;Wilbanks, 1983), but information on a potential sex-link in homicidal fantasies among males and females is much more limited (Daly & Wilson 1988). More specifically, previous research on homicidal fantasies have focused on the contents of the fantasies, situations in which they arise, triggers, the method of killing, or the real violent act associated with the homicidal fantasy (Crabb, 2000;Duntley, 2005;Grisso et al, 2000;Kenrick & Sheets, 1993), especially in psychiatric patients (Grisso et al, 2000), but not specifically between sexes, emotional reactions and in normal populations.…”
