"When we talk about organized versus disorganized killers, it has more to do with premeditation than what you'd normally associate those words with. An organized killer plans ahead, usually taking time to study their victim and fantasize about the act before making it into reality, whereas a disorganized killer is more ruled by the moment. For instance, a messy crime scene would point towards a disorganized killer while a victim that has been tortured before death would belong to an organized UnSub."
