they usually do this with some type of physcological gratification (unusual behavior or emotion)
the killings are mostly a part of sexual release evidence is collected from the crime scene including photos, physical evidence, investigator notes and reports of witness interviews. the evidence is organized, studied and analyzed to look for patterns that can link to the crime and the unsub criminal profilers attempt to recontruct the crime scene and put themselves in the shoes of the killer and they use a timeline of events steps 1-3 are combined to create a criminal profile including the intentions, physical qualities, personaltiy and behavior of the perpetrator. the profile that was just made is given to the investigators that work where the crime happened who are helping with this case. if more leads turn up when investigating more, the profile may be changed to fit the unsub. in about 50% of the cases a suspect is identified. If and when this happens, he/ she is interviewed and compared to the profile. If there is a reasonable suspicion that the suspect could be the perpetrator, than a warrant is issued for their arrest.
