Solving a crime

First a criminal psychologist must determine

1. Antecedent: What fantasy or plan, or both, did the murderer have in place before the act? What triggered the murderer to act some days and not others?
2. Method and manner: What type of victim or victims did the murderer select? What was the method and manner of murder: shooting, stabbing, strangulation or something else?
3. Body disposal: Did the murder and body disposal take place all at one scene, or multiple scenes?
4. Post-offense behavior: Is the murderer trying to inject himself into the investigation by reacting to media reports or contacting investigators?

This will build the profile of the offender, and ultimitly aid in the aprehenstion of the criminal.
