Modern day criminal investigation has reached a point of sophistication requiring the involvement of many different disciplines to solve a crime. Each discipline inserts a part of the puzzle until it is complete. It is important to understand what each forensic expert has to offer. The coroner or medical examiner, asking for input from the various experts until enough information is received to determine the cause and manner of death, is usually the keystone to a death investigation. This information is then shared with the police investigators and prosecutor. This calls for the utmost cooperation and communication among those involved.
