What will be an ideal response?


The three major crime scene functions are overall coordination, forensic services, and investigative services.
Overall Coordination: Ordinarily, this first function is vested in the senior investigator at the scene and she or he will have the final responsibility for what is done at the scene and what types of additional resources will be requested.
Forensic Services: This function is the responsibility of the ranking representative of the department's central crime laboratory or its crime scene processing unit, along with any subordinate specialists who are assigned to the scene.
Investigative Services: Investigative services include interviewing witnesses, conducting and documenting the neighborhood canvass discussed earlier, a field interrogation of the suspect, if in custody, and carrying out and recording the results of a vehicle information canvass.
