Documenting Crime Scenes Target 1 2 Monday September

Documenting Crime Scenes Target 1 -2 Monday, September 18, 2017

Target 1 -2 I can document a crime scene by identifying, labeling, and sketching evidence.

Crime Scenes • Primary Crime Scene – Where the actual crime took place – Ex) a mugging took place on a sidewalk • Secondary Crime Scene – A location other than the primary crime scene, where important evidence is located – Ex) a suspect’s home or car – Ex) a location where a body was dumped

Documenting a Crime Scene 1. Scan and isolate the scene – The “scene” must contain all the evidence – Keep the scene safe from outside influences (people, weather, vehicles, etc. ) 2. Photograph the scene and all evidence – Keep evidence in its original location – Use rulers in photos to record size and shape 3. Take notes and measurements (rough sketch) 4. Draw a scaled crime scene diagram

Crime Scene Diagrams • Must be drawn to scale • Must show: – Doors, egress windows – Large furniture/obstacles – Evidence – Victim(s) • Must have a key • Must record date, time, and artist

Labeling Objects • All objects and evidence must be labeled and keyed • Use rectangles and circles to show locations of obstacles (furniture and large objects) • Use letters to label obstacles AND to show locations of evidence • Use the same letter and add numbers for multiple objects – Ex) multiple blood drops could be A 1, A 2, A 3, etc
