Crime Scene Reconstruction involves knowledge of crime scenes, crime scene investigation, blood stain pattern interpretation, evidence analysis, and familiarity in interpreting autopsy reports. Crime scene reconstruction experts must work closely with medical examiners, firearm experts, criminalists, and other related experts.

The challenge of reconstructing a scene the amount of movement in that scene. It can be impossible to know the exact sequence of events and movements made by the suspect(s) and/or victim(s) but with the help of the scene photos, sequence of events can be established. Crime scene photos capture details that lend to establishing actions and reactions found in the form of evidence.

Remember these photographic tips:

  • Photographs of pattern evidence, such as bloodstain patterns, should be taken with the digital film plane parallel to the pattern surface. Include an L-shaped scale in the photographs.
  • Document/photograph the ceiling and the walls in the vicinity of the victim’s body.
  • Photograph areas void of blood.
  • Photograph victim(s) in their original position taken from various angles
  • Photograph area under the victim’s body and under any other large moveable objects.

Various questions must be asked to help aid in reconstructing a crime scene:

  • What does the evidence say about the scene?
  • Are the suspect’s statements consistent with the evidence?
  • Are the victim’s statement consistent with the evidence?
  • Is this a homicide, suicide, or self-defense?
  • Is the witness a suspect?
  • Were there any attempts to clean up the scene or alter the evidence?

Information gathered from scene photos, crime scene sketches, witness and victim statements, suspect statement, and documented evidence can help detectives, crime scene investigators, and other related personnel create a timeline of events. This will help tell the story of how a scene progresses to its end.
