Crime Scene Reconstruction

Crime Scene Reconstruction is the process of taking all available information, with a focus on physical evidence, to determine the facts and circumstances surrounding a crime, a suicide, or an accident. The crime scene reconstructionist seeks to answer the following:


Proper crime scene reconstruction is conducted in three phases:

  1. Investigation: the crime scene is examined and documented to determine what evidence is present without consideration to the particular meaning of any of the evidence.
  1. Analysis: individual items of evidence, or groups of related evidence, are examined to determine their individual significance without respect to how those items fit into the overall reconstruction of the crime.
  1. Reconstruction: all evidence, including testimonial and documentary evidence, is taken into consideration to determine how the crime took place.

Gillespie Investigations can provide a variety of crime scene reconstruction services including bloodstain pattern analysis, shooting incident reconstruction, fingerprint evidence collection, collection of blood and biological evidence for submission to a DNA laboratory; search for trace and biological evidence, photograph and videotape scenes and physical evidence; and create diagrams of crime scenes.


Fingerprints may be present on many surfaces, and, in many instances, can be discovered, processed, and lifted in an effort to determine the origin of the print. Gillespie Security Services has the expertise and ability to recover prints in an effort to identify/determine the origin of the print. Once a print(s) are recovered, they can analyzed by a latent print examiner and compared to known prints to determine a match.

DNA evidence can hold the key to unlocking many answers. If you have an item that you suspect may contain DNA it is possible to:

  1. Test that item to determine if DNA evidence is present,
  2. Create a DNA profile of the DNA sample, and
  3. Compare the DNA profile with a known DNA sample to determine the origin of the DNA.
