Crime Scene Reconstruction Services
Crime scene examination and subsequent reconstruction depends on locating valuable information. This may be on the deceased or injured person or persons, blood, bullets, firearms, bloodspatter patterns, shoe impressions or clothing. No single school on crime scene investigation will prepare a person for this type of investigation. It also requires experience. The combination of education in scientific method, inductive reasoning and experience is invaluable in an examination of a scene. For example, an area of a crime scene may be tested with a reagent such as Luminol to locate blood. A positive area was swabbed and later tested by DNA to be that of your client. Luminol is a screening test, it does not confirm the presence of blood and the test may be positive with non-blood, non-human substances. The source of the DNA found could be semen, saliva or sweat. Do not assume that someone tested for those items.
Pex Forensic Consulting has it’s own laboratory that conducts specialized examinations on physical evidence. Since many of the cases in which we are retained involve a death. It is not uncommon to have firearms related evidence. Any time a Crime Laboratory identifies a bullet or cartridge case to a particular weapon, it is important to seek confirmation. A match of a bullet or cartridge case to a firearm is direct evidence, just like a fingerprint is direct evidence. Some of the most important cases, however, often are those where the report states the bullet is too badly damaged for comparison or the result was inconclusive. Pex Forensic Consulting has successfully matched bullets that were reported inconclusive by another crime laboratory. We have also encountered situations were an inclusive result was indeed, an exclusion.
For Pex Forensic Consulting, review of reports and consultation with attorneys and investigators represents approximately 90% of our work. Most cases begin with a discovery packet that would contain, crime scene reports, investigator’s reports, lab reports, autopsy reports and any available photographs. We always request the laboratory notes also. These notes often contain information that was not placed in a final report. Any in-lab photographs must be discovered as a Laser copy or other high quality image. We do not accept Xerox quality photo images. We receive documents as .PDF files, Microsoft Word, or hard copies. We prefer photographs on disc, but also accept generic prints. After review, salient information is entered into Casemap Software. Time Map Software may also be used to establish time lines if relevant to the issues. Contact is made with the attorney or a member of his team. This may be by e-mail, telephone or in person.
