We have worked on countless cases for both the prosecution and defence and using the latest GSR techniques are able to offer a comprehensive service on clothing, firearms, swabs from cars and other items.

When a gun is fired, microscopic particles from the fired ammunition are always ejected and can be deposited either on the firer, anyone who is in the close vicinity and other items.

We can:

  • Review the analysis and interpretation of gunshot residue to determine if a suspect may have fired a particular firearm, ammunition type or has been close to the discharge of a firearm and been inadvertently contaminated; including the review of the analysis of:
    • Propellant


    • Firearms


    • Clothing


    • Cartridge Cases


    • GSR Swabbings


  • Production of expert reports and presentation of witness testimony

Tool Marks

Forensic Scientific is able to utilise our extensive experience to resolve any issue that you may have involving Tool Marks. We have worked on countless cases for both the prosecution and defence and will undertake re-examinations of the item/s in question as well as reviewing work already carried out to compare the area of damage with the items submitted for comparison.

When an offence is committed using a tool or instrument, such as screwdrivers, crowbars, bolt cutters, knives etc, that item will usually have damage or wear individual to only that item. It is this damage or wear that can provide a unique link between the item and the mark it has left at the scene of the crime or upon the victim. The ability to be able to find and identify a unique mark takes years of training and experience; the work is painstakingly thorough and can take considerable time and effort to undertake.

As the specialism of Tool Mark examination takes many years to acquire it is not uncommon for unexperienced examiners to misinterpret marks that are not unique to the actual instrument in question. We therefore always take this into consideration when interpreting the prosecutions results.

Our review and analysis of cases involving tool marks includes:

  • Re-examining the marks left at a crime scene and the item which allegedly made it, making a comparison to see if a positive match is present; using macroscopic and microscopic conclusive techniques


  • Re-examining other items seized but excluded at the time


  • Ensuring that the scene marks and control marks made with the item/s in question were examined for the presence or absence of features such as manufacturing defects and random damage


  • Ensuring that in the absence of any unique features in the mark the examiner thoroughly decided on the strength of evidence based on the quality of the mark and the commonness of the instrument


  • Production of expert reports and presentation of witness testimony
