Bloodstain evidence has become a deciding factor in the outcome of many of the world's most notorious criminal cases. As a result, substantiation of this evidence is crucial to those on either side of the courtroom aisle. The challenge is to obtain an authoritative reference that provides the latest information in a comprehensive and effective manner. Bloodstain experts routinely carry out interpretation of bloodstain patterns at scenes of violent crime and on items of clothing taken from suspects or victims. In addition we can examine witness statements and CCTV footage and help to determine if a person has been active in an assault.
