Physical Fits

Keith Borer Consultants employs physical fit experts that can determine whether two items, recovered seperately, originated from the same source - in the way in which two pieces of a jigsaw fit together.  In many cases it can be of significance.  Most commonly we are asked to look at drugs wraps of foil or cling film or broken implements, pieces of glass or wood. We can compare these microscopically or using polarising light to establish common features which correspond, for example, on their fracture surfaces or in manufacturer’s defects or features.
