Toolmarks

Another none-to-frequently encountered type of forensic evidence entails the comparison of toolmarks or striation marks on items such as cut chains or wire and abrasions on painted or metal surfaces.

The cutting edges of certain tools such as bolt-croppers or jemmys usually bear unique cuts or deformations, which are a consequence of their everyday use. These marks can be imparted to a surface with which they come into contact. Indeed, these markings can often be so unusual that they lead to a unique association being formed between tool and scene.

Bericon offers expert scrutiny of such marks and an independent assessment as to the likelihood that a particular tool or implement was responsible for any damage or cut.
