Abstract

Modern visualisation techniques offer great opportunities for visualising trace evidence, both fingerprint and footwear impression evidence. However, in the case of the latter, opportunities presented by these techniques are used only to a small extent. This article is addressed to forensic technicians and experts in the field of footwear impression evidence and fingerprints examination. It aims to present and organise information about contrasting, visualising, and collecting the most common footwear impression evidence: three-dimensional impression, impressions of dry origin (i.e. left with dust) and of wet origin (i.e. left with mud/soil, blood or urine) on various types of surfaces. The authors hope that the expertise collected in this article will help increase the number of visualised and collected footwear impression evidence.
