The Significance of Class Associations of Footwear Evidence
- Created on Tuesday, 01 May 2012 15:10
Sandy Parent (of the Texas Department of Public Safety Crime Laboratory) presented a poster at the 2009 Trace Evidence Symposium and the 2010 Impression and Pattern Evidence Symposium. This poster has not been published outside of these symposiums (and associated websites which are no longer available), but Sandy has agreed to provide a PDF copy of the poster to SWGTREAD so that it could be posted here as a resource to the community.

Milne, R. The Development of a Wireless Electrostatic Mark Lifting Method and its use at Crime Scenes. Journal of Forensic Identification, 62 (2), pp. 154-164. March/April 2012.
ABSTRACT
This paper outlines the basic principles and practices involved in a technique of electrostatic dust mark lifting (ESL). Details are included about the development of a three-electrode wireless method used in some currently available commercial devices.
Bromophenol Blue as a Chemical Enhancement Technique for Latent Shoeprints

McNeil, K. & Knaap, W.. Bromophenol Blue as a Chemical Enhancement Technique for Latent Shoeprints. Journal of Forensic Identification, 62 (2), pp. 143-153. March/April 2012.
ABSTRACT
The enhancment of two-dimensional shoe impressions, where the matrix is soil, may best be approached using chemistry. Potassium thiocyanate, which reacts with iron particles in soil, is a generally accepted development medium used by forensic investigators. Bromophenol blue, a pH indicator that reacts with carbonates in soil, is used, but with less frequency, particularly in North America. This study compared both chemistries and their ability to enhance two-dimensional shoe impressions deposited from a variety of soil samples on varying substrates. Bromophenol blue, although determined to be an inappropriate enhancement technique for brown paper samples, provided significantly more detailed enhancement than potassium thiocyanate with other tested substrates, including plastic and linoleum.
