This article describes a scientifically valid technique for comparing the variability of barefoot impressions.
Abstract
Barefoot morphology comparison is the examination of the impressions of weight-baring areas on the bottom of a human foot. It is carried out when ridge detail is not present so that a link can be established between the bare foot of an individual and an impression found at a crime scene. Barefoot morphology comparisons can be used with care of sock foot impressions or with shoes that have been linked to a crime scene. Comparisons using shoes involves comparing the wear areas on the outsole of the shoe with the inked barefoot impression taken from the suspect. Several cases are described in which barefoot morphology comparisons were successfully made and recent research into barefoot comparison evidence is discussed. The Royal Canadian Mounted Police (RCMP) first began research in the area of barefoot morphology comparison in 1989 when four murders were committed over a 5 month period. The early research of the RCMP showed that bare feet had characteristics that could form the basis for individualization. The authors describe how to collect barefoot samples at a crime scene for comparison and how to collect known samples from individual suspects. The authors recommend taking mold impressions using a foam material from an orthopedic supplier. The comparison method is then explained, which should only be carried out by trained specialists. The method involves taking photographic prints with traced overlays of both the known and the suspect impressions. Class characteristics should be compared first followed by comparisons of the shape and placement of each toe. The examination and comparison of impressions left inside footwear is explained and three case studies are presented to help illustrate the use of the barefoot morphology comparison method. Contact information is presented for further information. Figures, references
