“…On average 32.9% (standard deviation 9.6) of the glass particles produced were deposited backwards towards the person smashing the window pane. As these computations are derived from glass fragment weight, and since the particle size of the glass fragments ranged from tens of millimetres to sub-micron size, exponentially more small particles of glass were produced than large fragments and this is in accord with comments in the published literature [17][18].…”

“…Secondly, once the glass has been transferred to the breaker there is the process of persistence-that is, how much of the glass initially transferred to the breaker remains until apprehension. Considerable effort has been devoted to the study of transfer of glass to clothing and the persistence of that glass (Luce et al (1991); Pounds & Smalldon (1978); Hicks et al (1996);Hoeffler et al (1994); Allen et al (1998aAllen et al ( , 1998bAllen et al ( , 1998c). The results of these purely experimental studies are summarised in the monograph of Curran et al (2000).…”

When examining a sample of glass fragments recovered from a suspect in a forensic case, many questions arise: "Did this man break that window?", "Are these fragments from the crime scene source?", "Do the fragments recovered from the suspect come from more than one source?", "How common is it to find glass on someone unrelated with crime?" etc. Such questions are usually answered with the help of statistical methods. This paper reviews some of the statistical solutions and problems encountered in the interpretation and evaluation of forensic glass evidence.

“…Transfer parameters are very important in a forensic context, in either an investigative or evaluative approach, to assess the evidential value of microtraces at the activity level. Over the years, several studies have been carried out for materials such as textile fibres [1][2][3][4][5][6][7], paints [8,9], glass [10][11][12][13][14] or glitter particles [15,16]. However, there has been a lack of this type of research for soils, although, the last few years, increasing interest in the forensic analysis of soil was revealed as it has sometimes been the only available evidence in some cases [17][18][19][20][21].…”

In criminal activities, soil can be transferred from a crime scene to items linked with a perpetrator; for example, shoes, cars or tools. Several parameters will influence the quantity of soil transferred in a given scenario. The knowledge of the most influential factors can help the expert to assess the evidence using a logical approach at the activity level or to predict the amount of soil that can be expected in a given scenario. The influence of five chosen parameters, namely the shoe profile, shoe size, walker's weight, soil type and soil humidity were assessed using Design of Experiment (DOE) in order to understand their influence on soil quantity transferred on shoes. The Faced Central Composite Design (FCCD) using a quadratic model was found to be highly significant, thus they could be adequately used to model and to interpret the amount of soil recovered from one shoe. These designs demonstrate that the characteristics of the donor (soil type and soil humidity), as well as a combination of these two factors have a very significant impact on the soil transfer. The characteristics of the receptor (shoe profile, shoe size and walker's weight) also have an impact on the transfer but to a lesser extent. Globally, this research provides valuable information for the forensic scientist both in investigative mode: evaluation of the soil quantity possibly transferred on shoes, and in the evaluative steps: is the quantity of soil found on the suspect shoes in accordance to the proposition/scenario given by the prosecution and the defence?
