“…Following their work, numerous studies have been carried out to investigate the evidence dynamics of a number of different forms of trace materials, such as glass [11][12][13], paint [14][15][16], hair [17][18][19] and pollen [4,20,21]. Similar patterns of loss to the two-stage model outlined by Pounds and Smalldon [9] have been shown in these studies; for example Bull et al [4] determined a significant loss followed by a slower decay for pollen grains. Their study also showed that the decay was more influenced by the recipient material than the particle type when conducting experiments using pollen grains, powder and metal particulates.…”

“…The first experimental studies undertaken to understand the evidence dynamics of forensic traces evidence were carried out by Pounds and Smalldon [8][9][10], who investigated the transfer, persistence, and the mechanisms involved during the transfer of fibres between items of clothing. In their initial study involving the transfer of textile fibres to wool and acrylic clothing [8], they determined that both the fabric type of the recipient garment and the force of contact affect the amount of fibres transferred, so that high pressures and coarse recipient garments lead to the transfer of shorter fibres. In a further study exploring the persistence of transferred fibres [9], the authors determined that the loss of transferred fibres from the surface follows an exponential decay, with a rapid loss initially followed by a subsequent slower loss.…”

An initial loss of approximately 80% was observed after 4 h, which increased to around 95% after 24 h.…”

Sexual assault is a serious crime that often has low conviction rates. Recent literature has demonstrated that there is potential for fragrances to be valuable in forensic reconstructions where there has been contact between individuals. However, developing appropriate evidence bases for understanding the nature of fragrance transfer in these contexts is needed. This article presents three experiments that address the transfer process of fragrances that have been transferred from a primary piece of fabric onto a secondary piece of fabric, in a manner that could occur during an assault. The three variables studied were the ageing time of the fragrances on the first fabric prior to transfer, the contact time between the two fabrics, and lastly the fabric type (of the primary material and the recipient material). The transfer was evaluated using a validated solid phase micro-extraction gas chromatography-mass spectrometry (SPME GC-MS) method. The findings demonstrated that all three variables had an impact on the transfer of fragrances between clothing fabrics. Generally, lower volatility compounds were transferred and recovered in larger amounts than higher volatility compounds. All fragrance compounds were successfully recovered from a secondary piece of fabric even when the contact time was as short as 10 s, and even when the perfume was aged on the primary fabric for as long as 48 h. The nature of the fragrance transfer also depended on the fabric type, so that a clear discrimination was observed between the fragrance transfer that occurred onto a natural fabric (cotton) and onto a synthetic fabric (polyester).

“…As outlined in Section 1.2, understanding how physical traces interact with the physical and human environment is critical for identifying where traces are likely to be present and under what circumstances, which is important for the reconstruction of events. Empirical studies addressing the transfer and persistence of trace materials have developed since the early work of Pounds and Smalldon () (fibers), Brewster, Thorpe, Gettinby, and Caddy () and Hicks, Vanina, and Margot () (glass), and Morgan et al () and Bull, Morgan, Sagovsky, and Hughes () (general particulates). There is now a growing body of published work that addresses a wide range of different physical traces (Bitter, (smoke residues), Maitre et al, (GSRs), Palmer, Sheridan, Puckett, Richardson, & Lo, and Slot et al, (fibers), Levin, Morgan, Scott, & Jones, (diatoms), Morgan, Scott, Ainley, & Bull, (soils) Morgan, Flynn, et al, , and Morgan, Allen, King, & Bull, (pollen)).…”

Crime reconstruction takes place in a complex ecosystem and needs to be responsive to the context of each case. For accurate, reproducible and transparent crime reconstructions to take place, a holistic approach is needed that considers the different stakeholders, different types of trace material, integral human decision-making and interconnected nature of the forensic science process. For robust reconstruction, there needs to be a consideration of both the distinctive types of trace material that can contribute to the reconstruction, and an understanding of the interplay of human decision-making within reconstruction approaches. In addition, it is also necessary to consider source attribution of a trace material in addition to the activities that led to the generation, identification, transfer, and persistence of the trace. This requires explicit and tacit forms of knowledge, and an incorporation of the inherent uncertainty and risk in the reconstruction approach. The communication of conclusions reached in a crime reconstruction that address what the evidence means is also an important consideration given the different requirements of intelligence and evidence. Therefore, undertaking a crime reconstruction within a holistic framework that seeks to incorporate the complexity of the forensic science ecosystem is valuable for achieving a problem solving approach that offers reproducible, transparent reconstructions with a clear articulation of risk and uncertainty that can be of value to investigators and the courts.

“…For years now, studies highlight that fibers from the perpetrator are transferred onto the victim during the criminal action and conversely [1][2][3][4]. The number of textile fibers recovered depends notably on the characteristics of the different substrates (shedding capacity of the donor and structure of the recipient), the type of contact and the phenomenon of persistence [3][4][5][6][7]. These are parameters that should be discussed when reasoning at the activity level [8][9][10].…”

Was this group of target fibers transferred during a criminal action? Is it possible that it was transferred during another legitimate activity? Acquiring knowledge about the activity, whether legitimate or criminal, leading to the transfer of a group of fibers is a recurring challenge encountered throughout the evidence interpretation process. Trace evidence such as fibers may assist with generating a reasoning of the activity which produced the trace, but this assumes that one already has a thorough understanding of the transfer phenomenon. How to generate and then use such relevant knowledge? What are the influencing parameters and which ones should (or can) be controlled? The present work focuses on homicides by smothering using a pillow and the transfer of fibers on the face of the victim in such events. A legitimate activity - represented by a night's sleep on a pillow - was also investigated since such legitimate, alternative explanations concerning the presence of fibers could likely be formulated by the suspect. The number and distribution of fibers transferred onto the victim's face in either scenario were investigated and interpreted using a Bayesian approach. Results showed that the shedding capacity of the pillowcase strongly impact the number of fibers recovered. The nature of the action, modus operandi and amount of friction could not be excluded in their influence on the transfer of fibers. Finally, likelihood ratios indicating the number of fibers recovered from the victim's face can provide relevant information by supporting either criminal or legitimate proposition (i.e., smothering or night's sleep scenario).
