SUMMARY Frequently, when a crime is committed, fibres are left at the scene. This paper examines the modelling aspects of evaluating the evidential content of such fibres by using a Bayesian approach. Inferences are made via the likelihood ratio, derived from bivariate colour measurements. Modelling the distribution of colour within a particular garment is discussed in detail. In addition, a large database allows an empirical prior distribution to be incorporated, utilizing kernel density estimation. Data from actual casework are analysed.

“…Single textile fibers can be an essential form of trace evidence, and characterization of evidential fibers has been accomplished by examining fiber composition, 1–4 fiber dye structure, 5–7 color, 8 absorption, 9 Raman signal, 10 and fluorescence. 11,12 Identification using such characteristics is essential since forensic fibers can be transferred and subsequently examined to discover common origins.…”

Discovering common origins of trace evidential textile fibers can be a challenging task when fiber structure or dye composition does not provide exclusive identifying information. Introduction of new chemical species after mass production and distribution of a textile may be exploited to trace its history and identify the origin of its fibers. In this article, fluorescence microscopy is used to examine the alteration in the fluorescence spectral fingerprint of single fibers resulting from exposure to commonly used detergents that contain fluorescent whitening agents. Dyed acrylic, cotton, and nylon fibers were laundered and the spectral contribution of the detergent on single fibers was quantified and shown to reach a maximum after five sequential washes; some detergents showed statistically meaningful differences to fiber spectra after only a single wash. Principal component cluster analysis was used to determine that the spectra of laundered fibers are distinct from the spectra of dyed, unwashed cotton or nylon, but not acrylic, fibers.
