Journal ArticleDOI
TL;DR: There seems to be no satisfactory way for an expert witness to address the question of uniqueness in court: if there is overwhelming non-DNA evidence that the defendant is not the source of the crime stain, then that is also overwhelming evidence of non-uniqueness.

Journal ArticleDOI
TL;DR: It was found that fibres were transferred with the normal activity of a car passenger and carpet type and shoe sole parameters were significant determinants in the number of fibres that transferred.

40 citations


Journal ArticleDOI
TL;DR: Experiments in which the combustion of animal tissue (pork) was measured under a variety of conditions that may be encountered in fire scenes found that the presence of other, less efficient fuels and the absence of large fuel masses results in significantly smaller fires.

35 citations


Journal ArticleDOI
TL;DR: The California Association of Criminalists' Founders' Lecture as discussed by the authors was the first one to address the importance of scientific information exchange, the development of a code of ethics, and the leading of certification effort.

Journal ArticleDOI
TL;DR: This paper reviews the studies so far reported in the literature on firearms identification applied to consecutively (or closely) manufactured components of a firearm.

Journal ArticleDOI
TL;DR: This paper describes a simple processing and analysis scheme for explosives trace swab samples which deals both with organic and inorganic materials.


Journal ArticleDOI
TL;DR: In this paper, a method for inference in a case where the true father may be a relative of the alleged father is described and it is reported that most current methods overstate the probability that the allegedFather is the father.

Journal ArticleDOI
TL;DR: The characteristics of modacrylic fibres are described and includes over 80 samples (previous and current) representing 15 trade names and include unusual optical and morphological features which are a strong indication of their generic class.


Journal ArticleDOI
TL;DR: In this study, the authors show that cats and dogs have tandemly repeated sequences in their mtDNA control region that are very polymorphic but are also the source of a very high level of heteroplasmy.


Journal ArticleDOI
TL;DR: A portable case has been developed by which cyanoacrylate (super glue) fuming can be used inside a vehicle suspected of being involved in serious crime.

Journal ArticleDOI
TL;DR: An account is presented of a simple method for the detection of ACP using gas chromatography with mass selective detection (GC/MS) which will facilitate detection of zopiclone use as part of a routine screen.



Journal ArticleDOI
TL;DR: The Fx5 Fibre Finder has been developed by Foster & Freeman Ltd to automatically search tape lifts for coloured fibres specified by the operator to be a valuable labour saving device in forensic textile examination.


Journal ArticleDOI
TL;DR: In this article, the authors used PGM and EAP blood grouping systems and detected a mixture of blood on the deceased's jacket during a murder enquiry, however, proved that only a single source of DNA matching the deceased was present.


Journal ArticleDOI
TL;DR: The relative bit density variation graphs of 207 specimen credit cards processed by 12 encoding machines were examined first visually, and then classified by means of hierarchical cluster analysis, which provided a high accuracy of identification with all 29 'questioned' samples classified correctly.


Journal ArticleDOI
TL;DR: The paper analyses responses to different explanations of the value of DNA evidence using a likelihood approach, which is more consistent with a Bayesian analysis than one based on a frequentist approach.
