The value of the evidence depends critically on propositions. In second two papers intended to provide advice community difficult aspects evaluation and formulation propositions, we focus primarily activity level This helps court address question "How did an individual's cell material get there?". order do this, expand framework outlined in first companion paper. First, it is important not conflate results Statements given propositions aim help issues indirect vs direct transfer, time...
Abstract Biological material is routinely collected at crime scenes and from exhibits a key type of evidence during criminal investigations. Touch or trace DNA samples surfaces objects deemed to have been contacted are frequently collected. However, person interest may not leave any traces on surfaces, for example, if wearing gloves. A novel means sampling human air offers additional avenues collection. In the present study, we report results pilot study into prevalence persistence in air....
Selected profiles typed at the Promega PowerPlex 21 (PP21) loci were examined to determine if a linear or exponential model best described relationship between peak height and molecular weight. There fewer large departures from observed expected heights using model. The larger differences that exclusively high weight loci. We conclude data supports use of an curve versus in PP21 profiles. believe this observation will improve our ability for DNA interpretation software.
The hierarchy of propositions has been accepted amongst the forensic science community for some time. It is also that higher up are, against which scientist are competent to evaluate their results, more directly useful testimony will be court. Because each case represents a unique set circumstances and findings, it difficult come with standard structure evaluation. One common tool assists in this task Bayesian networks (BNs). There much diversity way BN can constructed. In work, we develop...
This study reports on the comparison of a standard extraction process with direct PCR approach processing low-level DNA swabs typical in forensic investigations. Varying concentrations control were deposited onto three commonly encountered substrates, brass, plastic, and glass, left to dry, swabbed using premoistened DNA-free nylon FLOQswabs(™) . Swabs (n = 90) either processed IQ(™) kit or, for PCR, swab fibers (~2 mm(2) ) added directly no prior extraction. A significant increase height...
Abstract Forensic DNA interpretation is transitioning from manual based usually on binary decision‐making toward computer‐based systems that model the probability of profile given different explanations for it, termed probabilistic genotyping ( PG ). Decision‐making by laboratories to implement probability‐based should be scientific principles validity and information supports its utility, such as criteria support admissibility. The behind STR mix™ are outlined in this study include standard...
