Statistical Evaluation of Forensic DNA Mixtures from Multiple Traces
A statistical model for the quantitative peak information obtained from a forensic DNA mixture sample is illustrated on a real case example. We use the combined information from two DNA traces: to find likelihood ratios to quantify the strength of evidence; to deconvolve the mixtures for the purpose of finding likely profiles of unknown contributors to the traces; and to analyse the artefacts that might be present in the mixture after DNA amplification.
