The present results demonstrate that wing shape can be used to identify most species with relatively high success, whereas cross-validation analyses indicated that discrimination between sexes, populations or morphs was less effective, even if significant differences were observed in every comparison. We conclude that wing morphometrics can be a powerful identification tool that might be used in combination with other methods in order to achieve accurate and reliable species identifications-independently of the sex, geographic origin or colour variation of the samples-even with those piophilid species that have been object of frequent misidentifications. This article compares 290 post mortem case reports that were positive for carfentanil. All the cases were submitted to, and analyzed by, the toxicology department of the Office of the Chief Medical Examiner, Edmonton, Alberta, Canada. This study highlights the varied distribution of carfentanil in the body after death as a result of misadventure, i.e., these are accidental drug overdose cases. Post mortem samples were collected from more than one anatomical site and analysed for carfentanil using a validated liquid chromatography-tandem mass spectrometry method. Ante-mortem samples were available in 15 of these cases and were also analysed. Post mortem mean blood carfentanil concentrations were found to be 0.362 μg/L (femoral), 0.442 μg/L (iliac), 0.484 μg/L (cardiac) and 0.692 μg/L (subclavian). The mean vitreous humor carfentanil concentration was 0.238 μg/L; the mean urine carfentanil concentration was found to be 0.697 μg/L. Little difference was found between ligated and 'blindstick' femoral blood carfentanil concentrations. Whilst carfentanil can readily be detected in both vitreous humor and uri
