Insects (Diptera) associated with cadavers at the Institute of Legal Medicine in Pernambuco, Brazil: Implications for forensic entomology

The aims of this work was to study the life stages of Chrysomya megacephala in a circular arena allowing the combined radial post-feeding dispersal from the center of the arena of C. albiceps and C. megacephala larvae. To determine the location of each pupa, the distance from the center, the depth and weight of each pupa formed were analyzed. For the larvae of C. albiceps, females released buried deeper than males, reaching an average depth of 10.74 cm and C. megacephala larvae presented greater average results than C. albiceps for all variables, particularly distance, which was 16.02 cm for this species and 12.30 cm for C. albiceps. C. albiceps larvae preyed on 30 C. megacephala larvae in both experiments. These results could be used in forensic entomology because the evaluation of Post Mortem Interval (PMI) was one of the most important aspects of legal medicine, and it could be underestimated if the older dispersing larvae or those that dispersed longer and faster or deeper, were not taken into account.

AbstractThis study highlights the importance of insect evidence by evaluating 949 insect-associated cases, including 139 entomological reports, from 2001 to 2019 at the Institute of Legal Medicine Frankfurt/Germany. With a high number of cases in the summer months and a low number in the colder season, 78.5% of the bodies were found indoors, regardless of year or month. In more than 80% of the cases, where PMI information was available (n = 704), the presumed PMI ranged from 1 to 21 days, a period during which entomological evidence can provide a day-specific estimate of PMImin. In cases where insects have been identified to species level (n = 279), most bodies were infested by one or two species with a maximum of 10 different species. Overall, a total of 55 insect species were found. Information on biology, activity and distribution of the most abundant taxa is given and applied for 5 case histories estimating different PMImins of up to over 6 months. Despite proved importance and scientific development of forensic entomology, insects are still rarely considered as a tool in forensic case work. The main reasons are a lack of awareness and (too) late involvement of a forensic entomologist. Our work shows that forensic entomology is an independent discipline that requires specialist expertise.

In the summer of 1979, a group of experts on law, medicine, and ethics assembled in Siracusa, Sicily, under the auspices of the International Commission of Jurists and the International Institute of Higher Studies in Criminal Science, to draft guidelines on the rights of persons with mental illness. Sitting across the table from me was a quiet, proud man of distinctive intelligence, William J. Curran, Frances Glessner Lee Professor of Legal Medicine at Harvard University. Professor Curran was one of the principal drafters of those guidelines. Many years later in 1991, after several subsequent re-drafts by United Nations (U.N.) Rapporteur Erica-Irene Daes, the text was adopted by the U.N. General Assembly as the Principles for the Protection of Persons with Mental Illness and for the Improvement of Mental Health Care. This was the kind of remarkable achievement in the field of law and medicine that Professor Curran repeated throughout his distinguished career.
