Bones found by chance can be of great criminal or historical interest. The nature of their appraisal depends on the individual case, the locally effective legislation and the available resources. To assess whether a find is relevant with respect to criminal investigation, the circumstances of the find and the results of the forensic examination carried out by trained personnel must be considered. The aim of this study was to obtain an overview of the circumstances and nature of the finds as well as the results of the subsequent expert opinions by evaluating bone finds from the federal state of Hesse, Germany. For this purpose, over a 10-year period from 2011 to 2020, all bone finds examined at the Institutes of Legal Medicine in Gießen and Frankfurt am Main, Germany, were evaluated retrospectively with regard to the locations and circumstances of the finds, their nature (human or non-human), the postmortem interval, possible traces of violent impact and the results of further examinations. Of the 288 bone finds evaluated, 38.2% were found in forests, meadows and parks. In 50.7%, the finds contained human bones, of which 37.0% had a forensically relevant postmortem interval of 50 years or less. Evidence of trauma was described in 77.4% of the human bone cases: postmortem damage in 78.8%, peri-mortem injury in 9.7% and ante-mortem injury in 11.5%. DNA examinations were performed in 40.4% of the human bone finds. They yielded STR profiles in 81.3%, leading to a definite identification in 35.4%. Among the non-human bones sent in, the most common were bones from pigs (23.4%), deer (18.1%), cattle (16.4%), roe deer (11.7%) and sheep (11.7%). The macroscopic examination is the first step of the forensic-osteological evaluation and sets the course for further examinations or investigations. DNA examinations are of great importance for the reliable identification of human bones. They were responsible for 70.8% of successful identifications. [ABSTRACT FROM AUTHOR]
