Forensic age estimation at the University Center of Legal Medicine Lausanne-Geneva: a retrospective study over 12 years.

With the undeniable increase in asylum requests from unaccompanied alleged minors, age estimation of living individuals has become an essential part of the routine work in European forensic centers. This study aims to review the forensic age estimations performed in our center since 2010, to evaluate the state-of-the-art of this practice in Switzerland with the evolution of the methodology according to upcoming recommendations. Our institute's expert reports performed between 2010 and 2022 were retrospectively analyzed. We gathered the following parameters: demographic data, morphological characteristics, alleged age compared with the assessed minimum age, sexual maturation, dental and bone age. When available, we collected personal and family history, medical history, records of torture-related/self-inflicted injuries, and information about eating habits that might affect skeletal development. Data collection amounted to 656 cases. Forensic age estimations ordered by the Swiss Secretariat for Migration (SEM) represented 76.4% of cases, with 23.6% of them ordered by the Court/Public Prosecutor. Most alleged minors were male (94.5%) and came from Afghanistan (53.4%). Adjunction of CT scans of the sternoclavicular joints was necessary in 86.4% of cases. Only 25.2% of our reports concluded on most probable minority, with 55.6% of definite majors; in 19.2% of our cases, minority could not be excluded. This study aspires to further broaden our expertise regarding forensic age estimations. Given the increasing migratory flows, we can expect a notable increase in the frequency of these requests. Consequently, this study aims to promote a multidisciplinary approach and the international standardization of the methodology of these estimations.

Skate or die: Unusual circumstances surrounding a natural cause of death.

In a forensic pathologist's mind, a suspicious death scene involving inflicted injuries and a weapon always raises three possible hypotheses regarding the manner of death-homicide, suicide, or accident; the latter is slightly less common. We present a case of a 43-year-old homeless man with a history of chronic alcohol abuse who was found dead in a skate park in Geneva. He was inflicted with a stab wound to his abdomen, with a knife found in situ. With the suspicion of homicide, a crime scene investigation team, including a forensic pathologist, was summoned to the scene. However, further examination of the body revealed a deep cut with hesitation marks on the left forearm. This discovery raised the hypothesis of a suicide. Here, we have described the investigations made by the police and forensic department, along with the circumstances and autopsy findings that determined the cause of death as an effect of a natural disease.
