Abstract Background As far as we know, no previous research has investigated child homicide in Tunisia. In this context, our study was carried out to analyze the epidemiological and medico-legal characteristics of child homicide occurring in northern Tunisia over a 17-year period. Results Eighty-seven cases were collected, with a male-to-female ratio of 2.4. The mean age of the victims was 12.6 years for both sexes. We found that 56.3% of the cases were aged between 15 and 18 years. The majority of deaths under 15 years of age occurred at home as a result of intrafamilial homicide. Victims aged more than 15 years were more likely to be assaulted outside the home by a non-family member. The most frequent method of homicide was sharp force (39%) affecting mostly the heart and the lung, followed by blunt trauma (25%), which affected mainly the head. Sexual assault was diagnosed at autopsy in six victims (6.9%). Conclusions The study offers available data concerning the patterns of child homicide in northern Tunisia and may help to implement preventive measures against this kind of crime.

Abstract Delusional misidentification syndromes are associated with danger and may lead to homicide. Early assessment of the danger is a key part of the psychiatric examination. Compliance to treatment in psychosis is important to avoid the devastating consequences, for the perpetrator, the victim, and the community.

Abstract Background Death by strangulation is a violent and frequent method of homicides. Strangulation is rarely accidental due to ligature which is caused by a wide variety of objects such as cords, ropes or clothing articles (scarves). It concerns mostly accidents at work, rarely road traffic accidents and domestic ones. We report four cases of occupational and accidental strangulation causing death. Case presentation In our cases, the ligature link was a scarf or a towel. The link was caught on the belt of a tractor in two cases: on a drill pipe and on a combine harvester. Death occurred on site in three cases. The external examination has marked an asphyxia syndrome associated with a large strangulation mark. Furthermore, the autopsy findings have revealed large ecchymotic infiltrations of the neck muscles, a rupture of the trachea, and the oesophagus with a disjunction of cervical vertebra with a contusion of the spinal cord. Conclusions The ruptures of the trachea, oesophagus and cervical vertebra are not classic strangulation lesions but are explained by the brutality and violence of the traction exerted on the neck. We highlight the importance of preventive measures in this accidental type of deaths.
