A planned complex suicide by self-stabbing and vehicular crash: An original case and review of the literature.

Suicide is a frequent manner of unnatural death, especially from a forensic point of view. Complex suicide is defined as a recourse to more than one potentially lethal mechanism to deliberately induce death. This paper presents a complex suicide with a novel combination of self-killing methods. A 27 year-old man, working as a butcher, was found dead in his crashed car. The facts were initially in favour of an obvious traffic accident until a knife was discovered penetrating the driver's chest, requiring the police who were on the scene to carry out a criminal investigation. The cause of death was a major hemorrhagic process due to vascular thoracic lesions and internal blood loss. Based on the circumstances surrounding the death, the police investigations and the findings at the autopsy, the case was classified as a planned complex suicide. Through this original combination of two methods of suicide, this paper underlines the significance of a complete criminal investigation supported by a detailed crime scene inspection and autopsy examination.

A Rare Case of Poisoning with a Volatile Substance: Quantitative Determination of n-Butane in Postmortem Tissue.

Poisoning with volatile substances remains exceptional. Authors report the case of a married couple who were found in a car with a butane gas bottle: the woman was dead and her husband alleged it was an unsuccessful suicide pact. A specific research of volatile substances on postmortem samples with headspace gas chromatography-mass spectrometry following a quantitative determination was performed. The n-butane concentrations detected were composed of 610 µg/L (cardiac blood), 50 µg/kg (brain), 134 µg/kg (lungs), 285 µg/kg (liver), and 4090 µg/kg (heart) and were compatible with the rare lethal concentrations evoked in the literature. The cause of death was determined to be asphyxiation through n-butane criminal poisoning. Authors recommendation therefore is to take samples immediately and place them in properly sealed containers and hence analyzing the samples as soon as possible after collecting them or storing them under -30°C (-22°F) if analyses cannot be performed immediately.

Severe craniocerebral trauma with sequelae caused by Flash-Ball® shot, a less-lethal weapon: Report of one case and review of the literature.

The use of Flash-Ball® as a non-lethal weapon by several special units within the police and police forces started in France in 1995. Little literature is available concerning injuries caused by Flash-Ball® shooting. However, we report the case of a healthy 34-year-old male victim of a Flash-Ball® shooting during a riot following a sports event. This young man presented serious craniocerebral injuries with a left temporal fracture, moderate cerebral oedema, fronto-temporal haemorrhagic contusion along with an extra-dural hematoma and subarachnoid hemorrhage requiring neurological and rehabilitation care for two months leaving important sequelae. Although the risk is obviously lower than with firearms, Flash-Ball® is nonetheless potentially lethal and may cause serious physical injuries, particularly after a shot to the head.
