Complex planned suicide is characterized by the simultaneous use of two or more methods to ensure that death occurs even if one method fails. The authors present an original combination of two self-killing methods. A 42-year-old cardiologist, with a major depressive syndrome and several suicide attempts, as well as cocaine addiction, was found dead at his home with a femoral catheter inserted in the right femoral artery. The autopsy concluded that death was due to major hemorrhagic process in a context of suicide. Toxicological analyses, performed in peripheral blood by gas chromatography coupled to mass spectrometry and by liquid chromatography-diode array detection, revealed the presence of ethanol (0.13 g/L), cocaine, and metabolites (cocaine: 432 µg/L, benzoylecgonine: 3286 µg/L, ecgonine methyl ester: 1195 µg/L, cocaethylene: 41 µg/L), a potentially lethal concentration of citalopram (1.03 mg/L), toxic concentrations of hydroxyzine (0.11 mg/L), bromazepam (2.06 mg/L), and lidocaine (7.30 mg/L). At the end of these analyses, the death was reclassified as planned complex suicide combining drug intoxication and catheterization of the femoral artery. The authors discuss the main aspects of this case and stress the importance of meticulous analysis of all available evidence: witness reports, victim's medical history and occupation, findings of at-the-scene examination, autopsy, and toxicological analyses, in order to exclude homicide and to understand the sequence of events that led to death.
复杂计划性自杀的特点是同时使用两种或多种方法,以确保即使一种方法失败,死亡也会发生。作者提出了两种自杀方法的原创组合。一位 42 岁的心脏病专家,患有重度抑郁综合征和多次自杀企图,以及可卡因成瘾,被发现死在自己家中,右侧股动脉插入一根股动脉导管。尸检结论为自杀导致大出血过程中死亡。通过气相色谱-质谱联用和液相色谱-二极管阵列检测在外周血中进行的毒理学分析显示,存在乙醇(0.13 g/L)、可卡因及其代谢物(可卡因:432 µg/L、苯甲酰可卡因为:3286 µg/L、ecgonine methyl ester:1195 µg/L、可乐因:41 µg/L)、西酞普兰的潜在致死浓度(1.03 mg/L)、羟嗪(0.11 mg/L)、溴马唑仑(2.06 mg/L)和利多卡因(7.30 mg/L)的毒性浓度。在这些分析结束时,死亡被重新归类为结合药物中毒和股动脉导管插入的复杂计划性自杀。作者讨论了这个案例的主要方面,并强调了仔细分析所有可用证据的重要性:证人报告、受害者的病史和职业、现场检查、尸检和毒理学分析的结果,以排除他杀并了解导致死亡的事件顺序。
