This case concerns an unusual suicidal plastic bag suffocation. An elderly white man was found dead and partially disrobed in his apartment lying supine on a sofa with a plastic bag closed by a rope over the head and the upper and lower extremities tightly tied with two other ropes, the end of both arranged into slipknots (self-rescue mechanism). Police investigations found no pornography in the apartment, and circumstantial data alleged no psychiatric disorders or suicidal intentions. The autopsy excluded signs of struggle and sexual intercourse as well as any type of injury or physical illness. Chemical analyses on the peripheral blood excluded acute drugs and/or alcohol intoxication. A differential diagnosis of the manner of death was performed, including scenarios of accidental autoerotic asphyxiation, homicide during either sexual activity or ritualistic, elderly suicide. The collected data most strongly supported the hypothesis of a suicidal asphyxiation simulating homicide to devolve a life insurance to the victim's sons because of economic difficulties.
该案例涉及一起不同寻常的自杀性塑料袋窒息事件。一名老年白人男性被发现死在其公寓内，部分衣物被脱去，仰卧在沙发上，头上套着一个用绳子系住的塑料袋，上肢和下肢被另外两根绳子紧紧捆绑，两根绳子的末端都打成了活结（自救装置）。警方调查发现公寓内没有色情物品，且间接证据表明没有精神疾病或自杀意图。尸检排除了挣扎和性交迹象以及任何类型的损伤或身体疾病。外周血的化学分析排除了急性药物和/或酒精中毒。对死亡方式进行了鉴别诊断，包括意外性自淫窒息、性行为或仪式过程中的杀人、老年人自杀等情况。收集到的数据最有力地支持了自杀性窒息伪装成杀人的假设，目的是由于经济困难将人寿保险转交给受害者的儿子。
