Beltrame B, Baig S, Verzeletti A. Forensic remarks regarding 35 cases of complex suicides and 4 cases of complicated suicides investigated at the Institute of Legal Medicine of Brescia during the period 1983-2022. Leg Med (Tokyo) 2023; 65:102324. [PMID: 37738750 DOI: 10.1016/j.legalmed.2023.102324] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 08/21/2023] [Accepted: 09/14/2023] [Indexed: 09/24/2023]
Abstract
The role of the forensic pathologist is central to both identifying the cause and determining the manner of death. Distinguishing a suicide from a homicide or accidental event is essential to define whether third parties are involved in death. Suicides are most frequently performed using a single method; therefore, they can be defined as simple. The term "complex suicide" refers to a form of suicide in which two or more methods are applied by the victim, simultaneously or in chronological succession, to achieve the death. The different methods may have been planned in advance to prevent failure of the first method or may occur because the first method was not effective or was too painful, so the victim quickly seeks another way to complete the suicide. "Complicated suicides", on the other hand, are characterised by an unintentional secondary trauma following the suicidal act. This study analyses 35 complex suicides and 4 complicated suicides investigated at the Institute of Forensic Medicine in Brescia (Italy) during the period 1983-2022. Some data about the cases are discussed. This study aims to demonstrate how multiple lesions on the victim's body are not in themselves indicative of the intervention of third parties in their production, but complex and complicated suicides must always be considered.

Leg Med (Tokyo) 2023; 61:102187.

Abstract
Complex suicides are rare events pursued by the victims by means of two or more different fatal methods and can be further classified in planned or unplanned depending on the simultaneous or sequential application of the methods, respectively. The multiplicity of the injuries detected can frequently lead to misinterpretations, thus making a multidisciplinary approach of utmost importance. Here an unusual unplanned complex suicide was described discussing the post-mortem data leading to the forensic diagnosis; moreover, a focus on the depression cause was reported. The case regarded a 48-year-old man with a recent diagnosis of depression who self-stabbed his neck and, subsequentially, fallen from height. Data obtained from autopsy, histology, radiology and toxicology were described, highlighting the main findings for achieving the differential diagnosis between suicide and homicide. Moreover, microscopic findings compatible with an unrecognized thyroiditis led to consider the thyroid dysfunction as a possible substrate of depression, suggesting it potential effect on suicidal behaviour.

Abstract
In complex suicides, more than one suicide method is applied at the same time or one after the other. The most common complex suicide includes the ingestion of drugs combined with drowning. A case of acute intoxication by Bisoprolol and drowning is reported. The dead body of a 40-year-old woman was discovered on a river side, soon after her husband found a suicide note at home. In the woman’s vehicle four empty boxes of Bisoprolol, a widely used beta blocker, were also found. Main autopsy findings were consistent with drowning and represented by plume of froth at the mouth and nostrils with frothy fluid also in the airways, water into the stomach, and a remarkable pulmonary edema as a result of fluid aspiration. Toxicological analyses were performed on peripheral blood, urine and gastric content samples using liquid and gas chromatography, coupled with mass spectrometry. Toxicological results were negative for ethanol and other common drugs of abuse. High levels of bisoprolol were found in blood (7.54 mg/L), far exceeding the therapeutic range, in the urine (1.14 mg/L), and gastric content (13.12 mg/L). Bisoprolol intoxication was assessed as a relevant contributing condition to the immediate cause of death represented by drowning. Although Bisoprolol would certainly have a heart-depressing effect, it is not possible to determine if the victim fell unconscious or if she simply collapsed into the water with a secondary drowning.

Abstract
Abstract
Background
The use of more than one potentially lethal method together and sequentially to complete suicide is called “complex suicide.” Complex suicides are divided into two groups: planned and unplanned. This study aimed to discuss with literature 21 complex suicide cases identified after a 2-year retrospective study.
Results
This study included 21 complex suicide cases. Eleven were classified as planned complex suicides, and 10 were labeled as unplanned complex suicides. The average age of all cases was 42.5 ± 17.7 (min: 19, max: 76) years. Suicide notes were present in six (28.5%) cases. Fifteen victims (71.4%) suffered from psychiatric diseases. Twelve victims ingested a toxic dose of medication, nine cases jumped from a height, eight cases used stabbing, six cases used hanging, two cases ingested a corrosive substance, two cases drowned, two cases inhaled a toxic gas, one case ingested cyanide, one case ingested insecticide, and one case used suffocation with a plastic bag. In two cases, three methods of suicide were used together. In the current study, “corrosive substance intake + cyanide intoxication” and “corrosive substance intake + jumping from a height” were defined for the first time and have not been previously described in the literature.
Conclusions
Complex suicides are highly likely to be potentially mistaken for murder. The cause of death in these cases can be determined with a comprehensive autopsy along with a detailed examination of the scene, statements of relatives, and eyewitnesses.

Abstract
ABSTRACT Fatal sodium nitrite poisonings are unusual in the forensic setting. Suicide by poisoning includes drug overdose, the inhalation of toxic gasses, and poisoning from pesticides and chemical substances. Sodium nitrite is an inorganic compound usually seen as a crystalline powder that is very water soluble. Sodium nitrite is used mostly in the food industry (as a preservative) and in medical field (as an antidote to cyanide poisoning), and if ingested in large enough amounts, it can be fatal.The ingestion of sodium nitrite can cause severe methemoglobinemia, which is a metabolic disorder characterized by an inability of hemoglobin (which gets oxidized into methemoglobin) to bind (and therefore carry) oxygen. Severe cases of this condition, if not treated, can be fatal.We describe a case of fatal self-poisoning with sodium nitrite; in particular, the article focuses on the autoptic and toxicological investigations that enabled the correct diagnosis to be established.

Abstract
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.

Abstract
The authors present the first case, to the best of our knowledge, of a preplanned suicide by self-waterboarding. Waterboarding (WB) is a military method of torture in which water is poured into the nostrils and the mouth of a victim, to evoke the sensation of asphyxiation by drowning. The victim was a 22-year-old male student, who was found dead and naked in the bathtub. His head was covered by a soaked canvas bag, and his hands were tied with two nylon ropes and a padlock. The water jet of the showerhead was specifically directed at the victim’s head, so that the canvas bag could be soaked with water. The cause of death was defined as the combination of asphyxiation by drowning with the direct suffocation provoked by the soaked canvas bag in the context of the waterboarding practice. Finally, the authors discuss the differential diagnosis regarding the modality (suicide versus homicide) through which this case of waterboarding was performed. The case is intended to be used as source data for similar forensic cases, where a multidisciplinary approach is advisable in such complex cases.

Abstract
We describe an unusual case of a burnt body with a shotgun head injury found on a "bed" made of wooden boards on a pile of banknotes, resembling an altar. The body belonged to a 64-year-old man, of Greek nationality, with cancer who set his house (including the room in which he was found) and vehicle on fire before shooting himself, planning this way his postmortem burning. The combination of fire with the use of an "altar" and the destruction of body and possessions creates a unique death scene that implies a suicide with a ritual character.

Abstract
Complex suicides involve more than one suicide method. According to the intention of the victim, they are classified as 'planned' when the use of more than one suicide technique has been previously devised by the victim and 'unplanned' when the first method turns out to be too painful or insufficient to cause death, and the individual then resorts to other means of suicide. Complicated suicide, on the other hand, is a term that was introduced by Töro and Pollak, in which a failed act of suicide is followed by traumatisation, which has a fatal outcome. This type of death must be distinguished from complex suicides. From a sample of 1160 fatalities (837 males) between 1993 and 2017, we identified 20 (1.72%) cases of complex suicide and three (0.26%) cases of complicated suicide. We considered age, sex, psychiatric history, previous suicide attempts, suicide methods and eventual secondary traumatisation. We also compared planned and unplanned complex suicides. The results show a higher number of planned complex suicides (16 vs. 4), a prevalence of males (n = 17) and adults (median age = 48 years, range 21-74 range). Plastic bag suffocation and gas inhalation (n = 8) were the most commonly used methods. Firearms (n = 4) were used exclusively by males in planned complex suicides. Wrist and forearm cuts (n = 5) were found in four unplanned and one planned complex suicides, and all of the cases with known previous suicidal attempts (n = 3) involved planned complex suicides. Complicated suicides concerned three male victims in two failed attempts of hanging and an unforeseen carbon monoxide intoxication following a non-fatal gunshot to the mouth, confirming the rarity of these fatalities.

Abstract
Complex suicides are highly uncommon suicides in which multiple detrimental methods are used simultaneously or in chronological succession. We retrospectively analyzed through our database the 25512 autopsy reports registered at the Bureau of Legal Medicine of Milan in the last 27 years from 1993 until 2019, where 4498 suicides were documented. We assessed 53 cases of complex suicides and only one case of complicated suicide: for all of them we analyzed both data collected during the on-site investigation and the autopsy. In our case series, we identified a total number of 113 methods chosen and variably combined by the victims, which were classified into 17 categories. On the whole the most frequent association of suicide methods resulted in the combination of the plastic bag suffocation with inert gas inhalation (13 out of 53 complex suicides; 24.5%). We also analyzed our cases of simple suicides (1993-2019), to compare them with the complex suicides. In this study, we present a complete analysis regarding our cases of complex suicides, discussing the challenges and the interpretative issues which a forensic pathologist might deal with. A thorough on-site judicial inspection and a careful autopsy examination are crucial in such cases. Moreover, the clinical history of the victims and laboratory findings are supplemental elements to be necessarily considered to establish the actual manner of death and avoid any misinterpretations.

Detection of helium in a fire victim: A case report. Forensic Sci Int 2020; 318:110613.

Abstract
We report here detection of helium in specimens derived from a burn autopsy case. A male was found in a burnt bedroom. Part of a heat-denatured plastic bag, sealing tape, and flexible tubing remained on his head and neck. In addition, five helium tanks were found near him. His history in conjunction with the discovery conditions suggested a suicide attempt by inhalation of helium. The body had extensive first to fourth degree burns caused by heat. A small amount of soot was deposited in the respiratory tract. Except for the thermal burns, no other injuries were found. Toxicologically, the blood carboxyhemoglobin saturation levels were less than 6%, while combustion-derived volatile hydrocarbons such as benzene or toluene were detected in the blood. In addition, tracheal gas, gastric gas, headspace gas of lung tissue, brain, and heart blood were collected during autopsy for detection of helium. Analysis was performed using headspace gas chromatography with a thermal conductivity detector. Helium was detected in all of the samples tested. Etizolam at a low limit of therapeutic concentration or less was detected in the blood. Neither ethanol nor other drugs of abuse were detected in his blood or urine. Autopsy findings and experiments suggest that the victim inhaled helium and was still alive when a fire broke out. The cause of his death was diagnosed as death from fire and flames. The present result suggests that helium may remain in a burned body and that investigation of helium in cases of fire-related deaths is informative for determination of the cause of death or confirmation of the ante mortem involvement of helium.

Abstract
The body of a 53-year-old man was found in a burning car. The ignition key was in start position and the accelerator pedal was held down by his right foot. Autopsy revealed a gunshot entrance wound in the hard palate, a bullet track through the anterior cranial fossa and a projectile lodged in the left frontal lobe. The brain stem was free of lesions and any signs of secondary brain injury, such as brain oedema and intracranial haemorrhage, were not significant. Soot deposits and thermal injury to the mucosa were observed in the airways below the glottis and carboxyhaemoglobin (COHb) saturation was 40%. A single bullet case and a handgun were recovered next to the driver's seat. Fire investigators identified the motor as the beginning of the burning: therefore, the conclusion was that the car had caught fire due to overheating of the engine. Differential diagnosis between complex and complicated suicide was essential. The cause of death was identified as carbon monoxide intoxication, and the injuries to the brain were not felt to be immediately fatal. The case has been classified as a complicated suicide. There are no other published cases of a complicated suicide involving exposure to fire or the use of firearms.
