RESUMEN

Reconstruction of a criminal offense is a crucial approach in forensics and criminalistics allowing for the verification of the location, the particular method used, or the use of a specific instrument. This report describes the case of a young man who was killed by an arrow shot from a crossbow. The autopsy revealed a penetration of the head and significant damage to the brain stem. Although the cause of death was evident from the outset, it was necessary to clarify whether or not the arrow was shot as necessary self-defense. Ballistic investigation of the seized weapon and reconstruction of the crime was absolutely essential to bring forth conclusive evidence to convict the perpetrators of the murder.

RESUMEN

Chop or slash wounds are produced by sharp-edged tools such as an axe, or a machete. This paper presents a case of a violent death of a 57 year-old-man. Autopsy revealed deformation of the right side of the head. A total of 23 slash, stab and cut wounds as well as contused lacerations were identified on the scalp as well as the face and the neck. In addition, superficial abrasions and bruises were identified on the skin. The immediate cause of death was due to extensive brain contusion following fragmentation of the neurocranium. The injuries resulting in the death of the victim were sustained during an assault on the head with an axe, which was used both as a slashing tool and a blunt instrument.

RESUMEN

Penile carcinoma is an uncommon but potentially mutilating disease with a heterogeneous etiology. We present a case in which a man died due to severe blood loss from an amputated penis. It was initially regarded as a violent death with an external cause. Autopsy found irregular defects with smooth edges in the external genital area and on both sides of the groin, with yellowish-gray callus-like structures and dried blood at the base of where the penis would have been located. Histological examination revealed the presence of squamous cell carcinoma with signs of keratinization. Subsequent investigation, along with information from the autopsy, revealed that the man suffered from penile carcinoma, thus death was attributed to exsanguination from an ulcerated femoral artery in a patient with penile carcinoma.

RESUMEN

Cardiac injury following blunt chest trauma is common in motor vehicle accidents due to a crush or blast injury. Severe cardiac trauma is associated with a very high mortality. If a cardiac injury develops several weeks after non-penetrating chest trauma, establishing a causal link between the traumatic event and the cardiac injury becomes complicated. This article reports a case of fatal delayed hemopericardium and hemothorax following a motor vehicle accident including blunt chest trauma 34 days prior to death. The cardiac injury was caused by displacement of a sharp irregular fragment of one of the decedents fractured ribs and the primary defect was sealed by blood clots. Subsequent bleeding occurred when the thrombus was displaced. Since the incidence of blunt high-energy chest injuries is relatively high, heart and large vessel injuries must be taken into account and a comprehensive examination needs to be done in order to prevent the delayed development of fatal complications.

RESUMEN

Animal inflicted fatal or near fatal injuries are well described in the forensic literature, with the most frequently described cases involving dogs, large cats and bears. To our knowledge, a deer inflicted fatality has not been described in the forensic literature previously. This article reports a case of a 64-year-old male, who was found lying in a pool of blood near an enclosure for stags and hinds at the end of October. There were mechanical defects on his jacket and trousers, which appeared to be torn or penetrated, as well as multiple lacerations and stab wounds in different parts of his body. The type and location of the injuries the man had sustained strongly suggested that another person had been involved in the incident that had led to his death. The cause of death was deemed as external exsanguination due to multiple stab wounds to large vessels. After evaluating all of the information regarding the circumstances around the death, the case was classified as a deer attack related fatality, and the manner of death was determined to be accidental. The man was most probably attacked by one of the deer while he was refilling the animal feeder. A substantial increase in the levels of selected hormones, especially testosterone, during the rutting season explains the increased levels of aggression shown by the deer that led to a fatal outcome for the decedent.

RESUMEN

A young adult black female, known to be a prostitute and suspected of smuggling narcotics, was found dead in her apartment in a state of early decomposition. Oval-shaped gray-white masses of exogenous origin protruded from the anus. The autopsy showed dilatation of the folds of the large intestine, which were almost completely filled with these oval-shaped gray-white masses of foreign material. The uterus was enlarged with multiple large leiomyomas. Toxicological tests of blood and the foreign material revealed no toxicologically relevant substances. Kaolin was detected in a sample of the foreign material from the large intestine. The immediate cause of death was intestinal obstruction due to the formation of a kaolin bezoar with simultaneous compression of the large intestine by the enlarged myomatous uterus. Subsequent revelation of a habit the deceased had brought from her native country led to the conclusion that this exotic custom was responsible for her death.

RESUMEN

Sharp force injuries are uncommon in routine forensic practice. While the majority of these cases are homicides or suicides, a significant minority of accidental deaths means that a careful investigation of the circumstances of the death is necessary. We present the case of a young man who presented with stab and cut injuries due to a duralumin rod embedded in his chest. Examination of the body revealed that death was due to penetration of the thoracic aorta by a duralumin rod. Careful investigation of the circumstances surrounding the death was able to confim a case of accidental death due to falling from a ladder onto tomato seedlings that were supported by duralumin rods.

RESUMEN

Fatalities due to gas intoxication are rare in routine forensic casework. The most common gas is carbon monoxide, with other gases (ammonia, methane, propane and butane, carbon dioxide, hydrogen sulfide) encountered only very rarely. In this report, we describe the accidental death of two maintenance workers who were found in the silage pit at a biogas plant. The autopsy revealed signs of asphyxia in both the deceased. Analysis of the gaseous mixtures in the tank using an infrared gas analyzer showed slightly elevated concentrations of carbon dioxide. Toxicological examination of the blood of both the deceased using gas chromatography with a flame ionization detector, spectrophotometry and liquid chromatography-mass spectrometry did not detect any toxicologically significant substance that would explain the sudden collapse. Both the autopsy and the toxicology analyses suggest CO2 intoxication as the most likely cause for the collapse of the two men, which then led to sudden asphyxia.

RESUMEN

In this study, we present two cases of sudden deaths of people with end-stage kidney with arteriovenous fistulas for long-term hemodialysis treatment. This procedure is associated with a number of known complications. While stenosis, thrombosis, and infection are well known, lethal hemorrhage from arteriovenous fistula is much less commonly encountered. Inspection of the bodies at the scene of the death by a medical examiner suggested that the deaths were due to exsanguination. Autopsies revealed visible defects on the front wall of the arteriovenous fistulas. Microscopic examination showed wall necrosis with infiltration of various inflammatory cells. Deaths were due to exsanguination from the ulcerated arteriovenous fistulas in patients with chronic renal failure. Further investigation revealed that complications in the area around the arteriovenous fistulas were known and were being treated until a sudden rupture of the vessels and hemorrhage from the arteriovenous fistulas resulted in the deaths.

RESUMEN

A 32-year-old pregnant woman in the 25th week of pregnancy underwent oral glucose tolerance screening at the diabetologist's. Later that day, she was found dead in her apartment possibly poisoned with Chlumsky disinfectant solution (solutio phenoli camphorata). An autopsy revealed chemical burns in the digestive system. The lungs and the brain showed signs of severe edema. The blood of the woman and fetus was analyzed using gas chromatography with mass spectrometry and revealed phenol, its metabolites (phenyl glucuronide and phenyl sulfate) and camphor. No ethanol was found in the blood samples. Both phenol and camphor are contained in Chlumsky disinfectant solution, which is used for disinfecting surgical equipment in healthcare facilities. Further investigation revealed that the deceased woman had been accidentally administered a disinfectant instead of a glucose solution by the nurse, which resulted in acute intoxication followed by the death of the pregnant woman and the fetus.
