Homicidio por combinación de métodos de asfixia / Homicide by combination of methods of asphyxiation

Introducción el homicidio por combinación de métodos de asfixia se observa mayoritariamente en las personas de edad avanzada o con algún impedimento físico capaz de contrarrestar la agresión. Material y métodos se realizó un estudio observacional retrospectivo sobre 634 autopsias, cinco cumplían las características de homicidios por combinación de métodos de asfixia. Resultados dos hombres y 3 mujeres, con edad promedio de 69 años, con estudios toxicológicos negativos, víctimas de un solo agresor, presentaron lesiones cutáneas periorificiales (bucales y nasales), hemorragias musculares en el tórax, fracturas costales, lesiones contusas en la cabeza, interpretadas como de sometimiento. Discusión en la combinación de métodos de asfixia, los hallazgos que deben ser vistos en conjunto son: traumatismos craneoencefálicos para someter a la víctima, lesiones cutáneas en el cuello, la cara, la cara interna de los labios, fracturas costales y lesiones por contrapresión en la espalda, los glúteos o los codos. Contextualizados en conjunto pueden explicar la dinámica de esta modalidad homicida. (AU)

Introduction Homicide by combination of suffocation methods is observed mainly in elderly people or with some physical impediment capable of counteracting the aggression. Material and methods A retrospective observational study was carried out on 634 autopsies. Five met the characteristics of homicides by combination of asphyxiation methods. Results Two men and three women, average age 69 years, with negative toxicological studies, victims of a single aggressor, presented peri orificial skin lesions (mouth and nose), muscle hemorrhages in the thorax, rib fractures, blunt injuries to the head interpreted as like submission. Discussion In the combination of asphyxia methods the findings that must be seen together: Head injuries to subdue the victim, skin lesions on the neck, face, inner face of the lips, rib fractures, and counter-pressure injuries to the back, buttocks, or elbows. Contextualized together, can explain the dynamics of this homicidal modality. (AU)

Multiple forms of suffocation used in double murder.

This paper presents a case of double murder in which different mechanisms of suffocation, involving smothering, burking, and manual strangulation, were used. The victims are usually elderly people with disabilities and social isolation. The cases described here involve two women who were disabled and were murdered through blockage of the airway. Even though similar suffocating mechanisms were used in the murders, the autopsy findings differed between the two cases. This difference between the two can be explained by a preexisting medical condition that the younger victim had, which was quadriplegia resulting from cerebral hemorrhage, which limited herself-defense ability.

Homicide by hanging: A case report and its forensic-medical aspects.

We report a rare case of homicide by hanging. The postmortem examination resulted in a verdict of death by suicidal hanging and the Public Prosecutor's Office released the body for burial. After intervention by the relatives police investigations were resumed. Based on evidence impossible to reconcile with the results of the postmortem examination and requiring further clarification, an autopsy was ordered. The results of the postmortem could not be brought in line with a suicidal hanging and were further substantiated by DNA analysis. The scenario put forward by the defense claiming a secondary transfer of trace evidence onto the ligature and the victim's clothes was excluded because of the distribution pattern and the trace evidence ratio. The defendant was sentenced to 20 years of prison for homicide. The verdict was confirmed by the Supreme Court and commuted to 18 years.
