An unusual case of "dyadic-death" with a single gunshot

The terms "dyadic death'' or "murder-suicide'' refer to an incident where an individual commits homicide and then takes his or her own life. These events are generally committed by men within the family network, using firearms or sharp force instruments, and make up a relatively small proportion of homicides overall. Herein, we present the application of post-mortem multislice computed tomography (CT) and micro-CT analysis to an unusual case of dyadic death, where a 38-year-old man fired a single gunshot to his own right temple, killing himself and his 50-year-old wife, lying on the bed beside him.The integration of radiological, autoptic and histological data allowed us to reconstruct the trajectory of the gunshot, the most probable dynamics of the event, and to classify the incident as a "suicide-homicide'', because the female victim died a few minutes later than her husband and murderer.
