⚖️ Behavioral Science & Ethics🟢 BasicAsphyxial Deaths

Traumatic and Autoerotic Asphyxia

Forms of asphyxia in which breathing is prevented by chest compression or by risky solitary behaviour, rather than by a ligature pulled by another.

Key points

Traumatic asphyxia happens when the chest is crushed, for example in a crowd or under a heavy weight, so that breathing cannot take place.
It causes a striking blue-purple congestion of the head and neck with pinpoint bleeding spots in the skin and the eyes.
Autoerotic asphyxia is accidental death during solitary breath-limiting behaviour done for stimulation, usually in private.
The scene often shows protective padding under a ligature and a means of escape that failed, pointing to accident rather than suicide.
Careful study of the scene and the body separates these accidental deaths from suicide or homicide.

Memory trick

Traumatic asphyxia is a chest crush giving blue-purple head and neck congestion with pinpoint bleeds; autoerotic asphyxia is accidental solitary breath-limiting (padding and a failed escape point to accident).
