Finger nail abrasions in manual strangulation (throttling).

ABSTRACT

Autopsy surgeons, often observed that the nail abrasions produced over the neck of victims in manual strangulation are almost straight and do not resemble the shape of nails, which are semi-circular/cresentic. A study is undertaken to know the reason for the same. During the study it is observed that the skin gets stretched while the assailant is applying pressure and only then nails produce indentations. Once the pressure is removed the stretched skin reverts back to its original position. Thus the semicircular indentations caused over the stretched skin appear straight after the skin regains its original position.
