Tentative injuries to exposed skin in a homicide case.

A 28-year-old man stabbed both his wife and his 3-year-old son to death, before unsuccessfully attempting to commit suicide. The incident occurred against a background of marital conflict. The child's body exhibited six tentative wounds to the skin in the area of the heart, with no corresponding defects in the overlying clothing, a pattern normally seen only in suicide. Their presence can be explained by the fact that this can be considered an extended suicide, the father's motivation for the killing being comparable to that for true suicide. However, wounds of this nature can be produced in such cases only if the victim is severely limited in his ability to defend himself, here due to the superior physical strength of the father.
