A single fatal penetrating chest wound caused by a dagger-shaped fragment of broken door glass.

A 19-year-old woman ran against a glass door, and, breaking it, was struck in the left anterior chest by a single dagger-like fragment of broken door glass. This fragment deeply penetrated her chest and wounded the anterior wall of the left ventricle of her heart. She rapidly died from loss of blood. The majority of single fatal penetrating chest wounds seen at postmortem examinations are caused by firearms and bladed weapons. While penetrating chest wounds occasionally result from fragments of glass, most severe and fatal wounds from glass result from one's falling into or through plate glass and sustaining wounds of the head, face, abdomen, or extremities. A single fatal wound from a dagger-shaped piece of glass is distinctly uncommon. To prevent such an accident from occurring, safety glass must be used in front doors of public institutions.
