Single gunshots can cause multiple entrance wounds, almost always after the bullets have first struck intermediate targets. The phenomenon is commonly seen with relatively high-velocity jacketed ammunition and consequent separation of jacket and core. We herein present two representative cases with a discussion of the mechanism of injury.
Sudden death caused by foreign-body perforation of the esophagus is distinctly uncommon. We report the death of an elderly patient in a nursing home who exsanguinated after she swallowed a chicken bone that perforated her esophagus and right common carotid artery.
A case of accidental death resulting from a dropped tear gas pen gun is described. Tear gas pen guns can be easily altered to fire regular ammunition and can accommodate a variety of ammunition. Other similar pocket-sized weapons are mentioned.
