Death by bull-edger. An unusual homicide using a woodworking implement

Impulsive killers often use whatever instrument is close at hand in the perpetration of their deed. We describe a homicidal death, first thought to be accidental, in a rural sawmill where the assailant manipulated a large board of wood into a machine known as a bull-edger (which cuts logs into rough boards) in such a fashion as to cause the death of his work partner. The physics of the events at the scene as well as the subsequent investigation are discussed.
