Demonstrative evidence developed at the autopsy.

A postmortem examination early during the investigative period of the murder of a young law enforcement officer on the edge of the Kansas Turnpike led to the development and application of a technique for the preservation of evidence by a visiting consultant. This resulted in the construction of a life-sized head which was used to demonstrate the entrance and exit sites of two bullets through the head and the site of the injury to the head from a pistol butt. This exhibit provided a dynamic demonstration of the relationship of the fatal weapon to the victim and contributed to the understanding of the paths of the bullets which passed through the victim's head into the ground. The technique is described.
