Agent Burger made sure that he’d gone through a rigorous process known as Bertillonage. Devised by the French criminologist Alphonse Bertillon in 1879, it was the first scientific method for identifying repeat criminals. Using a caliper and other special tools, Agent Burger, with the help of the Dallas police, took eleven of Morrison’s body measurements. Among them were the length of his left foot, the width and length of his head, and the diameter of his right ear.
