The case
The base: men who fall apart. Dahmer kept evidence at home; caught when a victim escaped. Tier four: organized men with stable lives. Rader left DNA at his scenes; caught by a floppy disk. Tier three: men who chose victims nobody reported. Ridgway: nineteen years, ended by DNA.
The mechanism
Why are some killers harder to catch than others?
The pyramid sorts killers by how many ways there are to catch them. At the base are men who fall apart and are caught by their own behavior. Each step up removes one catching mechanism. At the top none are left. Only luck or a confession.
Tier two: the planner. Israel Keyes buried supplies years ahead and crossed state lines, caught the one time he broke his rules. The top: a stranger who leaves nothing that names him, then stops. The Zodiac case, still open.
The rule
Each step up, one catching mechanism disappears. At the top none are left. Only luck or a confession.
