Where is the next one like him? Prolly driving a rig from state to state, with a hostage he would torture and slowly kill; Or making Candy (the candy man) in a Texas town, "the rope", another strangler from gainsville.
There are all kinds of sicko's running around, and from time to time they catch one. I used to read Anne Rule's paperbacks, who wrote about many of them.
The worst of it is it can be someone you have known for a long time and completely trust, or it can be a relative stranger, a new person in town that seems harmless. You just never know.
Sounds like the b-movie, 'Suspect Zero'. ...his property had 100s of graves when finally caught.
