Hansen explained to investigators how he would abduct women at gunpoint, fly them out to his remote cabin in the woods, strip them and sometimes blindfold them before sending them off running into the woods. After giving them a head start, Hansen would then stalk and hunt them down like an animal in the kind of twisted human safari that you probably thought only existed in the dozen or so movies that have featured twisted human safaris.
And yes, in case you were wondering, he had in fact been doing it a while. Authorities had expected to charge Hansen with four murders, so it came as a surprise to them when he admitted to around 21 (but really, you can't be totally sure of the number when you're keeping track of something as mundane as how many people you've hunted down and shot). His hobby got him sentenced to 461 years plus life in the big house. And in case you thought we were joking about all the movies that get made about this type of thing, the movie about this case comes out next month, in which Hansen gets thwarted by Nicolas Cage.
