Arrest of Robert Hansen: Mysterious Aviation Maps

Sometimes it’s the little things. In the search of Hansen’s house, troopers found a plethora of objects. Stolen goods. Mementoes likely taken from his victims. And, of course, lots of weapons. Among those items were some smaller, almost innocuous things: Maps.


“Behind the headboard of the waterbed [Robert Hansen] shared with his wife, they found an aviation map. [An]other had been in the attic with the rest of the mementos. Up until [mid-January], Flothe had been going a mile a minute. He’d spent little time being reflective. The maps represented nothing more than documents Hansen used for hunting. Yet while examining the maps with Pat Doogan, he saw twenty-four X marks. Were these favorite hunting spots — or something else?

“The answer that suddenly dawned on him was almost too grotesque to believe. ‘Oh my God,’ Flothe said, a chill coming over him. ‘What has this man done?’ At that moment he realized that each X marked a body.”

  1. There was much more to this story that was never revealed to law enforcement though. I served almost nine years at Spring Creek Correctional Center with Robert Hansen.
