Narrator: The story you are about to experience is true. None of the names have been changed because no one is innocent.
[voiceover] My name is Papa Swan and I’m a cop. An Internet cop. . .

and this is my partner, Fryler.

We got a notice from Groundspeak that someone was vandalizing geocaches. There were multiple reports of scattered cache contents and missing cache containers located in the same general area. We brought in a known low-life named Rick Dorsey for questioning.

Dorsey had a checkered past and was known to move frequently. A pretty boy with a bad attitude. Yeah, we knew just how to handle his type. We took him into the interrogation room for a little Q and A.

Papa Swan: Okay, punk, let’s start with the easy stuff. What’s your middle initial?
Dorsey: N
Fryler: What’s the N stand for:
Dorsey: Newton, as in Isaac Newton.
Papa Swan: Ha, more like Fig Newton in your case. What’s your educational background, Newton? Let me guess: high school dropout.

Dorsey: I spent two years at Peru State College in Nebraska studying aeronautical engineering. Ran out of money, so I left.
Papa Swan: Aeronautical engineering! Sounds like someone wanted to be the next Elon Musk, right rocket man?
Dorsey: Wrong. More like Igor Sikorsky. I really liked helicopters.
Papa Swan: Never heard of him. What do you do now, hot shot?
Dorsey: Meat inspector for the state. I make sure your steaks are clean and your burgers are pure. I’ll bet you cops like your meat well done.

Papa Swan: Enough of this chit chat. Where were you on the afternoon of the fifteenth? Ten geocaches were reported stolen that day.
Dorsey: I went to a movie called The Moth Man Returns. It was a matinee.
Papa Swan: Anyone see you there?
Dorsey: No one I know, but it took in 93 million over the weekend, so there were lots of people around.

Fryler: We have an eyewitness who can place you at the scene of one of those missing caches. I think you should play ball with us and maybe the judge will go easy on you.
Dorsey: Look, this kind of interrogation tactic may work in a backwater country like Lesotho or Kenya, but it won’t work here. You got jack squat on me and you know it.
Papa Swan: Watch it, you gutter-mouthed punk. Let’s move on the morning of the fourteenth. Six light pole caches were removed from the Walmart parking lot. An anonymous tipster reported seeing a car that looks a lot yours in the area. C’mon Dorsey, time to start singin’.
Dorsey: I can’t sing and I can’t dance. Besides, I was having a crown put in that morning. Can’t a guy see his dentist without his motives being questioned?

Fryler: How about we ask the questions around here. Now listen, Dorsey. We didn’t want to do this, but you give us no choice. We found a bottle of clear liquid in your car earlier today. Tell us why you bagged all those caches and maybe we’ll forget about this suspicious substance.
Dorsey: That’s an illegal search and you know it. Besides, it’s just insecticide. I hope no one got it on their skin.

Papa Swan: We’ll stay all night if we have to, Dorsey. Fryler, here, has a lie detector he’s dying to try out. How about we hook you up to it? If you tell the truth you walk.
Dorsey: That’s it! I’ve had enough of you guys. I want my lawyer. His name is Richard Nixon, like the president. This party is over and that is my final answer.
[Dorsey is led away]
Papa Swan: I hate it when they lawyer up. It takes all the fun out of interrogating. Regardless, we had him squirming in the hot seat and sure enough, Rick Dorsey spilled his guts.

Fryler: Yes he did. In fact, every answer he gave contains a clue.
Papa Swan: Then we can inform Groundspeak that our work is done here. Time to strike a pose.
