Interesting Thought
This talks about how DB Cooper committed the crime 50 years ago. It occurred to me. He didn't kill anyone, so the statutes of limitation have probably expired. If he were still alive, he could walk into any police station in the world and say, "Here I am" and they couldn't lay a finger on him.
FYI: Personally, I don't think he survived the jump which is why some of the cash has shown up in the woods over the years.
