Back in November of 2015, we brought you news that Michigan author Ross Richardson had a theory that hijacker D.B. Cooper was a grocer from Grayling, MI named Dick Lepsy. 

Recently, amateur scientists examined a clip-on tie, left behind on the flight D.B. Cooper parachuted from. According to, they found trace elements of exotic metals on the tie, which led them to believe that D.B. Cooper was an engineer who worked for a company that supplied metal or parts to the aerospace industry. Which would explain his familiarity with the Boeing 727 he hijacked.

Mr Richardson isn't convinced. He says, "There are no missing Boeing managers or engineers, so that kind of says that's not the person we're looking for."

Makes sense. Here's the story.
