USB key in Jimmy Hoffas pocket
About the last idea, I had to look up that name:
> James Riddle Hoffa (born February 14, 1913; disappeared July 30, 1975; presumed dead July 30, 1982) was an American labor union leader who served as the president of the International Brotherhood of Teamsters (IBT) from 1957 until 1971.
Do I read it correctly if I understand "Jimmy Hoffas pocket" to be one implementation example of "any disappeared person's pocket"? Or is the specific person, their role, or their era relevant?
There are only a few "famous mysteries" that became such widespread memes in American culture. The ones I can think of are:
1. What happened to Jimmy Hoffa (who killed him?). "The Irishman" on Netflix is a Scorsese adaptation of a "nonfiction" book that documents an old Mafia hitman claiming to have killed Hoffa. (The book is nonfiction, the guy's claims are somewhat contested.)
2. What happened to Amelia Earhart? (Early female aviator who disappeared attempting to fly around the world).
3. What happened to and who was DB Cooper? (A man hijacked an airplane, traded some hostages for a duffle bag of cash at an airport when such a thing was possible, told the pilots to fly to Canada and then jumped out of the plane with a parachute and the duffle bag somewhere over the pacific northwest).
4. Who shot JFK?

First find Jimmy (embedded in concrete?). Then notice that there's no time element; Jimmy's USB key will be found when Jimmy's found, which might be tomorrow or it might be never. Then learn that he disappeared long before USB keys were invented.
I realize the suggestion was light-hearted!
