Hi Scott,
This bit about disappeared and unknown people reminded me of Phillip K Dick’s book, Flow my tears, the policeman said. In this story, the protagonist, a well-known TV personality, wakes up one day with no identity. No one knows who he is. This is a big problem as he also lives in a police-state future USA and having no identity is a criminal act.
Just a bit of idea mining. Seems a little like lateral thinking to me.
