I have no idea, but since when is "go missing" not a common thing? Why did that have to be explained? Do the Americans say "Mrs. Johnson's daughter went to a party, and she got misplaced, they haven't seen her since!" as opposed to "Mrs. Johnson's daughter went to a party, and she went missing, they haven't seen her since!"

Or what?
