Code Unknown: 25 Cold Case Division Encounters with the Paranormal (Code Unknown Series)

Cold cases do not stay still. Investigators like to believe that a closed box in a records room is inert—that paper does not change, that photographs do not move, that a sealed evidence bag holds only what was placed inside it years ago. This collection exists because that belief, however comforting, does not always hold.

Across twenty-five departments, in twenty-five American cities, officers, technicians, archivists, and analysts encountered something that procedure has no adequate box for: evidence that changed after it was already filed.

Not lost. Not mishandled. Changed.
