DETROIT POLICE · INVESTIGATION BOARD

CASE FILES.

This is the working investigation board for the Ralph Palmer chronology. Each file opens into its own room, but the website deliberately stops short of retelling the book. The archive proves the story is real; the full investigation belongs in the book.

CASE FILE RULE: If a case card appears here, it opens. Where a full investigation is intentionally withheld or still being reconciled, the page says so plainly.
THE CRIMES

What was happening behind the files.

Before opening an individual investigation, understand the kind of crime investigators were dealing with. These rooms explain the era, methods and Detroit setting while deliberately withholding the searchable details of Palmer's specific cases.
