Mentioned in Episode 8: I Know Who Killed Me, the lair of a killer, which is full of all the things a good serial killer needs to do their work...and to be charged with said work by the police when they find the Evidence Dungeon.

Stuart was worried (pre-marriage) that his apartment could be taken as a Evidence Dungeon, if you looked at it with the wrong set of eyes.

It is theorized that Edgar Allen Poe discovered the first evidence dungeon, which is now a historical site in Baltimore, Maryland.
