Officer McQueen

Officer Katz was one of three kidnapping victims by the Mad Hatter in one of his attempts to break Batman during the events of Halloween.

History
During the events of Scarecrow's attack on Gotham City on Halloween night, McQueen had been on patrol when her siren started to malfunction, forcing her to pull over. Not long after she pulled over, however, she was knocked out by the Mad Hatter (who had been responsible for modifying her and two other police officers' squad car's sirens to implement a hypnotic tune), and then locked up inside the trunk of her own car while wearing a mask mirroring the Queen of Hearts/Red Queen from Alice's Adventures in Wonderland, with the trunk also being rigged with explosives to ensure Batman couldn't rescue her easily. Mad Hatter then had her car placed at the island lighthouse near Chinatown, also defacing her car with statements from the book. Batman ultimately managed to disarm the explosives and rescue McQueen, who was confused and frightened about the ordeal and wondering what happened to her before Batman reassured her that she was safe. She was then brought back to the GCPD, where she was sitting in the corner with Officer Katz due to the trauma of what they had to endure. She also expressed disgust about Jervis Tetch and expressing that she can't even look at him after what he did to her.
