Sarah Youngman

Officer Sarah Youngman is a character who posthumously appears in Scrutinized. She was the older cousin of Luna Youngman, though they were so close their relationship was more akin to sisters. Sarah was a morally upstanding police officer that was tragically murdered by the Blueblood Killer, motivating Luna to hunt him down.

There's actually a photo of her in the room where you have to turn on the fuse box.
