See, we've been following this from Pearl's point of view so far, since that's the weirdest, but if you really want a scary story, you need to see it from Olga's. La Rue, whose real name was Alphonse Rocco, was her husband of 18 months. She'd left him the previous April. Then this past October, he kidnapped her at knifepoint and kept her in a cabin for two days -- then returned to the city, got a gun, and kept her in the cabin for five more. Later, staying with her parents, Olga was shot in the leg. She couldn't prove it, but she assumed Alphonse fired on her from outside.
Olga repeatedly went to the police, who didn't act on her reports. The very day before Pearl shot her, she visited the police again, who now agreed to send officers to guard her, yet none did. She survived the shooting. But by the next day, doctors had amputated her leg, six inches above the knee.
Police did now chase Alphonse down, and they caught him robbing farmers in the mountains. He fired on them, and they returned fire, killing him. Pearl went on trial, where the jury considered her a victim in all this and found her not guilty. Olga also tried to put the city on trial for failing to protect her, but while they said maybe they would have been at fault had Rocco shot her himself, there was no way they could have predicted what actually happened, so she got nothing. She and Pearl did end up friends, though. And Olga got a job ... selling jewelry.
