Detective Kimball’s plea comes just over a month after Sara Abusheikh, a Los Angeles fashion designer, wrote in a post on Medium about her experience with the detective after she was sexually assaulted by an acquaintance in 2014, and reported it to the authorities. Detective Kimball was assigned to her case, but she wrote that he never investigated, and instead said wildly inappropriate things to her.

Ms. Abusheikh wrote that Detective Kimball teased her about going back to her assailant and suggested she “let him make love to you gently.”

“His only interest in the details of my rape came in the form of perverse, sick questions, and he — most tellingly — suggested he come inside to get high,” she wrote.

She later filed a restraining order against her assailant, which led Detective Kimball to joke that she was paranoid, she wrote. When she reported his inappropriate behavior to his supervisor, word got back to Detective Kimball immediately, she added.

The next summer, after getting help from a rape treatment center, she met with the Los Angeles County district attorney’s office , which declined to prosecute the case, she wrote. A deputy district attorney told her Detective Kimball was “a fine detective” and insisted there was no evidence to back up her claim, she wrote.

“And the Special Victims Bureau? It only functioned to protect not one, but two, alleged rapists,” Ms. Abusheikh concluded in her essay.

The Los Angeles County district attorney’s office declined to comment on Ms. Abusheikh’s post.

Last year, Ms. Abusheikh shared screenshots of text messages she said were from Detective Kimball with The Daily Beast, as well as records of email exchanges with lawyers and patient advocates from the rape treatment center. She did not return calls or respond to messages seeking further comment.
