Chelsea Peretti played Gina Linetti on Brooklyn Nine-Nine for several seasons before she was abruptly written out of the show, leaving fans wondering, “Why did Gina leave Brooklyn 99?” Gina served as the 99th Precinct’s civilian administrator and was known for weird antics, sarcastic remarks, and disinterest in work. The announcement of Peretti’s departure was a shock, especially since it followed a tumultuous 2018 when Fox canceled Brooklyn Nine-Nine. Though NBC picked up the show, news of Peretti leaving soon followed.
