Cassandra "Casey" Johnston, from Bucks County, PA, went missing in Chinatown, Philadelphia on Saturday July 10th, 2021 at 5:51am. She was seen getting into her car, a silver Ford Focus hatchback, and leaving her friends apartment to come home in Feasterville, PA. She has a history of mental health issues, and hasn't had her medicine since Friday. She doesn't have any history of substance abuse or illicit drugs. We're hoping to erect a billboard in the Philadelphia area to bring widespread awareness to her missing status so that we can hopefully bring her home safe and sound.
