Postal worker in Chicago dies in apparent suicide in mail truck Tweet about the suicide from an account tracking police scanner activity (@ChicagoScanner) At 10:20 p.m. Monday, @Chicago_Scanner, a Twitter account that posts frequent updates of police radio activity, tweeted, “Female mail carrier hanged herself in the back of the mail truck.” The tweet was in response to a question from another user, who had posted images of emergency vehicles and a mail truck outside their apartment, asking, “Have you heard anything around Belmont/Elston? This is outside of my apartment right now. There’s police tape up too and at least 5-6 cop cars.”
