A woman in Florida who was being held hostage by her boyfriend was able to save herself from harm when she ordered an online pizza with a secret message saying she was being held hostage. While Cheryl Treadway was being held at knifepoint by her angry boyfriend, she convinced him to give back her phone so she could order a pizza using a Pizza Hut smartphone app. In the order's "Comments" section, she wrote "Please help. Get 911 to me!" The Pizza Hut worker who saw the message in the order then called the police, who went to the hostage's house and arrested her boyfriend. “We've never seen that before,” said Candy Hamilton, the Pizza Hut manager. "I've been here 28 years and I've never, ever seen anything like that come through."
