(AP) — A central Florida woman helped save herself and her children by sending a message in an online pizza order that asked employees to call 911 because she was being held hostage. Employees recognized Treadway as a regular customer and called the sheriff's office. According to an arrest report, the couple had been arguing throughout the day, as Nickerson carried a knife. Nickerson was arrested and now faces multiple charges including aggravated assault with a weapon without intent to kill, battery and false imprisonment. Authorities credit Treadway's quick-thinking and the fast response by deputies for a peaceful conclusion.
