The 30-year-old mom who posed as her own 13-year-old daughter and spent the day at her school says she pulled the stunt to make a point about school security. Wearing a mask, hoodie, and glasses, 4-foot-11-inch Casey Garcia posted videos from inside the school. She revealed that it was a teacher who discovered her true identity. Garcia was arrested for criminal trespassing. She says the only reason she did it was to prove that school security needs improvement.
