For six months, teacher Angela Csader walked into her kindergarten classroom with a secret. The 25-year-old Queen Creek woman was arrested in July on suspicion of having sex with a 16-year-old Gilbert boy - a boy who fathered her child. Yet officials at Anthem Elementary School and the Florence Unified School District said they knew nothing about it. She continued to teach students during a half-year span when she appeared multiple times before a Maricopa County court and was on supervised release with a curfew.
