Marjory Stoneman Douglas High School math teacher Shanthi Viswanathan told her students to hide in a corner during the February 14 shooting.
She covered the classroom window with paper and locked the door.
According to a parent of one of her students, she refused to let even the SWAT team in, saying "Knock it down or open it with a key.
Her heroic actions saved her students' lives.
But a parent of one of Viswanathan's students told The Sun Sentinel that she did everything she could to make sure that her classroom remained safe.
She saved a lot of kids," Dawn Jarboe, whose son Brian was in her class, told The Sentinel.
When a SWAT team arrived to clear the room, she still wasn't taking any chances. »
