When the words “Code red lockdown” crackled over her radio, Florida librarian Diana Haneski’s mind began to race.
She and her colleagues at the Marjory Stoneman Douglas High School had only recently had active-shooter response training, and were told to expect a drill.
But straight away, before a single gunshot had even echoed across the campus, she knew the threat was real.
In those moments, thoughts of a friend and fellow librarian came into Haneski’s head – Yvonne Cech of Sandy Hook Elementary. The 58-year-old has been credited with saving the lives of 22 people, including 18 students, by locking them inside a small supply closet during the horrific 2012 massacre.
The 20-year-old gunman took 28 lives that December morning, including his own. And had it not been for the quick thinking of Cech, it would likely have been more.
“She was there that day in Sandy Hook,” Haneski told Reuters, “and because of her I knew what to do.”
