It's back to school this morning for students at a Decatur, Georgia elementary school that was the scene of gunfire on Tuesday.
New details have emerged about the suspected shooter, 20-year-old Michael Brandon Hill. According to prosecutors, Hill entered the Ronald McNair Discovery Learning Academy with an AK-47 type assault rifle and almost 500-rounds of ammunition.
Police also say he'd been previously convicted for making "terroristic threats."
But it’s the dramatic 911 call from the school clerk who convinced Hill to surrender that’s grabbing attention over the gunman.
“Alone in the office of an elementary school, book keeper Antoinette Tuff is face to face with a man armed with an assault rifle and close to 500 rounds of ammunition,” reports
CNN's Martin Savidge.
“It isn't just her life on the line, but the lives of hundreds of students and staff, as well as dozens of police officers now outside.”
Tuff is now being hailed as a hero for her holding her composure with the armed-Hill, all while she’s on the phone with a 911 dispatcher.
“To connect with the suspect she pours out her own personal story, of a marriage that suddenly ended and her own thoughts of suicide,” Savidge says.
"We all go through something in life....No, you don't want that. You going to be okay. I thought the same thing, you know, I tried to commit suicide after my husband left me But look at me now I'm still working and everything is okay,” Tuff says during the call.
Her sense of fearlessness and honesty moves even the police dispatcher.
"Maam, you're doing a great job,” the dispatcher tells her over the phone.
The police barge in moments later, after Tuff convinces the gunman to put down his weapon and lay down himself.
Only then does Tuff show her fear, saying “Let me tell you something baby, nothing so scary in my life!...Oh Jesus!"
