DEKALB COUNTY, Ga. (WSB-TV) -- Police say a man who walked into a DeKalb County elementary school brought nearly 500 rounds of ammunition.
Michael Brandon Hill waived a first court appearance on Wednesday but could be in a DeKalb County courtroom on Thursday, investigators said in a news conference.
Police said Hill brought an AK-47 style assault rifle to McNair Discovery Learning Academy on Tuesday afternoon.
Police said Hill never entered the classrooms of the school and remained in the office during the entire incident, except when he emerged briefly to exchange gunfire with police.
“He came there to do one of two things: Do harm to the children or any first responders,” DeKalb County Police Chief Cedric Alexander said. “Fortunately this came to an end quietly, without incident.”
WSB listened to 911 tapes made to dispatchers during the incident.
“He’s going to start shooting, including the police,” a woman said on the phone.
Investigators said Hill fired one shot inside the school, a single round into the floor of the office. No one was injured.
One of the women held captive in the school office, Antoinette Tuff, called WSB to report that there was a shooter in the school. She told an assignment desk editor that the gunman asked her to call the media and police.
WSB spoke exclusively to Tuff who said she spoke for nearly an hour to Hill about her life and his own all the while saving the lives of many others.
"The clips that go into the gun...he sat there right in front of me in the office and began to load them with bullets," Tuff told Moore.
"I just started praying for him," Tuff said. "I just started talking to him and allowing him to know some of the stories and let him know what was going on with me and that it would be OK. And then let him know that he could just give himself up."
Students and staff at McNair elementary spent the day at McNair High School. The elementary school remained a closed crime scene.
Detectives passed out a picture that Hill took of himself holding a gun in front of a bathroom mirror.
The Bureau of Alcohol, Tobacco and Firearms is testing the weapon used at the school. Officials said Hill obtained the gun from the home of an acquaintance but they had not found the owner.
Hill is charged with aggravated assault on a police officer, terroristic threats and possession of a firearm by a convicted felon.
