Within minutes of the Dalton shooting, students there took to social media, calling for restricting gun rights.
The teacher, Jesse Randall Davidson, earlier this week locked the door of his classroom and "fired a shot from a handgun through an exterior window of the classroom", Dalton police spokesman Bruce Frazier said during a news conference. Later when he asked if they scared her, the friends said it was worse than that, which he understood to mean that they killed her, the incident report said.
He is a social studies teacher employed at the school since 2004 and the announcer for the school football team, according to Dalton police.
Wednesday's incident wasn't his first unusual interaction with law enforcement in Dalton, a city of nearly 35,000 residents about 80 miles northwest of Atlanta.
Police have not released an explanation for Davidson's behavior.
Officers' first run-in with the teacher involved his coming to the police. "He really wanted the students to understand the concept", said 18-year-old senior Rowdy Zeisig.
Police aren't saying why a North Georgia teacher allegedly brought a handgun to school and fired it out a classroom window, but a police representative says apparently the teacher didn't intend to harm any students.
Oscars 2018: 'Moonlight' to Be Presented With Best Picture Award Again
The 2018 Academy Awards will be hosted by Jimmy Kimmel for the second year in a row and presented on March 4. Instead of saying the correct name of the victor ( Moonlight ), the card read: " Emma Stone , La La Land ".
"[Davidson] then said 'Don't come in here". He told his wife about it.
Police are investigating the circumstances and motive behind the incident. "I challenge you to disclose to me furnishing educators will make us safe", she tweeted to the NRA.
The latest report from the Dade County Sheriff's Office said Randal Davidson set his auto on fire in August of 2016 and was considered to be "unstable".
That was when Davidson approached police.
The attack led to calls from U.S. President Donald Trump for arming teachers as a way to stop school shootings. The report concludes that he was delusional. Detectives couldn't verify that any of it was true, and he was taken to the hospital since he'd expressed thoughts of hurting himself, police wrote in their report on that episode. They had lived in Chattanooga, about 30 miles northwest of Dalton. They'd filed for Chapter 7 bankruptcy in late 2015. He told a supervisor he wasn't feeling well and walked out. However, when she arrived, his colleagues could not find him.
Assistant Police Chief Cliff Cason said in a statement at the time that officers planned an increased presence at the city's schools in response to the note.
He was conscious but would not react or respond to officers and emergency medical services took him to a local hospital.
