据美国联邦调查局报道，2023年5月，当局就涉嫌威胁实施校园枪击事件采访了当时13岁的嫌疑人。
美国联邦调查局表示，他们收到了匿名举报，称有人在网上威胁要制造校园枪击事件，网上威胁包含枪支照片。
根据ABC新闻获得的警方报告，男孩的父亲告诉当局，他在房子里有猎枪，他说，“柯尔特在监督下可以使用它们，但不能不受限制地使用它们”。
据报道，一名官员写道，当这名13岁的男孩接受采访时，他“向我保证，他从未威胁要射杀任何一所学校”。
网上威胁包括一个用俄语写的用户简介，调查人员当时表示，俄语字母的翻译拼出了兰扎的名字，指的是2012年桑迪胡克小学大规模枪击案的肇事者亚当·兰扎。
“我无法证实我从美国联邦调查局得到的采取进一步行动的提示，”一名官员在报告中写道。“目前，由于美国联邦调查局收到的信息不一致，关于柯尔特或[他的父亲]是发出威胁的不和谐账户背后的用户的指控无法得到证实。”
“当时，没有逮捕或在地方、州或联邦层面采取任何额外执法行动的可能原因，”美国联邦调查局周三表示。
警长办公室表示，它“提醒当地学校继续监控这个问题。”
Discord在一份声明中表示，该账户创建于2023年4月2日，并于2023年5月21日被该平台删除，“因为违反了我们反对极端主义的政策。”
“当时，Discord的安全团队立即对执法部门做出了回应，提供了所有要求的信息以协助他们的调查，并迅速采取行动将用户从平台上移除，”Discord说。“根据我们自那以后进行的调查，我们没有迹象表明嫌疑人利用不和来讨论或计划这场可怕的袭击。”
Georgia school shooting latest: 14-year-old suspect's father arrested, charged with murder
The father of the 14-year-old student accused ofopening fireat Apalachee High School in Winder, Georgia, has been arrested and charged with murder in connection with the deadly shooting, the Georgia Bureau of Investigation announced Thursday.
Colin Gray, 54, was charged with four counts of involuntary manslaughter, two counts of second-degree murder and eight counts of cruelty to children, the GBI said.
At a news conference on Thursday evening, Chris Hosey, director of the GBI said that the father was arrested for "knowingly allowing his son, Colt, to possess a weapon."
His son has also been charged with four counts of felony murder, with additional charges expected, the GBI said.
Two teachers and two studentswere killed in Wednesday morning's shooting: math teacher and football coach Richard Aspinwall, 39; math teacher Cristina Irimie, 53; and students Mason Schermerhorn, 14, and Christian Angulo, 14, officials said.
Eight students and one teacher were injured, officials said. All of the injured victims are expected to recover, Barrow County Sheriff Jud Smith said.
At Thursday night's briefing, while addressing the condition of the nine injured, an official said he was "very happy to say they will make full recovery." Some of them are still in the hospital, while others have been released.
The suspect, Colt Gray, surrendered at the scene to the school resource officers, the GBI said. He was taken into custody at 10:30 a.m. ET, seven minutes after the initial service call went out, according to the Barrow County Sheriff's Office, which employs the school resource officers.
Colt Gray will be tried as an adult, the GBI said.
He is being held at the Gainesville Regional Youth Detention Center and will appear in court virtually on Friday morning, authorities said.
An AR-platform-style weapon was used in the shooting, according to GBI Director Chris Hosey.
Officials said they did not yet have answers for how Colt Gray was allegedly able to obtain the gun and get it into the school. Colt Gray was interviewed by investigators and the GBI, but Smith did not disclose further details.
Teachers at the high school had IDs that alert law enforcement during an active incident -- a new safety system that was implemented just one week ago, the sheriff said.
A motive has not yet been determined and it is unknown if the victims were targeted, investigators said.
The suspect had an apparent affinity for mass shooters, multiple sources familiar with the investigation told ABC News. Investigators are scouring concerning social media posts from accounts associated with Colt Gray that mention prior mass shootings and those who carried them out, the sources said.
The GBI said in a statement Thursday, "This is day 2 of a very complex investigation& the integrity of the case is paramount. We ask for the public’s patience as we work to ensure a successful prosecution& justice for the victims."
The autopsies will be performed on Thursday, the GBI said.
In May 2023, authorities interviewed the suspect, who was then 13, about alleged threats to commit a school shooting, according to the FBI.
The FBI said it received anonymous tips about online threats to commit a school shooting and the online threats contained photos of guns.
The boy's dad told authorities he had hunting rifles in the house, saying, "Colt is allowed to use them when supervised but does not have unfettered access to them," according to the police report obtained by ABC News.
When the 13-year-old was interviewed, he "assured me that he never made any threats to shoot up any school," an officer wrote, according to the report.
The online threat included a user profile written in Russian, and investigators said at the time that the translation of the Russian letters spelled out the name Lanza, referring to Adam Lanza, who committed the Sandy Hook Elementary School mass shooting in 2012.
"I could not substantiate the tip I received from the FBI to take further action," an officer wrote in his report. "At this time, due to the inconsistent nature of the information received by the FBI, the allegation that Colt or [his father] is the user behind the Discord account that made the threat cannot be substantiated."
"At that time, there was no probable cause for arrest or to take any additional law enforcement action on the local, state, or federal levels," the FBI said on Wednesday.
The sheriff's office said it "alerted local schools for continued monitoring of the subject."
Discord said in a statement that the account was created on April 2, 2023, and removed by the platform on May 21, 2023, "for violating our policy against extremism."
"At that time, Discord’s Safety team immediately responded to law enforcement, provided all requested information to aid in their investigation, and acted swiftly to remove the user from the platform," Discord said. "Based on our ongoing investigation since then, we have no indication that the suspect used Discord to discuss or plan this horrific attack."
