Shortly after his arrest earlier this week for killing two classmates and two teachers, suspected school shooting robber Colt Gray uttered three terrifying words to investigators: “I did it,” a local sheriff said.
A baby-faced 14-year-old boy charged with murder and scheduled to make his initial court appearance Friday confessed during questioning after the bloody massacre at Apalachee High School in Georgia, Barrow County Sheriff Jud Smith said. He told CNN.
Gray is accused of opening fire with an AR-15 rifle at a school in the Atlanta suburb of Winder on Wednesday morning, killing four people and wounding nine.
Authorities say the man was taken into custody just minutes after he allegedly shot and killed the victim.
The teen suspect, who has since been charged as an adult, is scheduled to appear at the Barrow County Court hearing via video from the juvenile detention center.
His initial court appearance came one day after his father, Colin Gray, 54, was indicted on a string of charges connected to the shooting, including allegations that he gave his son the weapon used in the massacre as a Christmas present last year.
Investigators are still working to determine the boy's motive for the massacre and whether there were any additional red flags since authorities first visited his home a year ago.

Investigators said authorities visited Gray in May of last year after the FBI received a tip that he had made online threats about carrying out a school shooting.
At the time, the boy denied having any intention of carrying out such a threat, according to the sheriff's report.
The father, who was also interviewed, told police he had a hunting gun at home but had not shown it to his son. Officers urged the father to keep the gun in a locked place and advised him not to send Colt to school “until this issue is resolved.”
However, investigators later shelved the case after conflicting evidence about the source of the social media posts prevented them from making any arrests, the sheriff's report states.
Despite the police visit, law enforcement sources told The Post that the father bought a Colt AR-style assault rifle as a Christmas gift just a few months later.
Meanwhile, a search of Gray's home following Wednesday's mass murder uncovered documents hidden in his bedroom that detailed his obsession with other school shootings, including the 2018 Parkland massacre at Marjory Stoneman Douglas High School. Law An enforcement official told CNN..
It was not immediately clear what Gray had read or written about the shooting.
Gray is charged with four counts of murder in the deaths of two students, 14-year-old Mason Schermerhorn and Christian Angulo, and two other teachers, 39-year-old Richard Aspinwall and 53-year-old Christina Irimy.
