During a court appearance on Tuesday, a teenager accused of executing a fatal shooting at a Georgia high school appeared drastically transformed, as shown in recent photographs.

Colt Gray, now 15, arrived in court with his hands cuffed, sporting a preppy look that included a quarter-zip sweater, collared shirt, khakis, and glasses. His hair was neatly cut and styled slicked back, presenting a stark contrast to his previous disheveled, shoulder-length, bleached orange hairstyle.

The young suspect, charged with the tragic deaths of four people, appeared almost unrecognizable. His previous appearance, marked by untamed orangey locks, was a far cry from his current polished demeanor.

Aisha Broderick, the attorney assigned to represent Gray since October, informed the court that they are awaiting a medical evaluation of Gray. This assessment, expected to conclude by the end of February, will significantly influence the defense’s strategy and the filing of additional motions, as reported by CBS Atlanta.

The evaluation is scheduled to be completed by the end of February, according to the outlet.

In May, Gray’s previous defense attorney, Alfonso D. Kraft, signaled to Barrow County Superior Court Judge Nick Primm that the teen was moving toward pleading guilty after a visit with a psychologist.

“We should be good to go,” Kraft said at the hearing.

It’s unclear why Gray changed attorneys.

Gray has been charged as an adult for the Sept. 4, 2024, shooting at Apalachee High School that killed two teachers and two students.

Educators Richard “Ricky” Aspinwall, 39, and Cristina Irimie, 53, and students Mason Schermerhorn and Christian Angulo, both 14, were killed in the shooting.

Another teacher and eight more students were wounded — seven of them hit by gunfire.

Gray, then 14, was indicted on a total of 55 counts, including murder in the deaths of four people and 25 counts of aggravated assault.

Grand jurors also formally charged his father, Colin Gray, for allegedly giving his troubled son an AR-15-style rifle for Christmas — the weapon that Colt ended up using to carry out the terrifying slaughter.

The dad was hit with 29 counts, including two counts of second-degree murder and two counts of involuntary manslaughter.

Both father and son also face multiple counts of cruelty to children.

Charles Polhamus, the 14-year-old alleged gunman’s maternal grandfather, told The Post at the time that his former son-in-law, Colin Gray, should bear much of the blame for the bloodbath.

“Spending 11 years with that son of a bitch screaming and hollering every day — it can affect anybody,” Polhamus, 81, said of his 54-year-old ex-son-in-law, who was married to his daughter Marcee.

“He’s evil,” Polhamus said of the older Gray.

“They couldn’t, they didn’t survive in it,” he said of the family.

Colin Gray faces up to 180 years behind bars if convicted of the heinous crime, and Colt Gray faces up to life in prison. As a juvenile, he cannot be sentenced to death.

Investigators have testified that Colt Gray carried a semiautomatic assault-style rifle given to him by his father onto the school bus with the barrel wrapped in a poster board.

He allegedly left his second-period class and emerged from a bathroom with the rifle, shooting people in a classroom and hallway at the 1,900-student school.

The deranged alleged shooter also created a “shrine” to school shooters above his home computer, Georgia Bureau of Investigation Agent Kelsey Ward said in court.

Colt Gray will return to court on March 18.
