A teenager who murdered two teachers and two students at a Georgia high school in 2024 has been sentenced to life in prison without the possibility of parole. Colt Gray, 16, pleaded guilty last Friday to 55 counts, including murder, for the September 4, 2024, shooting that claimed four lives.

During his sentencing hearing Tuesday, prosecutors presented audio recordings of phone calls between Gray and his mother, Marcee Gray. In these calls, she described fan art and online attention her son was receiving, to which he reportedly responded with excitement. His mother told him she would print some of the posts for him and mentioned creating a "Colty Shrine" in his honor.

Gray also reportedly expressed interest in a journalist requesting to make a documentary about the case, saying, "Yes. Go for it."

Prosecutors argued that Gray's conversations with his mother and his documented interest in school shootings indicated a premeditated attack. Investigators testified that Gray idolized other mass shooters and communicated with individuals online about his admiration for them. Messages read in court included Gray stating, "I want people to remember the pain I caused and research me for hours." He also referenced Nikolas Cruz, the Parkland school shooter, in a message stating, "My love for Nik has formed into something in which I can find no other resort that can prove my love and affection towards him."

Forensic psychologist Dr. Kevin Richards also testified that Gray had fascinations with Adam Lanza, responsible for the Sandy Hook Elementary School shooting, and James Holmes, who carried out a mass shooting at a Colorado movie theater. A "shrine" to Nikolas Cruz was also described as being kept by Gray next to his computer.

Gray was convicted in the deaths of teachers Richard "Ricky" Aspinwall, 39, and Cristina Irimie, 53, and students Mason Schermerhorn and Christian Angulo, both 14. Another teacher and eight students were wounded in the attack.

This case also marks a precedent in parental accountability for a child's crimes, as Gray's father, Colin Gray, was previously found guilty of murder and manslaughter in March for purchasing the firearm and storing it unsecured.
