A man who gave his son the gun he used in a deadly high school shooting in Georgia has been sentenced to 15 years in prison. Colin Gray was convicted of charges including second-degree murder and involuntary manslaughter after his then 14-year-old son, Colt Gray, used the weapon to kill two students and two teachers at Apalachee High School in September 2024. Colt Gray was sentenced Tuesday to life in prison without the possibility of parole. Prosecutors say Colin Gray gave his son the rifle as a Christmas gift. The elder Gray is among a handful of American parents who have been charged after their children were accused in shootings.
