The father of a teenage boy accused of killing two students and two teachers in a mass shooting at a Georgia high school in 2024 was found guilty on Tuesday of second-degree murder and other charges.

After roughly two weeks of testimony, jurors deliberated for just a few hours before convicting 54-year-old Colin Gray on more than two dozen charges, including second-degree murder and involuntary manslaughter, related to the 4 September fatal shooting at Apalachee high school in Georgia.
