A Georgia man convicted in connection with the Apalachee High School shooting is sentenced to 15 years in prison. Multiple outlets report that the father provided his teenage son with an AR-15-style rifle and ammunition that the teenager later used to kill four people at the school and wound others. Prosecutors and the sentencing judge found the father repeatedly failed his son, including by giving the assault rifle to a troubled teen and leaving it unsecured in the boy’s bedroom. Sources also describe evidence that the teenager displayed psychological problems and a fixation on school shootings before the attack.

The sentence is described as the culmination of Georgia’s first prosecution in which a parent is convicted of second-degree murder for a mass shooting committed by their child. Courthouse News and other outlets say the father was convicted on charges including second-degree murder and involuntary manslaughter, with the judge imposing 15 years. Coverage across outlets is consistent that the conviction and sentencing follow the firearm the father supplied being used in the attack at Apalachee High School.
