Colin Gray is scheduled for sentencing after a jury found him guilty of second-degree murder and involuntary manslaughter for arming his son, Colt Gray, whose AR-15-style rifle was used in a mass shooting at Appalachee High School that killed two students and two teachers and wounded nine.Prosecutors say Colin Gray bought the rifle as a Christmas gift, supplied ammunition and accessories, left it unsecured despite repeated warnings about Colt Gray’s deteriorating mental health and violent behavior, and presented photographs and messages they say show escalating danger.Legal experts and prosecutors call the conviction a landmark because it is the first time a parent has been convicted of murder in a school shooting case; under Georgia law
Colin Gray faces 10–30 years on the murder count and the sentence will test whether courts will hold parents criminally accountable for arming minors.
