WINDER, Ga. -- The 14-year-old accused of fatally shooting four people at his high school in Georgia was expected to make his first court appearance Friday, a day after his father was also arrested for allowing his son to have a weapon.

According to arrest warrants obtained by The Associated Press, Colt Gray is accused of using a semiautomatic assault-style rifle to kill two students and two teachers at Apalachee High School in Winder, outside Atlanta. Nine people were also hurt in Wednesday’s attack. Authorities have not offered any motive or explained how Gray obtained the gun or got it into the school.

The teen's father, Colin Gray, 54, was charged Thursday in connection with the shooting, including with counts of involuntary manslaughter and second-degree murder, Georgia Bureau of Investigation Director Chris Hosey.

“His charges are directly connected with the actions of his son and allowing him to possess a weapon,” Hosey said. Colin Gray's first court appearance has not been set.

It’s the latest example of prosecutors holding parents responsible for their children’s actions in school shootings. In April, Michigan parents Jennifer and James Crumbley were the first convicted in a U.S. mass school shooting. They were sentenced to at least 10 years in prison for not securing a firearm at home and acting indifferently to signs of their son’s deteriorating mental health before he killed four students in 2021.

Colt Gray was charged as an adult with four counts of murder in the deaths of Mason Schermerhorn and Christian Angulo, both 14, Richard Aspinwall, 39, and Cristina Irimie, 53.
