Father of Teen Suspect Charged in Georgia School ShootingThe father, Colin Gray, was charged with four counts of involuntary manslaughter, two counts of second-degree murder and eight counts of cruelty to children, the authorities said. An official said the charges stemmed from him “knowingly allowing his son” to have a weapon.

Colin Gray, the father of the 14-year-old accused of killing two teachers and two students at his Georgia high school, was arrested and charged on Thursday with second-degree murder in connection with the state’s deadliest school shooting, the Georgia Bureau of Investigation said.

In addition to two counts of second-degree murder, Mr. Gray, 54, was also charged with four counts of involuntary manslaughter and eight counts of cruelty to children, according to a statement. At a news conference on Thursday night, Chris Hosey, the G.B.I. director, said the charges were “directly connected with the actions of his son and allowing him to possess a weapon.” He declined to offer much more detail, other than to note that Mr. Gray was in custody.
