Trinity J Shockley, an 18-year-old Mooresville High School student, has been arrested on charges of conspiracy to commit murder and intimidation for threatening to commit terrorism at the school.

Colin Gray has been in custody since his arrest months ago. He has been indicted on 29 charges related to the attack allegedly perpetrated by his teenage son.

A judge has granted a $500,000 bond for the father of a 14-year-old boy who is accused of a deadly mass shooting at a Georgia high school.
