The father of school shooter Colt Gray has himself been jailed for 15 years for giving his 14-year-old son the guns he used to murder four people. Colt received a semiautomatic rifle and ammunition from his father as a Christmas present. During a second-period bathroom break, the teenager pulled the gun out of his bag in the bathroom and began shooting students and teachers in the hallway, investigators said. Ethan, like Colt, received a life in prison without parole sentence. 'Heck yes, because then I can show you all the pictures,' his mother, Marcee Gray, said.
