A Christmas rifle, possible warning signs and 41 seconds of gunfire: jurors weigh Colin Gray's fate

Prosecutors say a Georgia father could have stopped his 14-year-old son from carrying out a school shooting, and they want jurors to convict him. On Monday, the trial enters its third week and jurors are preparing to deliberate. Prosecutor Patricia Brooks said Monday that the father saw warning signs and still gave his son a rifle. The defense says the real blame sits with the teen, and says no one could foresee the attack. The shooting killed two students and two teachers in 41 seconds. The boy faces dozens of charges. The father also faces murder and manslaughter counts.
