 I'm Mark Remillard. New police video showing the moment officers in upstate New York shot and killed a 13-year-old boy on Friday. Police in Utica say the boy ran from officers who tackled him to the ground. They say there was a struggle and that the boy pointed a gun at them, prompting an officer to fire and hit the teen in the chest. The gun was a replica, however. The boy's uncle today mourning his loss and pledging to fight for him.
