ANDERSON, South Carolina -- Ava Olsen always carries Mikey, the Ninja Turtle that belonged to her friend Jacob. When she looks at Mikey, she thinks that "Jacob's with me." Jacob Hall, the boy Ava imagined marrying, was six. In September of 2016, he was shot and killed on the school playground in Townville, South Carolina. The shooter was fourteen. Ava watched it happen. "I always try to forget it, but it doesn't work," she said. Mary and David Olsen, Ava's parents, now homeschool her.
