 Investigators are still here in the neighborhood. The shooter's house remains blocked off, but they've been going door to door, interviewing neighbors to see whatever they can learn. The kid, I just, I haven't talked to him much. Like, nobody really knows him. He sticks to himself. He had no criminal record, no mental health history. The FBI has gained access to his phone, but sources are still telling us his motive remains a mystery, the shooting a crime without a cause.
