Has the FBI identified the mystery person caught on video planting pipe bombs at both Republican and Democratic headquarters around Washington? And is it a woman? Surveillance videos are key in this investigation -- the largest in FBI history. Every frame is being studied - including how the mystery figure walks. And a five-year-old boy was waiting for the school bus when a car knocked him down - instantly killing him. But it wasn't just any driver behind the wheel... It was his grandmother. And cops allege she was under the influence of drugs and alcohol.  Plus, if President Trump's eyes look a little heavy, there's good reason. His VP... JD Vance says he never sleeps. But is it starting to catch up with him?  And concern for Ariana Grande in the wake of that scary incident where a crazed fan jumped the barricade at the Wicked premiere in Singapore. Some worry it was triggering for Ariana since she suffers from PTSD.
