A 7-year-old boy was killed while waiting for the bus in Pennsylvania. The driver who struck him apparently did not realize they had hit him and kept driving, police said. It comes days after another bus stop crash in Indiana. Alivia Stahl, 9, and her brothers, Xzavier and Mason, died in that incident. And in Florida, seven people, including five kids, were taken to a hospital after a car hit people at a bus stop. InsideEdition.com's Leigh Scheps has (http://twitter.com/LeighTVReporter) more.
