A school bus owned by D and operated by one of its employees, ran over and killed 6-year-old Lori Sharp; she had just gotten off the bus and was walking in front it when she was run over. D was charged with homicide by vehicle. D filed a motion to quash the information against it. The offense charged could be committed only by a natural person, not by a corporation. The lower court granted D's motion to quash. The court held, sua sponte, that the information issued against D was insufficient. The Commonwealth (P) appealed.
