Police say charges are pending the results of the investigation.The school bus driver has been identified as Clarence Beamer, 59, of Philadelphia.Video from the scene showed the damaged bus on its side. There was damage to the hill and guardrail on the right side of the highway.Coincidentally, a number of Philadelphia police officers, recruits and family members of fallen officers were on board three buses that were travelling through the area at the same time.They were on their way to a police memorial service, also in in Washington, D.C., and were not involved in the crash.When they came upon the scene, they rushed out to help."Wonderful, wonderful help. They were assisting in patient care, and I believe they got everyone out," said Peter Quackenbush, chief of the Havre de Grace Ambulance Corps.Edie Ritchie was on one of those buses."We got off and started tending to the injured," she said by phone Monday afternoon. "It was total mayhem."She said they were actually late departing Philadelphia. Otherwise, they would have been far ahead of the bus that crashed."Everything happens for a reason," she said.Action News spoke with John Clark, whose daughter was among the students on board. He says, fortunately, she only suffered minor injuries."She's a strong young lady. She was more concerned for friends, her classmates, her teachers," he said. "One thing she shared with me, though. She thought it was kind of surreal. She thought she was dreaming."----------
