EAST ORANGE — Authorities have identified the 21-year-old city woman who was struck and killed by a motor coach bus while crossing the street this morning with her young son. The victim, Christie Noble-Ross, was struck by a Coach USA bus at about 7 a.m., near the intersection of Main and South Harrison streets, said the Essex County Prosecutor’s Office, which released her name this afternoon. She was pronounced dead at the scene. The child, who is 3, was transported to the hospital but was not hurt, authorities said. The driver of the bus stopped after the accident, said Katherine Carter, a prosecutor’s office spokeswoman. No charges have been filed at this time, the office said, but the investigation is ongoing. Coach USA operates scheduled bus routes, motorcoach tours, charters and city sightseeing tours in various states, according to its web site. In New Jersey, the company runs commuter and local bus operations, Newark Airport express shuttles and charter and contract services, the web site said.
