Joan Grove was standing at an intersection in downtown Pittsburgh during rush hour. She was in her fifties at the time. While a bus was attempting to pass another car near the intersection, the driver of that commuter bus came close to the curb where Grove stood. The bus struck Grove, and she fell to the ground.
While lying on the ground, the bus’s rear wheel ran over her right lower leg. Grove suffered a crush injury to that leg. She later developed a MRSA infection and osteomyelitis, which led to the amputation of her leg.
Grove sued the Port Authority of Allegheny County claiming that its driver chose not to keep a proper lookout during rush hour. The defendant maintained that Grove had stepped into the bus’s path by standing on the outside curb margin.
