A mother-of-three was run over in broad daylight before being dragged under the wheels of a car and left dying on the street, her son told a court.
Paul Wandrum, 20, also described how the female driver of the silver car had reversed it over Margaret Borris three times after knocking her down, then drove away.
Mr Wandrum was giving evidence at the trial of Rona MacKenzie at the High Court in Glasgow.
