near Rishworth Moor in West Yorkshire. Lying face down in tall grass on a natural turf shelf nine metres above the carriageway, she was discovered by a driver who'd stopped in a nearby layby. Lesley had been stabbed twelve times in the upper shoulder and back: one wound had penetrated her heart. There were no defensive wounds, and a time of death could not be calculated. None of her clothing or possessions were disturbed, but her money was missing and semen was found on her clothing and underwear.
