When two policemen called on Graziella Marota on 20 June last year she had a mental image of her son Andrea trapped in the wreckage of a crashed car. It was a moment she had been dreading since the 23-year-old accepted a job that was an 80 km drive from the family home.
The officers sat Marota down and told her the worst news a parent can hear: her child was dead. She screamed and sobbed. Then she looked at her watch and had a flash of hope.
