A mum who was admitted to Whiston hospital with sickness and pneumonia was given too much paracetamol during her stay.
Laura Higginson died two weeks later from multi-organ failure, sepsis and Gitleman's syndrome - a rare genetic condition.
Her husband, Anthony Higginson, claims he was not informed that Laura, 30, was given too much paracetamol in hospital before her death. The 47-year-old had hoped the Crown Prosecution Service would charge staff at the hospital for giving her the wrong dosage.
