An agency nurse has been found guilty of causing the death of a six-year-old boy by gross negligence.
Jack Adcock, who had Down's syndrome, was taken to Leicester Royal Infirmary in February 2011 suffering from vomiting and diarrhoea and later developed sepsis.
Portuguese-born nurse Isabel Amaro, 47, from Manchester, was found guilty of manslaughter after three days of deliberations at Nottingham Crown Court following a four-week trial.
During the trial, Amaro, who had worked with children for 20 years, accepted she breached her duty of care but denied that any of her failings significantly contributed to the youngster's death.
Dr Hadiza Bawa-Garba, 38, and nurse Theresa Taylor, 55, both of Leicester, are facing the same charge which they deny, claiming they acted properly in their care for Jack, of Glen Parva, Leicester.
The jury will continue their deliberations on Bawa-Garba and Taylor on Tuesday.
