British detectives questioned nurse Lucy Letby, who is serving life in prison for killing seven babies, about the deaths of several more infants.
Cheshire Police said on Wednesday that Latby was being questioned in prison about the child’s death and a “non-fatal fall” at the Countess of Chester Hospital, where she worked, and Liverpool Women’s Hospital, where she trained as a student.
The force said Letby was interviewed “under caution”, meaning the interview was recorded and could be used in future prosecutions.
The 34-year-old nurse was sentenced to life in prison with no chance of parole for killing seven children and attempting to kill seven others while working as a neonatal nurse at Countess Chester Hospital in northwest England in 2015 and 2016.
Prosecutors said she harmed the children in ways that left little trace, including injecting air into their bloodstreams, feeding air or milk into their stomachs through nasogastric tubes, poisoning them with insulin, and interfering with breathing tubes.
Detectives are now reviewing the care of around 4,000 babies who were admitted to the hospital while Letby was working as a neonatal nurse.
Letby, who testified that he never harmed the child, continued to proclaim his innocence and tried unsuccessfully to appeal his conviction.
Some scientists and legal experts have questioned aspects of the circumstantial and statistical evidence used in his trial, and supporters have pushed for a review of the case.
A judge-led public inquiry is being held to identify why babies were dying in the neonatal unit and to examine the hospital’s failures to stop the deaths early. It is not reviewing Latby’s beliefs.
Senior Pediatrician Dr. Countess of Chester Hospital Neonatal Unit. Stephen Brere told the inquest last month that Letby may have killed or assaulted several children before killing his first known victim, a premature twin boy known as Baby. A, in June 2015. “On reflection, I think it’s possible that Letby didn’t start being a killer in June 2015, or start harming children in June 2015,” he said.
