They have suggested sewage leaks on the neo-natal unit of the Countess of Chester Hospital could have harboured the bug and are to blame for the baby deaths. Crucially, Baby I’s post-mortem examination showed no evidence of pneumonia or any other inflammatory infection which would be expected if she had such a bacterial infection at the time of death. The court heard Baby I had been born 13 weeks early at the end of August 2015, weighing just 2lbs 2oz. The prosecution said Letby had injected Baby I with air, causing her to cry out in pain, moments earlier.
