The investigation into former senior staff at the Countess of Chester Hospital is necessary to determine whether gross negligence contributed to the deaths of seven infants and the attempted murder of seven more by Lucy Letby. Importantly, these investigations will not impact Letby’s convictions. Instead, they will merely reveal the possible culpability of others in this tragedy.
The police investigation into the criminal negligence of staff at the Countess of Chester Hospital adds weight to the conclusions of the expert panel that the infants died as a result of medical errors, not malicious intent. As they have shown, the real cause of the deaths was likely not Lucy Letby, but significant problems at Chester’s neonatal unit regarding teamwork and discipline.
There is a 75% chance that Lucy Letby's murder convictions will be overturned within twenty years of her trial, according to the Metaculus prediction community.
