Inquiry Finds UK Hospital Could Have Stopped Letby Murders Earlier
Lucy Letby was a nurse who worked at a hospital in northern England.
She was convicted of killing seven babies and trying to kill seven more.
Prosecutors said she harmed babies by using insulin, air injections, or milk.
Letby says she is innocent, and some experts have questioned her convictions.
A public inquiry examined whether the hospital responded properly to concerns about her.
Its chair said hospital leaders did not act quickly enough.
The inquiry said some deaths might have been stopped if safeguarding steps had been taken earlier.
It recommended better safety rules for hospitals and babies.
The inquiry did not decide whether Letby was guilty or innocent.
Inquiry chair Kathryn Thirlwall said a “complete failure” to protect babies allowed Lucy Letby to murder seven newborns.
The report said some deaths could have been prevented if hospital leaders had acted sooner after suspicions arose.
Letby was convicted of murdering seven babies and attempting to murder seven others, and maintains her innocence.
The inquiry did not assess Letby’s guilt or innocence, focusing instead on the hospital’s response and safeguarding failures.
Recommendations include stronger safeguards for insulin, cameras for cots and incubators, and an NHS protocol for suspected deliberate harm.
