LONDON (Reuters) - The chair of British public inquiry examining how Lucy Letby was able to murder seven babies in her care on Wednesday rejected calls for her investigation to be paused until a review body had considered if the nurse's convictions should be re-examined.

Former executives at the British hospital where Ms. Letby was a nurse requested that a judge’s inquiry into the killings there be suspended amid new evidence.

Judith Moritz, who has covered the Letby case from the start, takes us inside the evidence to piece together how events unfolded at the Countess of Chester Hospital - and why it took more than a year to stop a killer.
