An international expert panel has found there is no evidence to support the conviction of British serial killer, Lucy Letby, in a detailed report released this week.
She's serving 15 life sentences for the murder of seven babies by poisoning them with insulin and pumping air into their feeding tubes.
Letby was also found guilty of attempting to murder seven more.
The former nurse has been twice refused permission to appeal her convictions, and a public inquiry is underway in the UK on the basis of her guilt.
Professor Geoff Chase from the University of Canterbury is an adviser to the panel on bioengineering.
