Killer UK nurse Lucy Letby jailed for the rest of her life

Some of those she attacked were twins – in one case she murdered both siblings, in another, she killed two of three triplets, and in two instances she murdered one twin but failed in her attempts to kill the other.

“This was a cruel calculated and cynical campaign of child murder involving the smallest and most vulnerable of children,” said the judge, James Goss, who sentenced her to life imprisonment with no prospect of release.

“There was a deep malevolence bordering on sadism in your actions … You have no remorse. There are no mitigating factors.”
