A British nurse, who wrote a note stating "I am evil," was found guilty on Friday of murdering seven newborn babies and trying to kill another six in the neonatal unit of a hospital in northwest England where she worked.

Lucy Letby, 33, was convicted of killing five baby boys and two baby girls at the Countess of Chester hospital and attacking other newborns, often while she was working night shifts, in 2015 and 2016.

The verdict, following a 10-month trial at Manchester Crown Court, makes Letby one of Britain's most prolific serial killers of children. She was found not guilty of two attempted murders while the jury were unable to agree on six other suspected attacks.
