Amanda Knox, who was cleared of killing British student Meredith Kercher in Italy after four years in jail, says she has written to convicted murderer Lucy Letby in prison, the Daily Mirror reports. The American, who is working on a podcast on the UK case, says she would like to meet or speak to Letby, the former nurse serving a whole life prison sentence for murdering seven babies and attempting to murder seven others in 2015 and 2016.
