In court, Judge Mr Justice Dingemans paid tribute to Becky’s family for the dignity in which they had comported themselves during the trial.
He added the manner in which Hoare and Matthews had tricked Becky’s father Darren Galsworthy and his wife, Anjie, in the days following the murder was “particularly cruel and unusual”.
Judge Dingemans also said he believed the planned kidnap “was for a sexual purpose” and the couple’s understanding of proper conduct had been “corrupted and warped”.
