Rebecca Aylward murder: Sentencing of Joshua Davies, 16
A 16-year-old boy who battered his former girlfriend to death is due to be sentenced on Friday for her murder.
Rebecca Aylward, 15, from Maesteg, was lured into a wood in Aberkenfig, near Bridgend, in October 2010.
Joshua Davies denied murder, blaming his friend, but was convicted by a 10-2 majority verdict in July.
Rebecca's mother, Sonia Oatley, has called him "pure evil" and she wanted him jailed "forever". The sentencing will be at Swansea Crown Court.
The court previously heard Davies sometimes hated Rebecca and a friend offered to buy him breakfast after suggesting that he "get rid of her".
The jury was told during the four-week trial that she died of head injuries caused by a rock, and was found still wearing new clothes bought for her the day before her death.
Her mother reported her missing when she failed to arrive back at the family home in Maesteg, near Bridgend.
Her body was found face down in the woods the next day.
An order banning the identification of Joshua Davies was lifted after he was convicted.
At the time Mr Justice Lloyd Jones said Davies would be in custody for a long time, and he would have to decide on the minimum period in detention before he could be considered for parole.
In an interview with BBC Radio 5 Live Rebecca's mother Sonia Oatley said: "I don't ever want him to come out.
"I want him to be locked away forever so that he won't do this to another person, because I am convinced he will do it to another person."
