The teenage killer of Ellie Gould stabbed her to death after she refused to be his girlfriend.

Police have said the attack on Ellie, also 17, was not random, confirming Ellie and Griffiths knew each other.

Both were studying A-levels at school.

On Thursday, Griffiths admitted in court to killing the Year 12 pupil and his case has been adjourned by Bristol Crown Court until November 8.

He has been remanded in custody and faces a mandatory life sentence.

Griffiths was said not to have been in any trouble with the police before the killing.

Griffiths’ identity was only revealed for the first time earlier this week after reporting restrictions were lifted.

Wiltshire Police Detective Inspector, Jim Taylor, said: “Ellie was murdered as a result of a violent attack.

“While I am pleased that Ellie’s family will not have to endure a lengthy trial process in court which would have caused them further distress, I know just how difficult this whole period has been for them.”
