Grandfather of 'blue-eyed boy' ISIS executioner, 11, reveals his guilt after the child was led into terror group's grip by his own mother

The grandfather of 11-year-old British boy JoJo Jones, who is believed to have appeared in a sickening ISIS execution video, has said the youngster is a 'lost soul' whose life is 'finished'.

 Terry Lynch, 56, revealed that his stepdaughter - the boy's mother - was taking drugs when she was brainwashed before becoming part of the terror group.

Mr Lynch raised Sally Jones, 47, as his daughter but is so furious about what she has done to JoJo he said the 'sooner she dies, the better'.

He spoke to The Sun after shocking footage appeared to show the boy taking part in an ISIS video.

And Mr Lynch, from Borough Green, Kent, was appalled and horrified after he saw the clip of the youngster holding a gun.

He told the newspaper: 'That is a wasted life. His life is finished. There is no way he came back to the normal world - it's terrible.'

Mr Lynch, who married Ms Jones' late mother Jacky, also helped looked after JoJo's older brother Jonathan at his home.

Speaking of JoJo, he added: 'He was a lovely little boy, gorgeous. He's a lost soul, you are never going to get him back.'

Ms Jones, from Chatham, Kent, fled to Syria three years ago and took her son - who was eight at the time - with her to the war-torn country.

The mother-of-two wanted to join Islamic State after meeting hacker Junaird Hussian and later married him.

The 20 year old was killed in August last year following a US air strike.n a shocking video released just weeks ago, five children where shown murdering a group of captured Kurdish fighters.
