Harry Dunn's family broke down in tears and hugged in the family kitchen as news come through that the wife of a US diplomat has been charged with causing his death.
In floods of tears they embrace each other tightly as the TV cameras roll and the eyes of the world watched the emotion pour out.
American spy's wife Anne Sacoolas, 42, has been charged with causing the death of the 19-year-old by dangerous driving.
She left the UK shortly after Harry was run down outside RAF Croughton, in Northamptonshire, on August 27 and subsequently claimed diplomatic immunity.
Still in shock and struggling to find the words, Harry's dad Tim said: "We believed and we believed and we believed and we've done it, we've got that charge, its amazing, absolutely amazing."
Later, speaking to reporters outside the headquarters of the Crown Prosecution Service, an emotional Tim said he was "still overwhelmed by the decision."
"I can't really say. I'm a bit speechless at the minute, I'm in shock from the meeting,"he said.
Reporters were also told that the extradition request for Mrs Sacoolas will be made before Christmas.
The CPS has today authorised Northamptonshire Police to charge Anne Sacoolas with causing death by dangerous driving.
Harry's mum Charlotte Charles said: "We feel that we have made a huge step in the start of achieving the promise to Harry that we made.
"We made that promise to him the night we lost him to seek justice thinking it was going to be really easy.
"We had no idea it was going to be so hard and it would take so long but we feel it is a huge step towards that promise we made Harry."
Mr Dunn added: "We set out for this to happen, for a charge to be brought from the start, and today we've got what we set out to get. It's a great day."
When asked what the family would be doing now, Charlotte replied: "Try and get some sleep. Try and spend time with the family. It's really that simple for us."
