HARRY Dunn's parents and twin continue to seek justice as it emerged Interpol have issued a Red Notice for Anne Sacoolas.
The diplomat's wife now faces arrest if she leaves the US as she is accused of killing the teen with her car in a crash near RAF Croughton.
Who are Harry Dunn’s parents?
Charlotte Charles and Tim Dunn were left shattered by the tragedy that saw their son Harry die in the motorbike crash.
The US embassy went on to confirm that Ms Sacoolas was driving on the wrong side of the road before the head on crash with Harry, 19, on August 27, 2019, near the RAF base in Northamptonshire.
She then claimed diplomatic immunity and was able to return to the US and has since not returned to the UK.
Ms Sacoolas was charged with causing death by dangerous driving last December.
The parents now have fresh hope for justice after Interpol issued a Red Notice.
Charlotte and Tim were allegedly told she is now "wanted internationally" in an email sent by Northamptonshire Police.
A Red Notice is a request to global law enforcement organisation to locate a person pending extradition, surrender, or similar legal action.
On its website, Interpol states it "is an international wanted persons notice, but it is not an arrest warrant".
Ms Sacoolas now faces new pressure, but Charlotte has said "we shouldn't have to be going through this".
Foreign Secretary Dominic Raab told US Secretary of State Mike Pompeo in January that Ms Sacoolas had to come back to the UK to face trial.
But an extradition request submitted by the Home Office was rejected by Pompeo.
Boris Johnson has warned US President Donald Trump that failing to extradite Ms Sacoolas would be a "denial of justice".
Charlotte and Tim had a high profile meeting with Trump on October 15, where the US president attempted to get them to come face-to-face with their son's alleged killer in an extraordinary summit at the White House.
Trump even held hands with Charlotte as he ambushed her with the prospect of meeting Ms Sacoolas who was waiting nearby - but the grieving couple refused.
The mum and dad described Trump's move to bring Ms Sacoolas to the West Wing as "inappropriate" and said such a meeting should only take place in Britain.
Who is his twin?
Harry 's heartbroken twin brother Niall, 19, couldn't leave the family home for six weeks following his death.
Niall had only just started seeing a couple of his friends again before the Covid-19 lockdown began, his mum said.
Charlotte described the family as being “deprived of the ability to grieve”.
She also recalled the last time she saw her son, when the keen biker rode out to visit Niall at his new home.
"I drove past him on my way home from work at 7.10pm," she said.
"He nodded to me. I put up my hand and thought I’d see him in a couple of hours.
"Well I did, but he wasn’t alive the next time I got to..."
What have his parents said about his death?
Charlotte and Tim appeared on Good Morning Britain on May 12, 2020, following the announcement of the Red Notice - describing it as "very emotional".
Tim said: "For me it came out of the blue, I wasn’t expecting it at all.
"My understanding is she is now a wanted fugitive if she leaves America.
"She can be arrested and sent back to the UK to stand trial. So, it’s a massive step for us as a family.
"It’s been a really hard time this lockdown. You have more time to think so you reflect on stuff, so it makes it harder.
"This news is great. I’m sure it’s going to be helping us down the line. It’s a good thing.”
Breaking down as he talked about lockdown further, Tim added: “It’s a struggle, it really is a struggle.”
Charlotte went on: "[It’s] pretty rough most days, I’ve got to be honest. It’s a very emotional time as it is but to be in lockdown again, because we voluntarily went into lockdown really after losing Harry.
"We had only sort of got our lives back for a little time, for a matter of weeks, when the coronavirus hit. So, we are struggling.”
Fighting back tears herself, she added: “You can’t offload to anybody each day because you can’t see them… to not have those hugs and those cuddles that you really need at a time like this is far, far more difficult than I even thought it would ever be at the beginning, I’ve got to be honest.”
Speaking about the Red Notice, Charlotte said: "She should never have gone back to the US in the first place.
"But the one major thing for me that came of this, when I read the Interpol notice, it encourages us and confirms to us that the UK authorities are finally on the same page as us, because they cannot issue a red Interpol notice to anybody, to anyone who was or is covered by diplomatic immunity.
"So that gives us confidence that finally after the eight months of the nine after losing Harry, and the fighting we have done, that the UK authorities are clearly on the same page as us to have taken the decision to put that red Interpol notice out."
The devastated parents also appeared on This Morning on October 21, 2019, after landing from the meeting President Trump.
The grieving pair said they just wanted "the truth" over their son's death.
Charlotte made an appeal to Ms Sacoolas and said: "Just get on the plane and come back to the UK. We are not horrible people."

The pair said "we didn't feel it was right" to meet with Ms Sacoolas despite the plan by Trump.
Sobbing Charlotte said Ms Sacoolas should be brought back to the UK to face justice: “It’s the right thing to to do. It’s the humane thing to do.”
Charlotte said Ms Sacoolas - a mum-of-three - should also do so to set an example of moral behaviour to her own children.
