The parents of Harry Dunn, who was killed in a crash involving a US diplomat’s wife, are on their to way to America to publicise their son’s story.
The 19-year-old died in the crash in Northamptonshire on 27 August. Anne Sacoolas left the UK under diplomatic immunity despite being a suspect.
Her lawyer said the 42-year-old was “devastated by the tragic accident” and extended her “deepest sympathies”.
Mr Dunn’s mother, Charlotte Charles, said “sorry doesn’t cut it”.
The teenager’s parents said they would like to take up the offer to meet Mrs Sacoolas when they landed.
Mrs Sacoolas – who is reportedly married to a US intelligence official – was granted diplomatic immunity following the crash, but the Foreign Office said it no longer applied.
On Saturday, Foreign Secretary Dominic Raab wrote to Mr Dunn’s family to explain that the British and US governments now considered Mrs Sacoolas’s immunity irrelevant.
Home Secretary Priti Patel told The Andrew Marr Show earlier the situation had moved on over the last 24 hours and it was “right” that “co-operation takes place”.
“It is right that justice is served, that an investigation takes place, and that Anne Sacoolas actually does co-operate with investigation,” she said.
Northamptonshire Police said it was liaising with the Foreign Office and International Crime Co-ordination Centre about what to do next.
In a statement, it said it was “absolutely committed” to achieving justice for the teenager and his family.
A statement issued on behalf of Mrs Sacoolas, whose husband worked at RAF Croughton near the scene of the crash, said she had “fully co-operated with the police”.
It added: “She spoke with authorities at the scene of the accident and met with the Northampton police at her home the following day. She will continue to co-operate with the investigation.
“Anne would like to meet with Mr Dunn’s parents so that she can express her deepest sympathies and apologies for this tragic accident.”
Ms Charles and Harry’s father, Tim Dunn, will visit New York and Washington DC during their trip.
She told Sky News that – seven weeks after the death of her son – “sorry just doesn’t cut it” but she would like to take up an invitation to meet Mrs Sacoolas and would not be aggressive in that meeting.
What is diplomatic immunity?
About 23,000 individuals in the UK have diplomatic immunity, a status reserved for foreign diplomats and their families, as long as they do not have British citizenship.
It means that, in theory, they cannot face court proceedings for any crime or civil case.
However, where crimes are committed, the Foreign Office can ask a foreign government to waive immunity.
Diplomatic immunity is by no means restricted to those named on the Diplomatic List. Drivers, cooks and other support staff who have been accredited to Britain (“the receiving state”) have the same diplomatic status and immunity.
Mr Dunn’s parents have previously said they are considering civil action against Mrs Sacoolas.
The family’s spokesman Radd Seiger said they would be “engaging with the media and politicians as they reach out for support from all Americans and to ask them to put pressure on the US administration to do the right thing”.
On Friday, Prime Minister Boris Johnson said the US was “absolutely ruthless” in its safeguarding of Mrs Sacoolas following the decision to grant her diplomatic immunity.
He said although President Donald Trump was sympathetic towards Mr Dunn’s family, the US was “very reluctant” to allow citizens to be tried abroad.
Mr Raab said now that neither government deemed her immunity relevant, the matter was “in the hands” of Northamptonshire Police and the Crown Prosecution Service.
The police force previously said CCTV of the crash in which Mr Dunn died shows a Volvo travelling on the wrong side of the road.
