The US diplomat's wife who was involved in a crash that killed Harry Dunn told him she would get help after the collision – before waving down another car to assist so she could comfort her children, Sky News has learnt.
A source close to Anne Sacoolas told Sky News she takes responsibility for the crash and wants to meet 19-year-old Harry's parents to apologise.
She accepts she was driving on the wrong side of the road and is "terribly, terribly sorry for that tragic mistake", the source said.
Mrs Sacoolas is said to have stayed at the scene after the crash outside an RAF base in Northamptonshire in August, and spoke to Mr Dunn – who had been riding a motorcycle – to tell him that she would call for help.
She waved down another car which pulled over, allowing Mrs Sacoolas to return to comfort her young children who were in her vehicle, the source said.

According to the source, Mrs Sacoolas stayed at the scene until the ambulance had arrived and police allowed her to leave.
She is said to have provided a statement at the scene and met with Northamptonshire Police at her home the following day.

Mrs Sacoolas returned to America three weeks after the crash after being granted diplomatic immunity.
The Foreign Office says she no longer has diplomatic immunity because she has returned home.
Harry's parents, Charlotte Charles and Tim Dunn, have travelled to the US in the hope of meeting Mrs Sacoolas, but say she must first agree to return to the UK.
Ms Charles told a news conference in New York: "It's the only right thing to do.
"It's the only humane thing to do. And we would hope then that we can try to start to move forward and the UK justice system do whatever they feel is right."
Ms Charles said the family are willing to work with police and ask for Mrs Sacoolas to be given a suspended sentence for death by careless driving, rather than death by dangerous driving.
"We were going to ask for a suspended sentence so that we didn't take away from her children, although she's robbed us of one of ours"," she added.
Mr Dunn also called on US President Donald Trump to help secure justice for Harry.
"Our boy died and he deserves to have some justice. That's all we want,"Read More – Source
