HARRY Dunn begged "don't let me die" after being knocked off his motorbike by Anne Sacoolas in a killer crash.
In December 2019, Sacoolas was charged with causing death by dangerous driving over the death of Harry Dunn in a head-on smash near RAF Croughton on August 27, 2019.
Sacoolas had turned out of RAF Croughton and drove on the wrong side of the road for over 20 seconds
And back in October this year she pleaded guilty to causing the death of 19-year-old Harry by careless driving in the fatal road crash.
Today, Sacoolas virtually appeared at the Old Bailey for causing Harry's tragic death by careless driving.
She attended the sentencing hearing by video-link from Washington DC - as she also did when she pleaded guilty.
Prosecutor Duncan Atkinson KC said Anne Sacoolas told police at the scene she had "made a mistake" and that she was "so stupid".
Continuing his opening of the case, Mr Atkinson said: "The defendant remained at the scene and she spoke to police.
"The police observed that the defendant had her head in her hands and was crying.
"She told them she had 'made a mistake' and said 'I was so stupid'.
"The police confirmed that she complied fully with their requests at the scene.
"She acknowledged she was driving on the wrong side of the road."
Mr Atkinson added that a motorist who witnessed the harrowing scene said: "He was face down, but conscious. He repeatedly said 'don't let me die'."
Ms Sacoolas is the wife of US diplomat Jonathan Sacoolas who was stationed on the US intelligence base at RAF Croughton, Northamptonshire, in 2019.
Mr Atkinson said Ms Sacoolas drove 350 metres for some 26 seconds on the wrong side of the road after turning from the air base.
He added that she failed to recognise road markings which should have alerted her to this error.
The prosecutor told the court: "Faced with an oncoming motorcycle, there was no opportunity to avoid a head-on collision."
She said: "I started driving and a short distance.. ahead I remember seeing Harry, being confused, and the accident happening all, you know, at the same time really."
Having got her children out of the car, she went to help the stricken motorcyclist.
She said: "He made a comment that he was driving on his side of the road.
"It was when I got my kids to the side of the road that I realised what happened.
"It wasn't until that point that I realised that I had driven on the American side of the road versus UK side."
Mr Atkinson told the court: "Faced with an oncoming motorcycle, there was no opportunity to avoid a head-on collision."
Sacoolas had diplomatic immunity asserted on her behalf by the US government after the crash and was able to leave the UK 19 days after the incident.
In a statement read by her lawyer Ben Cooper KC, Sacoolas said she was "deeply sorry for the pain I have caused".
Harry Dunn's mother broke down as she told the court her son's death "haunts me every minute of every day".
Sacoolas appeared to wipe away a tear as Harry's mum Charlotte Charles read her victim impact statement at the Old Bailey.
Speaking about how her son's death had affected her, Mrs Charles told the court: "My world turned upside down on August 27 2019.
"My beautiful son Harry, twin brother of Niall, is gone and is never coming back.
"For 19 years, I had the enormous privilege and joy of nurturing and raising Harry who was the light of my life before he was so senselessly and cruelly taken from us.
"Harry just disappeared out of my life that night, shattering my existence forever.
"I didn't make it to the hospital in time before he passed and the thought of that haunts me to my core.
"I beat myself up over and over again - if I had left work on time that night, I would have been able to delay him leaving the house so that he wouldn't have been travelling along the same road as Anne Sacoolas.
"Although I have my other beautiful son Niall with me and the rest of my family, there is an intense feeling of emptiness in the pit of my stomach without my cheerful Harry around."
