The American woman accused of killing Harry Dunn has admitted driving on the wrong side of the road for "approximately 20 seconds" before colliding with the young motorcyclist.
A statement released by Anne Sacoolas's lawyers said she is "devastated" and "continues to grieve deeply" for Harry's family.

"Anne did not leave the scene until she was instructed to do so by the UK authorities."
US authorities asserted that Sacoolas had diplomatic immunity and, according to her lawyers, "deRead More – Source
