The wife of a US diplomat who returned to the U.S. after a fatal crash in the U.K. under diplomatic immunity was charged by British authorities on Friday.  

Anne Sacoolas has been charged with causing the death by dangerous driving of 19-year-old Harry Dunn, the Crown prosecution Service (CPS) told the family, said family spokesman Radd Seiger.

Saccolas crashed into Dunn’s motorbike after leaving Royal Air Force Croughton – an airbase used by the U.S. Army – on Aug 27, killing the teenager.
