IRNA - US Park Police has shot dead an Iranian national after a short chase into Fairfax County, Virginia on Nov. 17, it was reported on Wednesday.

The man died Monday (Nov 27) night after 10 days on life support, and the man�s family said he was unarmed when he was shot.

Bijan C. Ghaisar was an accountant for his father�s firm.

US park police said they pursued his Jeep sport-utility vehicle on the evening of Nov. 17 because it had been involved in a hit-and-run accident on the George Washington Memorial Parkway in Alexandria, Va., and the pursuit ended in the Fort Hunt area of Fairfax County.

Ghaisar�s family said in a statement released to The Washington Post that Ghaisar was shot three times in the head and suffered irreversible brain damage.

Ghaisar�s family said he had no weapons in his vehicle. �The reason for the murder of our son has yet to be determined,� the family said, �though no reasoning could possibly justify the actions of the one or more Park Police officers involved in this unthinkable act.�

The family�s statement said that Ghaisar, �a first-generation, American-born citizen of Iranian heritage, was peaceful and avidly anti-violence. He was unarmed. He presented no threat to anyone.�
