The United States Park Police officers who fatally shot a 25-year-old Virginia man last fall after a minor car collision and a brief chase fired at him at least nine times at close range, a video released on Wednesday shows.

The man, Bijan Ghaisar, died on Nov. 27 — 10 days after he was shot four times on the left side of his head, and once in his right wrist, one of his family’s lawyers said in a telephone interview on Wednesday.

Video of the shooting, which revealed new information about the closely watched case, was released by Edwin C. Roessler Jr., the chief of the Fairfax County Police Department. Fairfax County officers provided backup during the Park Police pursuit of Mr. Ghaisar, but according to the chief, they did not discharge their weapons.

In a statement, Chief Roessler justified the release of the in-car video by calling it “a matter of transparency to all in our community, especially the Ghaisar family.”
