Dorian Johnson, who says he was with Brown, has told a much different story. He has said the officer ordered them out of the street, then grabbed his friend's neck and tried to pull him into the car before brandishing his weapon and firing. He says Brown started to run and the officer pursued him, firing multiple times.
Attorney General Eric Holder has said federal investigators have interviewed witnesses to the shooting. A person familiar with the matter, who spoke on condition of anonymity because the investigation is ongoing, said federal authorities have interviewed Johnson. Holder spoke by telephone Thursday with Brown's family.
