Human Rights Watch noted it "fell far short of the transparency, impartiality and thoroughness required by international law".
The army report said Rachel Corrie "was struck as she stood behind a mound of earth that was created by an engineering vehicle operating in the area and she was hidden from the view of the vehicle's operator who continued with his work. Corrie was struck by dirt and a slab of concrete resulting in her death."
Tom Dale, a British activist who was 10m away when Corrie was killed, wrote an account of the incident two days later.
He described how she first knelt in the path of an approaching bulldozer and then stood as it reached her. She climbed on a mound of earth and the crowd nearby shouted at the bulldozer to stop. He said the bulldozer pushed her down and drove over her.
"They pushed Rachel, first beneath the scoop, then beneath the blade, then continued till her body was beneath the cockpit. They waited over her for a few seconds, before reversing. They reversed with the blade pressed down, so it scraped over her body a second time. Every second I believed they would stop but they never did."
