Derry on Bloody Sunday resembled the wild west's Dodge City, the wife of a US sailor has told the Saville Inquiry.
Susan Hanson, who was living in the Bogside with her three children in 1972, told how she and other relatives cowered in her aunt's flat when soldiers began firing after a civil rights march through the city.
She recalled seeing a boy of between 12 and 16 running across waste ground with a soldier in pursuit, before he was caught by four or five other soldiers, who beat him with rifle butts.
"The boy was then held up by one soldier on each side. I could see he was covered in blood," she said. "Next I saw the soldier who had been chasing aim his rubber bullet gun directly at the boy and I saw him shoot the boy in the stomach at very close range".
Mrs Hanson said she thought the boy was dead as she saw him thrown into an army troop carrier.
