A witness told the inquiry yesterday she saw a man fire shots from a handgun shortly after soldiers shot and injured a youth, Damien Donaghy. He is believed to have been the first gunshot victim on Bloody Sunday.
Ms Teresa Bradley also said she was unhappy that this and other aspects of her account of the events had been omitted from a statement she gave to the Northern Ireland Civil Rights Association (NICRA) several days after the shootings.
Ms Bradley described attending the Civil Rights march on January 30th, 1972, with her husband, Seamus. At William Street she saw soldiers on a wall by the Presbyterian church and someone remarked that they looked like they could start shooting.
As people retreated from a confrontation farther down the street, she heard shooting and saw a boy beside her who had been shot in the leg. She realised the soldiers were firing live rounds.
Her husband helped carry the boy away and, as she awaited his return, she saw a gunman on the first-floor walkway at the back of the Kells Walk flats. "The man was standing completely alone and was pointing a handgun straight in front of him with arm outstretched, and was firing it in the direction he was facing," she said.
Ms Bradley also described a later incident, about a mile away in the Brandywell area, when she and a cousin came across a group of boys beside a car. "I recall that I looked in the back seat of their car and saw a lot of guns which I remember were rifles," she said. The guns were piled on the back seat.
Ms Bradley said she had read through a statement dated February 4th, 1972, which she gave to NICRA. It was not a complete version of what she told them at the time. She recalled mentioning the civilian gunman that she saw, and the boys with the guns in the car.
Another witness, Mr Eugene Lafferty, told Mr Christopher Clarke QC, counsel to the tribunal, that he was not prepared to discuss the death of his brother, Eamonn, who was shot by soldiers five months before Bloody Sunday.
Eamonn Lafferty was reported to have been an officer in the IRA's Derry Brigade.
The witness said he knew nothing about the IRA, and he had seen nobody shooting at the army on Bloody Sunday. His brother was already dead in August 1971.
The inquiry continues today.
