Mrs Loyau-Kennett was a passenger on a number 53 bus which was travelling past the scene, and jumped off to check the soldier's pulse.
"Being a cub leader I have my first aid so when I saw this guy on the floor I thought it was an accident then I saw the guy was dead and I could not feel any pulse.
"And then when I went up there was this black guy with a revolver and a kitchen knife, he had what looked like butcher's tools and he had a little axe, to cut the bones, and two large knives and he said 'move off the body'.
"So I thought 'OK, I don't know what is going on here' and he was covered with blood. I thought I had better start talking to him before he starts attacking somebody else. I thought these people usually have a message so I said 'what do you want?'
