Girl, 5, stood yards from car bomb before fatal blast
The picture, showing the girl waving to runners taking part in the half-marathon right beside the booby-trapped vehicle, was released by detectives as they continued to question two men over the murder of the young Catholic officer.
Police believe the high explosive device had already been planted when the image was taken in Omagh, Co Tyrone, on Saturday afternoon. Two hours later it detonated with devastating consequences when 25-year-old PC Kerr got into his black Ford Mondeo to go to work.
