Nine-year-old Bradley Livingstone was always looking out for his little sister Ellen.
Last night, those who knew the siblings were mourning the loss of two innocent children.
A woman who lived in the same street described Bradley and Ellen as "nice little kids". She said Bradley was "always looking out for his little sister and walking her to school".
Another woman who also lives in the street said Bradley and Ellen were "lovely wee kids. It's just horrible."
The children attended St Leonard's School, where many staff and students gathered yesterday to pay their respects.
