May 13, 1990 - December 26, 2005: Age 15
Jane Creba was a 15-year-old high school student. She was out shopping on Boxing Day (December 26, a traditional day for big sales in Canada) with her older sister on a busy street in Toronto. She left her sister for a moment to skip across the street to an athletic wear store when a gunfight erupted. Creba was hit by one bullet that entered and exited her upper torso. She was rushed to the hospital, and died during emergency surgery.
In the confusion after the accident, Creba was the first to be taken to hospital as her injuries were the worst. Her older sister, whom she had left on the other side of the road, did not at first understand that she had been hurt. When she couldn't find Jane, she called her mother, who called police. By the time the family reached the hospital, Jane had died.
The incident is thought to have been related to a street gang feud, and certainly had nothing to do with Jane or with any of the other people injured. Altogether 10 young men, including three teenagers, were charged with murder or manslaughter in relation to Jane's death and the injuries of six others.
