On May 10, 2007, 16-year-old Blair Holt lost his very promising life when a gunman fired several shots at a rival gang member, on a packed CTA bus, and also struck Blair in the stomach. The killer, 18-year-old Michael Pace, confessed to killing him and was sentenced on Monday to 100 years in prison. Blair’s father, Ron Holt, talks about what this means for his family, and how he continues his mission for stricter gun control.
