About 6.30pm on Saturday 25 October 2003, Michael Marshall pulled up outside his South Yarra home with his five-year-old son in the car. A gunman ran at him and shot him in the head at close range.
Police had two men in custody within hours. A jury later convicted the man behind it. But Melbourne wasn't allowed to know his name for more than three years. So who was he, and why the secrecy?
