An anonymous person with detailed information about the suspicious disappearance of a British man in Brisbane 21 years ago may hold the key to solving the cold case. Police believe Steven Goldsmith was murdered around the time he disappeared in July 2000, and there are people who know what happened. A $250,000 reward is now being offered for information which leads to the conviction of those responsible. One person has made contact with investigators a number of times in the years since Mr Goldsmith's disappearance and last contacted police in 2006. The last confirmed sighting was on July 10, 2000 when Mr Goldsmith was seen on CCTV at the Commonwealth Bank ATM (pictured) in the Brisbane suburb of New Farm
