samples taken for culture and sensitivity (bacteriology) tests. In his responses, he failed to reveal the existence of these withheld test results. Clark was convicted by a 10–2 majority verdict on 9 November 1999, and given the mandatory sentence of life imprisonment. She was widely reviled in the press as the murderer of her children. Despite recognition of the flaws in Meadow's statistical evidence, the convictions were upheld at appeal in October 2000. She was imprisoned at Styal women's prison, near her home in Wilmslow, and then Bullwood Hall women's prison in Hockley in Essex. The nature of her conviction as a child-killer, and her background as a solicitor and daughter of a police officer, made her a target for other prisoners. Her husband left his partnership at a Manchester law firm to work as a legal assistant nearer the prison, selling the family house to meet the legal bills from the trial and first appeal. Successful second appeal Later, it came to light that microbiological tests showed that Harry had a colonisation of Staphylococcus aureus bacteria, indicating that he had died from natural causes, but the evidence had not been disclosed to the defence. This exculpatory evidence had been known to the prosecution's pathologist, Alan Williams, since February 1998, but was not shared with other medical witnesses, police or lawyers. The evidence was unearthed by her husband from hospital records obtained by the divorce lawyer Marilyn Stowe, who provided her services free of charge because she felt that "something was not right about the case". It also became clearer that the statistical evidence presented at Clark's trial was seriously flawed. For her second appeal a report regarding the medical evidence was provided by Sam Gulino, a prosecution forensic pathologist for the State of Florida, US. He commented scathingly about the poor quality of the pathologists' work in these cases: Her case was referred back to the Court of Appeal by the Criminal Cases Review Commission, and her convictions were overturned in a second appeal in January 2003. She was released from prison having served more than three years of her sentence. Statistical evidence The first trial was widely criticised for the misrepresentation of statistical evidence, particularly by Meadow. He stated in evidence as an expert witness that "one sudden infant death in a family is a tragedy, two is suspicious and three is murder unless proven otherwise" (Meadow's law).
