Expat Scots jailhouse lawyer proved prison pal accused of murdering cops was innocent
An expat, who was expelled from Australia over organised crime links, has helped a man convicted of murdering two police officers overturn his wrongful conviction. David McCulloch, 73, played a key role in assisting Jason Roberts, 41, in a fight to clear his name over the shooting of sergeant Gary Silk and senior constable Rodney Miller in 1998.
