Carl Saunders was a criminal associate of Warren Fox. In November 2007, Warren's girlfriend Louise Summers contacted Carl to see if Warren was still involved in crime. Carl later informed Louise that Warren's secrecy was due to the fact that he was planning a surprise engagement party for the pair.
In February 2008, Carl and his associate Anthony started hanging around Warren, and overheard Jack Osborne telling Warren that he had the £100,000 to buy Warren's share of The Dog in the Pond. Carl and Anthony then took the Osborne family hostage. Newt called the police and the pair attempted to make an escape after shooting Darren Osborne; but whilst Anthony was able to escape, Carl was caught. Warren was later informed that Carl had received a prison sentence of four and a half years.
