A housewife has been convicted of laundering more than HK$11 million in criminal proceeds from her husband after she claimed it came from his decoration business. Her son was acquitted of a similar charge, while her husband remained at large. The family of three were together accused of laundering a total of HK$39.5 million. In the District Court yesterday, Judge Andrew Chan Hing-wai found Siu Kam-lin, 51, guilty of one charge of dealing with the proceeds of an indictable offence. Judge Chan described as 'unconvincing and incredible' Siu's claim that she believed the money that went through her bank account from 2004 to 2007 had come from the decoration business. It was no more than a small business, he said, citing her earlier descriptions of her husband making drawings on A4 paper on a tea table without a drawing board and while sitting on a sofa. Thirty invoices for materials for one project in March 2007, for example, totalled no more than HK$5,100, he noted. The size of the funds, the way the money was handled and the lack of information about its origins convinced the judge that those were proceeds of an indictable offence. Siu turned a blind eye to the criminal funds in her account and gave an unconvincing excuse, he said. Siu and her son, Ip Ming-fung, 25, each faced one count of dealing with the proceeds of an indictable offence, while Siu's husband faces three. Siu received money frequently and in large amounts, with one transfer of nearly HK$1 million in August 2005. Ip received HK$12,000 to HK$35,000 at a time, except for two larger sums in January and August 2007. His father transferred HK$771,200 in to his account from 2005 to 2007. Judge Chan said a reasonable person might not conclude that the funds Ip received were the proceeds of an indictable offence and let him go. In mitigation, lawyer David Khosa said there was no evidence that Siu had benefited from the money. She was often in arrears and had remortgaged her home to pay credit card debts, he said. Siu worked at a petrol station from 2006 to 2007, he said.
