A large amount of money was reportedly found in the hotel room of the man linked to the murder of Singaporean architect Audrey Fang in Spain.

Mitchell Ong, who was identified on April 20 by Spanish media as a suspect in the case, was also said to be wearing €1,000 (S$1,450) shoes, and his social media posts show that he had a penchant for the opulent.

On an archived version of his defunct website, where the 43-year-old offered financial advice, Ong claimed to be an "expert", with clients spanning chief executives, celebrities, the heads of banks and even regulators from the Monetary Authority of Singapore.

Among the achievements he listed were boasts of cashing out cryptocurrency investments and losing 15kg of body fat.

He also said he was the "sole Singapore representative" in 2018 to attend the 10X Growth Conference in Las Vegas and 10X Business Boot Camp in Miami.
