Former Westpac Pacific Fair home finance manager David St Pierre has confessed to cheating elderly and vulnerable customers out of millions of dollars in a dodgy investment scheme run on the Gold Coast between 2008 and 2013. The former award-winning employee pleaded guilty to three counts of using his position at Westpac dishonestly, with the intention to gain an advantage for himself or others. The loans totalled about $2.5 million. St Pierre was originally charged with seven counts of fraud and was expected to face an eight-day trial later this month, with 11 witnesses to give evidence.
