B.C. gaming officials flag unusual betting in casino review Justine Hunter, The Globe and Mail · January 8, 2018 at 9:40 pm People identifying their occupations as “student” or “housewife” make up an unusually large share of B.C.’s high-rolling gamblers, prompting B.C.’s Attorney-General to question the source of millions of dollars flowing through the province’s casinos. Gaming officials audited a year’s worth of transactions at a single casino – Richmond’s River Rock Casino – looking for patterns that could shed light on money laundering by organized crime. Among the report’s findings were housewives whose bets were flagged as unusual because of the amount of cash they were bringing in, sometimes with stacks of bills in small denominations. One student alone bet $819,000 over the course of the year.
