A Canadian mining company and its president and CEO claim in a lawsuit against Wynn Resorts Ltd. that the Las Vegas casino company failed to investigate the source of funds gambled and lost by a California man.

Toronto, Ontario-based James Bay Resources Ltd. and its president, Stephen Shefsky, allege in the lawsuit that while on probation, between January 2018 and June 2019, former decathlete David Bunevacz lost an estimated $3.8 million at Wynn Las Vegas and that some of those funds came from Shefsky and his company.
