LAKE CHARLES, Louisiana β Federal regulators have directed a Louisiana casino to sever ties with a former executive who they say failed to alert auditors and potential investors about fraud allegations. The person in question is now a consultant for the casino.
The National Indian Gaming Commission ordered the Coushatta Tribal Gaming Commission to suspend the license of Todd Stewart, who was general manager of the Coushatta Casino Resort in Kinder. The federal agency issued the directive in a Sept. 8 letter to the tribe, according to documents the Illuminator has obtained.
Shawna Castellano, a regional director with the National Indian Gaming Commission, wrote in the letter that her agency received a complaint last year that alleged former Coushatta tribal chairman Johnathan Cernek had misused gaming revenues. Those claims were later confirmed through an accounting firmβs audit of the casino, the letter said.
Earlier this month, the Louisiana Legislative Auditor published a report from a separate independent audit that indicated the Coushatta tribeβs leadership did not keep track of credit card use, with no receipts to show for purchases totaling more than $100,000 over a two-month spending period in 2024 that was reviewed.
Cernek resigned as tribal chairman in August 2024, KPLC-TV reported. Tribal council member Crystal Williams was named acting chairperson after Cernek stepped down, and new tribal chairman David Sickey was sworn in June 13.
Williams and tribal secretary treasurer Kristian Poncho have not responded to questions from the Illuminator about how financial concerns were reported to them, when they were made aware of potential fraud involving the use of casino credit cards or the quality of information council leadership received from management and auditors during that time.
Sickey did not respond to multiple requests for comment, and tribe spokeswoman Mary Patricia Wray declined to respond before the deadline for this report.
According to Castellanoβs letter, the commission interviewed Stewart on June 5 and learned he did not βdisclose suspected fraud to the external auditors during the [fiscal year] 2023 annual audit of the financial statements.β Stewart also didnβt discuss the matter with βthe potential lender of a $150 million construction loan the Coushatta Casino was in the process of obtainingβ until the loan was actually secured, the letter said.
The Coushatta Casino Resort broke ground on a new $150 million hotel in March 2024.
The regulatorβs three-page letter, sent to Coushatta Tribal Gaming Commission Chairwoman Pam Bass, also alleges Stewart was βunsure of how many credit cards were associated with the Casino bank accounts and uncertain of who was using the Casino credit cards.β
Stewart has not responded to phone calls or emailed questions from the Illuminator about how financial concerns were reported to him, his suspicions of Cernek regarding credit card spending or the scope of his current role as a consultant for the casino.
The National Indian Gaming Council declined to provide additional information about its actions involving the Coushatta tribe.
When the Illuminator reported earlier this month on the audit findings posted on the Legislative Auditorβs website, the tribal council provided a statement through its spokeswoman. It said the councilβs credit cards had been eliminated, and the tribe had adopted a formal expense reporting and reimbursement policy.
Hours after the Illuminator published findings from the audit, the report was removed from the Legislative Auditorβs website. Officials said they were discussing whether the state should have posted it on their website in the first place. An attorney with the auditorβs office said federal regulations allow tribes to opt out of having their audit reports made public.
According to the letter from federal regulators, the Coushatta Tribal Gaming Commission must issue a hearing notice for Stewartβs potential license revocation and notify regulators of its decision within 45 days.
Members of the tribeβs gaming commission could not be reached for comment.
