A Caddo Parish jury Tuesday took just over 90 minutes to convict a 65-year-old man of trying to defraud a Shreveport riverboat casino in February 2011.

Bruce Wayne Duffy, who has prior convictions in 1975, 1977 and 1987 for drug and theft offenses, faces up to 10 years in prison, as well as a fine of up to $3,000, after he was found guilty of issuing a worthless check for $1,500 or more. He will be sentenced at a later date.

The six-man jury found that on or about Feb. 22, 2011, Duffy requested a line of credit and casino markers to gamble at Sam’s Town Casino. However, the $20,000 in markers issued were not valid as they had been drawn on a closed account.

Jurors unanimously determined that Duffy intended to defraud the casino despite his contention he discharged his obligation in bankruptcy.

The case was before Caddo Parish District Judge Brady D. O’Callaghan. Duffy was defended by attorney Mary Harried. Prosecutors were Mekisha Smith Creal and Senae D. Hall of the Caddo Parish District Attorney’s office.

Duffy appeared before Judge O’Callaghan again briefly today, and was scheduled to return to court Sept. 8, 2016, for post-trial motions. After his conviction he was remanded to the custody of the Caddo Parish Sheriff’s office.
