"Another company, T2 Promotions, provided alcohol at both Beerfest and Whiskey and Wine Fest. T2 was owned by David Moritz, who passed away last year. A city of Bismarck spokesperson says a further look at the numbers says that the Rec and Leisure Show was charged half the rent price last year compared to competing vendors.
A Moritz family spokesperson says the boat dealership pays rent to a separate company, but not to the Event Center. The city forwarded their findings from Jeske to a special agent with the North Dakota Bureau of Criminal Investigations for possible felony charges. A BCI spokesperson tells KX news that right now, the investigation is still open, and the city has not started the search to hire a new director at the Event Center."
