BRAINERD, Minn. - Organizers of a Minnesota ice fishing tournament says an investigation into alleged fraud has cleared three Ohio men who won prizes, including a brand new pickup truck.

The Brainerd Jaycees Ice Fishing Extravaganza says the three family members have passed lie detector tests and will be allowed to keep their prizes, which also includes $1,000 and an ice auger.

Ivan Lyogky of Hartville, Ohio, and his sons Stephan and Rostik were tested separately by a licensed polygraph examiner and no deception was detected. Stephan Lyogky won the contest and the pickup with a northern pike that weighed 3.10 pounds.

“We want everyone to know that we always take matters like this very seriously. We are pleased with the results of this inquiry and appreciate the cooperation of the Lyogky family to ensure to the sporting community that our event is fairly administered,” said 2018 event chairperson, Shane Meyer, “We congratulate the Lyogky family, as well as all other anglers that participated in the contest this year. What we do makes such an enormous difference in our community.”

Contest organizers say they received an anonymous tip that raised suspicions about the legitimacy of the Lyogkys' fish. About 12,000 anglers participated in the $150,000 contest Jan. 27.
