A crowd of people at Gordon Park in Cleveland watched as Fischer cut the walleye open and found weights and walleye fillets stuffed inside.
As part of a plea deal, Runyan and Cominsky pleaded guilty to cheating and unlawful ownership of wild animals and agreed to three-year suspensions of their fishing licenses. Cominsky also agreed to give up his bass boat worth $100,000.
Prosecutors agreed to drop attempted grand theft and possessing criminal tools charges.
Both men are scheduled to be sentenced May 11. Prosecutors plan to recommend a sentence of six months' probation and later ask for an expungement of their convictions if they successfully complete their probation, said James Gallagher, an assistant Cuyahoga County prosecutor.
The plea is Cominsky's first step toward moving on with his life and taking full responsibility, said his attorney, Kevin Spellacy. A message seeking comment was left with Runyan's attorney.
According to search warrant affidavits, five walleye contained lead weights and fillets. Officers from the Ohio Department of Natural Resources confiscated the fish as evidence.
They would have received a little over $28,000 in prizes for winning the tournament.
Court records also said that Runyan and Cominsky were investigated near Toledo in the spring of 2022 after being accused of cheating in a different walleye tournament. According to a police report, a prosecutor concluded that although the men may have cheated, there was not enough evidence to charge them.
