CBS Cleveland affiliate WOIO-TV says the tournament hosted fishermen from several surrounding states who competed to see which team could catch five of the heaviest walleye fish in Lake Erie.
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.
