One of the state agencies involved in the ongoing investigation of alleged sports wagering violations by Iowa and Iowa State athletes announced there is no evidence suggesting the integrity of any contest involving the schools was affected by gambling interests. That’s according to the Iowa Racing and Gaming Commission. A total of seven current or former athletes at the two schools were criminally charged this week. All seven are charged with tampering with records and all are suspected of placing bets on contests involving their own schools. Four are alleged to have wagered on games involving their own teams.
