All charges are expected to be dismissed for four former or suspended Iowa State athletes, according to a motion filed on Friday.
The prosecutor that is running the case said that the Iowa Division of Criminal Investigation superseded its powers by impermissibly using tracking software that detected whether betting apps were used at Iowa State athletic facilities.
"Due to this newly discovered evidence, the State no longer believes further prosecution in this matter is in the interests of justice," Matchan wrote.
The four athletes were accused of underaged gambling and for using proxies, most of them utilizing family members. More than two dozen Iowa State and Iowa athletes were criminally charged last year.
Brian Ohorilko, the director of gaming for Iowa's state commission, told the Action Network last year when the story broke that there were no indications that any games were compromised because these college athletes gambled on sports.
NCAA bylaws prevent athletes from wagering on any sport. Federal law prevents wagering by those under the age of 21.
