A 2010 Wartburg alumna was charged Oct. 18 with four charges of sexual exploitation of students by a school employee.
Ashley Anderson (Ritter) taught math at Aplington-Parkersburg High School.
The Associated Press reported Anderson resigned after an investigation began last month.
She turned herself in Oct. 19.
According to the criminal report by the Iowa Department of Public Safety, “Anderson engaged in sexual conduct during the 2011-12 school year.”
There were four students who engaged in sex acts with Anderson, according to the criminal report.
Several Wartburg alumni declined to speak about the arrest.
