MANNING, Iowa [KCCI] — A former western Iowa teacher has been sentenced to 33 years in prison after pleading guilty to a slew of sexual abuse and lascivious acts charges. 24-year-old Cassidy Kraus was a teacher in the IKM-Manning Community School District in Carroll County, when she was arrested last October and accused of sexually abusing three boys between the ages of 13 and 14.

In January, she pleaded guilty to one count of third-degree sexual abuse, two counts of lascivious acts with a child and three counts of dissemination and exhibition of obscene material to minors. Investigators say in addition to engaging in sexual activity with the minors, she also sent obscene material over Snapchat.

On Tuesday, Kraus was sentenced to the maximum sentence of 33 years in prison and a total fine of $5,400 plus 15% criminal surcharge. She will also be required to register as a sex offender for the rest of her life.
