Man Convicted Of Sex Abuse Of 11-Year-Old Will Serve 25-Year Prison Sentence

Sibley, Iowa — A man will serve a 25-year prison sentence after his conviction on sexual abuse charges in Osceola County.

According to a criminal complaint filed with the Osceola County Clerk of Court’s Office by the county sheriff’s office, 34-year-old Dennis Thompson of Sioux Falls, SD was accused of sex acts with an 11-year-old girl.

In his statement, the deputy states that the victim disclosed to him and to a Department of Human Services worker that she had been forcibly raped by Thompson about one year ago. She told them that Thompson grabbed her arm, dragged her into his bedroom, and threatened to hit her if she cried.

Thompson was charged with second-degree sexual abuse, a class B felony; lascivious acts with a child, a class C felony, and assault with intent to commit sexual abuse, a class D felony. He also faced misdemeanor charges of indecent contact with a child, first-degree harassment, and indecent exposure.

In September, a jury found Thompson guilty of the second-degree sexual abuse and assault with intent to commit sexual abuse felony counts and the indecent exposure misdemeanor count. The charge of lascivious acts was dismissed.

On Monday, Thompson was sentenced to 25 years in prison on the sexual abuse count, with credit for time served. On the assault charge, he was sentenced to five years in prison, and one year on the indecent exposure charge. However, all three sentences are to be served at the same time. He also will have to pay fines and civil penalties, submit a DNA sample for profiling, and register on the sex offender registry.
