SIOUX CITY, Iowa (AP) – A northwest Iowa man accused of sexually abusing his wife and forcing her to terminate pregnancies has pleaded not guilty to charges. The Sioux City Journal reports the 54-year-old man entered the written plea Monday in Buena Vista County District Court. He is charged with two counts of second-degree sexual abuse, five counts of forced consent to termination of human pregnancy, two counts of assault while participating in a felony and one count of tampering with a witness.

The Associated Press is not naming the man to protect the woman’s privacy. Police say the man forced his wife between October 2012 and April 2014 to take pills that resulted in the termination of two pregnancies. The woman told police her husband threatened her with a machete during sexual assaults.
