Falls City, Neb. ? The conflicting worlds of Matthew Koso collided Wednesday inside a tiny Richardson County courtroom.

In one world, Koso is an ordinary 22-year-old factory worker who goes home each night to his wife. In the other, Koso faces rape charges after impregnating and then marrying the now 14-year-old girl, who is expecting their first child in less than a month.

Koso did not say a word Wednesday as Richardson County Judge Curtis Maschman set his arraignment in district court for Aug. 30 – two days after his wife is due to give birth.

The Associated Press is not naming the girl.

Koso’s mother, Peggy, and older brother, Nick, sat in the courtroom during the hearing. His wife was not present. She started school Wednesday morning at Falls City High School, where she is freshman.

After the girl became pregnant, her mother gave permission in May for Koso to take her daughter to Kansas, which allows minors to get married with parental consent.

Nebraska Atty. Gen. Jon Bruning has charged Koso with first-degree sexual assault, punishable by up to 50 years in prison.

A Falls City Police investigator testified that the case began last May when the state Health and Human Services system asked the department to look into a report that the girl might be pregnant.

Nebraska requires people to be at least 17 before they can marry.

Kansas does not have a minimum age restriction on marriage as long as both parents approve or it is approved by a district court judge.

If only one parent approves, the judge must approve, as well.

On Wednesday, Gov. Kathleen Sebelius said she was asking legislators to establish a minimum age for marriage. She said the age should be 16, 17 or 18, “so we don’t, after the fact, cover up abuse of children.”
