Koso Gets Sentenced To Prison Time

The Falls City man who married a 14-year-old girl and then pleaded guilty to sexual assault will serve time in prison. 22-year old Matthew Koso was sentenced this morning to 18 to 30 years in prison. Koso legally married the now 15-year old girl in Kansas after she became pregnant with his child.. The girl, Crystal Koso, gave birth in August to a baby girl. The controversial case prompted Nebraska's attorney general, Jon Bruning, to file charges against koso for having sex with and impregnating a minor. Koso originally pleaded not guilty to sexual assault in August, but his attorney said he advised his client to change his plea.
