A North Platte man has been charged with 1st Degree Sexual Assault after he allegedly had sexual intercourse and impregnated a 15-year-old girl.

On August 7th, a sexual assault investigation by the North Platte Police Department was initiated after the Lincoln County Attorney’s Office contacted Police regarding a minor having sexual intercourse with an adult.

Authorities say the minor, now 17, requested assistance at the Lincoln County Child Support Office for financial support for her one-year-old child.

An earlier paternity test indicated that the suspect, Jamie Johnston, now 24, is the biological father of the child.

Nebraska State law requires minors to be 16-years-old to legally have consensual sex with a person over the age of 19.

In this case, the girl was 15 and Johnston was 22 at the time the act took place.

On September 4th, an Investigator met with Johnston and arrested him on the charge.  He was transported and jailed at the Lincoln County Detention Center.

1st Degree Sexual Assault is a Class II felony.
