A 27-year-old Nebraska woman has been given five years of probation following her conviction for having sex with her 15-year-old stepson.

The woman was sentenced for sexual assault. She’d pleaded no contest after prosecutors lowered the charge and dropped another. She was sentenced on Wednesday in Hall Country District Court.

The Post is not naming the Grand Island woman to protect the identity of her stepson.

Police say the boy was 15 when his stepmother began having sex with him. Investigators say the boy’s father called police to report he had seen his wife having sex with the boy, who is 16 now.

State law prohibits people 19 or older from having sex with anyone under 16 years old.
