FREMONT, Neb. (AP) — A December sentencing has been scheduled for a 21-year-old woman who bore a child after having sex with a 13-year-old boy.

Online court records say Brianne McIntosh, of Omaha, pleaded no contest to felony sexual assault of a child and intentional child abuse. Her sentencing is set for Dec. 19 in Dodge County District Court.

Authorities say McIntosh was 19 in May 2014 when she had sex with the boy. Under Nebraska law, people 19 and over cannot have sexual contact with people under 16.

State authorities have placed the little boy with his grandmother, who is helping his now 16-year-old father raise him.
