SOUTH SIOUX CITY, Neb. (AP) — A former employee at a South Sioux City school has been sentenced to 90 days in jail for sending nude photographs to a 15-year-old student.

28-year-old Cecilia Hermosillo worked as a paraprofessional at Gateway to Learning and resigned last September. Gateway to Learning is an alternative high school in South Sioux City.

Police began investigating last year when a school resource officer reported a post on Facebook referencing nude photographs sent by a school employee to a student. Police say they were able to obtain the pictures from the 15-year-old boy.

Hermosillo turned herself in after an arrest warrant charging her with enticement by electronic communication device was filed. She pleaded no contest to attempted child abuse in April.
