By Rachel Sharp For Dailymail. A female middle school teacher allegedly had sex eight or nine times with a year-old student at her home, while her own child was also present in the house. Ellarea Silva, a year-old science teacher at Northwestern Middle School in Zachary, Louisiana, turned herself in to police on Thursday following allegations she had sex with the boy on multiple occasions last summer, authorities said. The illegal fling began when Silva emailed the teen using both their school email addresses, an arrest report stated. The communication quickly switched to their personal emails 'so the school could not track' it, the report said.
