Jennifer Riojas, 27, a science teacher in Fort Worth, Texas, was pregnant when arrested for sexual assault in November after allegedly having sex with a 16-year-old student. The pupil came forward because he was worried that the baby was his. He told police they met in motels, and even had sex when he was in a hospital bed recovering from a football injury.  Riojas has denied all allegations.  She resigned from the school district, citing stress on her pregnancy due to the rumors, and not believing secondary education was here calling. A second student was also rumored to have had sex with Riojas.

Update Jan 17 2012:  Riojas pleaded guilty to having an improper relationship with a 16-year-old male student. She received six years deferred adjudication probation, and will not be able to teach again.  Regarding the father of her baby, Riojas attorney said, "if you do the math, the teenager could not be the child's father as their last sexual encounter was in January of 2009 and she gave birth exactly one year later".
