Texas Teacher in Student Sex Scandal Is Pregnant

Nov. 22, 2010— -- A 26-year-old former high school science teacher who was arrested for having sex with one of her students is pregnant, amid speculation that her alleged victim may be the father.

Jennifer Riojas is out on bond after being arrested on Wednesday for sexual assault against a child under 17. The arrest came nearly a month after she resigned from her job as a science teacher at Carter-Riverside High School in Fort Worth, Texas.

Court documents detail a tawdry affair between student and teacher, with the two even taking to the teenager's hospital bed for sex at one point.

Fort Worth Independent School District spokesman Clint Bond confirmed that Riojas left her classroom on Oct. 19 and resigned two days later. Her resignation letter referenced her pregnancy.

ABC's Dallas affiliate WFAA reported that the paternity for Riojas' baby has not been established, but that the teenager came forward because he was concerned that he might be the father.

According to an affidavit filed in Tarrant County, Riojas's alleged victim told school officials that he was 16 years old when he began a sexual relationship with his teacher.

The affidavit details several alleged encounters between the two, including one instance of sexual intercourse in the teenager's hospital bed in early December 2009 when he was being treated for a sports-related injury.

The teenager, who was in Riojas' first-period class as a sophomore, told authorities that as he and Riojas got to know each other, she would attend his school football games and he would spend his lunch period in her class, according to the affidavit.

"The victim, now 17 years old, stated that defendant drove the victim to different hotels ... at which time the victim and defendant engaged in sexual intercourse," the document continued.

A hotel clerk in nearby Hurst, Texas confirmed to investigators that Riojas rented a room on Dec. 10, 2009 -- with a coupon --and again on Jan. 28, 2010.

Riojas could not immediately be reached for comment.

Texas Teacher Accused of Sex With Student Free on Bond

According to the affidavit, the Fort Worth Independent School District began investigating allegations that Riojas was having sex with a student in October this year.

Assistant District Attorney Dale Smith told ABC News that he could not comment on the case, including whether prosecutors would seek to determine whether Riojas' pregnancy resulted from the alleged relationship.

"We're continuing to investigate," he said.

Riojas, free on $20,000 bond, is next due in court Dec. 7. There is no defense lawyer listed in the case file.

Riojas started teaching at the school since August 2009, just months before the alleged affair began.

According to WFAA, news of the relationship has been the talk of the school.

WFAA reported that friends of the alleged victim as well as other students claim the relationship between the teenager and Riojas was common knowledge. "I heard some rumors, so I thought they were messing around," an unnamed student told the station. "I asked him too, and he said -- he was just laughing, so that's when I thought, yeah, he was messing around with the teacher."

The case is reminiscent of the Mary Kay Letourneau affair. In 1996, she was a 34-year-old married mother of four and Vili Fualaau was her 12-year-old student.

In what was among the first of many high profile teacher-student relationships, Letourneau gave birth to two daughters by Fualaau. Now a registered sex offender, she and Fualaau -- now in his late 20s -- are married. The couple made headlines last year by hosting a "Hot for Teacher" night at a Seattle bar.
