A 35-year-old Texas woman accused of having sex with a 14-year-old boy and then claiming to be pregnant from the relationship may have worked as a substitute teacher at least once in the boy’s classroom, a school official said.

Bexar County Sheriff's Office Amanda Sotelo, 35.

Amanda Sotelo, a resident of Von Ormy, was booked into a Bexar County jail on Nov. 1 on a charge of indecency with a child, Louis J. Antu, spokesman with the Bexar County Sheriff’s Office, told NBC News. Bond was set at $75,000.

School district officials learned of the allegations Oct. 31 after the boy's mother alerted them of the relationship, Anne Marie Espinoza, spokeswoman for the Southwest Independent School District in San Antonio, told KSAT-TV.

Excerpts from the affidavit:

Sotelo stated that the relationship developed over time. She and the victim were both going through problems and confided in each other. It wasn’t until the end of this last school year that they began having a sexual relationship, ‘like grown-ups’ … She further admitted that she and the victim had sex about once a week. Sotelo further stated that she found out she is pregnant when she went to the emergency room the first week of September. Sotelo further stated she loves the victim and he loves her.

"She's in jail but that's about the only thing we've heard. We've got a lot of family problems going on right now," Johnny Lopez, Sotelo’s son-in-law, told KSAT.com.

Lopez said Sotelo is married, and her husband was out of town. They have other children.

Espinoza confirmed that Sotelo had worked as a substitute in several of the district’s schools, and possibly, substituted at least once in the boy’s classroom, KSAT.com reported.

Esponiza told NBC News district officials refused to further comment.
