CORPUS CHRISTI, Texas (AP) — A South Texas woman faces up to 30 years in prison for a babysitting scam in which she recorded her convicted sex offender boyfriend molesting a girl.

Rosa Linda Ganceres of Mathis pleaded guilty Wednesday to production of child pornography. Ganceres remains in custody pending sentencing by a federal judge in Corpus Christi.

Prosecutors say Ganceres and her boyfriend, Daniel Benson Billman Jr. of Aransas (uh-RAN'-zuhs) Pass, advertised online last summer as babysitters. Investigators say a woman hired to pair to watch her daughter, then Billman sexually assaulted the girl and Ganceres recorded the abuse.

Billman in January pleaded guilty to production of child pornography. Billman in March was sentenced to 50 years in prison.

Details weren't immediately available on Billman's previous convictions.
