n Stuart (right), the registered child-sex offender whose sale of test-prep software for high school students has drawn consumer complaints from around the country, went free on $5, 000 bail today.

Cedar Hill police arrested him Thursday after I reported that Stuart hadn't disclosed he was running the SAT and ACT Prep Center near a day care and middle school in Coppell.

I initially checked his background after he told me, with no explanation, that he preferred to use the last name Miller.

His business still faces inquiries from the Texas attorney general over the consumer complaints and from the state comptroller for not paying sales tax.

THIS JUST IN from comptroller spokesman R.J. DeSilva: "The company didn't comply with our request to apply for a sales tax permit. So we will be in the process of estimating an amount of liability they owe. The taxpayer can then contest the amount in an administrative hearing at the Comptroller's office."
