Authorities said a 30-year-old woman was arrested for having sex with a 16-year-old boy after the boy's mother discovered text messages that were sexual in nature on his cell phone.
Police said the mother arranged to meet with the woman, Heather Dawn Tinker Mastin, at the Krystal in Ooltewah to ask her about it.
A county detective, J.B. Ashburn, was sitting nearby where he could overhear the conversation.
Ms. Mastin admitted at the restaurant to having sex with the woman's son, it was stated.
The boy was then contacted and he admitted having sex with the woman for the last several weeks at her home on Sylar Road.
He said the trysts started the first of February.
Authorities said Ms. Mastin admitted having sex with the boy.
She was charged with aggravated statutory rape since there is more than an ten-year age difference between the two.
A $20,000 bond was set for her.
She is due in General Sessions Court on April 6.
