Court documents show Thao 'Sandy' Doan, 27, paid over $28,000 to the 14-year-old student after he threatened to share pictures with the police.
Doan taught math at Raul Quintanilla Senior Middle School in West Oak Cliff. She was arrested last Friday and she's facing a felony charge of improper relationship between an educator and student. She bonded out of jail on the day after she was arrested
The affair came to light after Cops received a complaint from the mother of the teen student. She found some suspicious text messages from her son to Doan which suggested he was blackmailing her. She told police her son was blowing cash supplied by the teacher on booze and drugs, according to an arrest affidavit cited by Dallas News.
One message allegedly read: "Aint b'sing watch ima start getting the pics and everything ready to show the cops. Right i aint playing." [SIC]
Police say a detective then interviewed Doan, who confessed to having sex with one of her students three separate times in a park in 2015 and again last month.
A search warrant affidavit confirmed she sent the student an image of her exposing her breasts and that the two engaged in explicit chat via texting, Instagram and app kik.
Doan claims she began receiving calls in January 2016 from someone she did not know threatening to expose the alleged affair.
The teacher who was arrested on Friday in connection with a suspected sexual relationship has been placed on administrative leave.
