Lufkin Cheerleading Coach Mary Ainsley Thigpen, 29 has been charged with second-degree improper relationship between educator and student. Thigpen began text messaging an 18-year-old male student during the 2015-2016 school year. The student informed Lufkin ISD police about the graphic nature of the texting. He said at one point, Thigpen's husband became aware of the text messaging, so the two switched to GroupMe and Snapchat to communicate, according to the affidavit.
