A Laurel Highlands School District teacher was arrested after an investigation into an alleged months-long inappropriate relationship with a student. Fayette County District Attorney Richard Bower announced the arrest of Ashley Thurby Kolesar at a news conference Friday. Kolesar is facing three felony charges following a state police investigation into her alleged relationship with a 17-year-old boy in which they exchanged more than 6,500 text messages from September of last year through January of this year. At the center of the investigation is a conversation that Kolesar had with another student. Bower said Kolesar recorded a conversation without the student’s knowledge and sent it to the 17-year-old, violating wiretapping laws. She is facing charges of intercept communications, disclose intercepted communications and criminal use of a communication facility.
