A trail of text messages have led to the arrest of a Coweta County teacher, who is accused of having sex with a 15-year-old student, Channel 2 Action News reported.

Dorothy Dixon, 29, is charged with one count of child molestation, authorities said. Dixon was a contract employee at Northgate High School, working with troubled teens as a special education teacher, officials said.

Coweta County Sheriff Mike Yeager said Dixon’s husband alerted them to the relationship.

"Apparently he had found where she had been sending emails or sexting messages. He thought she was having an affair with another man. Come to find out, it was actually a 15, now 16-year-old individual that this person apparently taught in school," Yeager told Channel 2.

Dixon is being held in Coweta Count Jail.
