DECATUR, MEIGS COUNTY (WRCB) – The Meigs County School Board says a teacher allegedly involved with a student has resigned.

According to school officials, Dave Mason, a Meigs County High School teacher and baseball coach, allegedly involved in "improper conduct with an 18-year-old student."

The school board says it is closing its investigation into Mason. Because the student involved was 18-year-old, no criminal charges are expected.
