A former middle school gym teacher was arrested Monday for a sexual relationship with a 15-year-old student, the Georgia Bureau of Investigation said Monday. Shawnetta D. Reece, 40, of Blairsville, was sexually involved with the student in 2013, the agency said in a news release. Reece was arrested after the Union County Sheriffs Office received information on the alleged relationship, and asked the GBI to assist with the investigation.
