A former assistant football coach at North Cobb High School was arrested last week for allegedly “sexting” a 17-year-old girl earlier this year.

According to an arrest warrant, Ryne Thomas Thackston “on March 5, 2013, did send and receive sexually explicit photographs, via text messaging, to and from a 17-year-old female.”

The warrant goes on to allege that Thackston, 28, “sent two separate digital images of his penis to the victim” and “received numerous digital images and videos of the victim” that “showed the victim nude or partially nude and engaged in lewd acts and sexually-explicit content.”

The warrant did not specify whether the teen was ever a student of Thackston’s.

Thackston was booked into the Cobb County Jail on Friday and released Saturday on $20,000 bond. He is charged with felony sexual exploitation of a child.

According to Thackston’s public Facebook page, he has coached wide receivers at his alma mater since 2008.

Doug Goodwin, a spokesman for Cobb County Schools, said Thackston was a substitute teacher and “community coach,” but was not a full-time employee of the system. He has not worked in any Cobb school since March, Goodwin said.

Thackston is not currently listed on the North Cobb High website as being a member of the coaching staff.
