McMINNVILLE, Tenn. —  The lawyer for a former Warren County elementary teacher accused of having sex with a 13-year-old boy pleaded not guilty for his client Wednesday.

A Nov. 15 trial date has been set for Pamela Rogers Turner (search), 27, who is charged with 15 counts of sexual battery by an authority figure and 13 counts of statutory rape (search), all involving the same boy.

Turner teaches physical education and coached girls basketball at Centertown Elementary, a Warren County school with grades kindergarten through eight in McMinnville.

District Attorney General Dale Potter said investigators believe some of the offenses happened at the school and some at the boy's home.

Turner was recently divorced from Chris Turner, who is the head boys basketball coach at Warren County High School, according to the Southern Standard newspaper in McMinnville.

Conviction on all counts could be punished by up to 100 years in prison. But Potter said it was more likely that a conviction would mean a minimum of a year to several years in prison.
