AIKEN – An Aiken County school teacher has been arrested for allegedly engaging in sexual activity with a 14-year-old.

Aiken County Sheriff’s Office arrested and charged Tammy Joy Key, 38, of Cottage Street, with four counts of lewd act and four counts of criminal sexual conduct with a minor, Sgt. Dave Myers said in a news release.

Investigators believe Ms. Key had sexual activity with the child between August 2005 and March 2006 at her Graniteville home. She also is accused of committing lewd acts on the victim between August 2005 and September 2005 at Leavelle McCampbell Middle School, where she teaches math.

She has been placed on administrative leave until the Aiken County school board is able to make a decision on her pay with the county, said Cecelia Davidson, associate superintendent for administration.

Dr. Davidson said the alleged victim has been a student in Aiken County, but is not enrolled at Leavelle McCampbell.

Ms. Key is being held at the Aiken County Detention Center.
