Calvert City, KY – The Calvert City Council plans to update their city employee drug-testing policy following an employee's arrest for manufacturing methamphetamine. Last week police determined a meth lab sparked a brush fire behind Calvert City Elementary School. Officers arrested long time city employee Lexie Shayne Greer Friday for conspiracy to manufacture the drug. The Marshall County Tribune-Courier reports Greer allegedly supplied the materials to make meth to state inmates who were on work release. City officials have since suspended their work-release program and police have charged three inmates for making meth. Calvert City Mayor Lynn Jones says the council plans to strengthen their drug-testing policies, which he says have some issues.
