A Dickson County High School teacher will not be in the classroom when the school year finishes this week after marijuana was allegedly found in her car. English teacher Molly Graham was placed on administrative leave pending an internal investigation after a routine drug sweep discovered marijuana inside her car in the faculty parking lot at the school. Director of Schools Dr. Danny Weeks said the 23rd Judicial District Drug Task Force, Dickson County Sheriff’s Office and Dickson Police Department were conducting a sweep using a drug dog when the canine alerted to a car in the parking lot. A search of the car turned up a small amount of what is believed to be marijuana and officers said the car belonged to the 46-year-old Graham. She was cited for simple possession of marijuana and is scheduled to appear in Dickson Municipal Court next month. She is on leave pending an investigation by the school system.
