An estimated $2million in marijuana plants was discovered by an off-duty officer in Grundy County on Wednesday, July 30. The Gruetli-Laager site is thought to be the largest ever discovered in Tennessee. The operation was very sophisticated with a well, generators, and miles of irrigation hoses that served multiple grow sites. The Grundy County Sheriff’s Department, the DEA, and the THP are clearing the area using ATV’s, helicopters, and military vehicles.
