A west Nashville meth-cooking operation is out of business and four people are behind bars following a raid Monday evening.
Metro police said a several month investigation into Robert Martin's alleged drug ties led to Monday's execution of a search warrant at Martin's home on Indian Creek Road off River Road.
Seized were three grams of processed methamphetamine, eight firearms, 17 marijuana plants and evidence of products commonly used to manufacture meth such as empty pseudoephedrine packages, ether cans used as starter fluid, stripped lithium batteries, and acetone, among other items.
Martin, 40, and his girlfriend, Barbara Henry, 29, are each charged with initiating the process to manufacture meth, possession of meth for resale and Crooks with Guns law violations.
Two other men at the residence were also arrested.
Police said James Dixon, 42, a suspected meth cook, is charged with initiating the process to manufacture meth, promotion of meth manufacture and a Crooks with Guns law violation.
Anthony Wilson, 20, is charged with possession of marijuana for resale and a Crooks with Guns law violation.
