Three people have been charged with marijuana trafficking following their arrest earlier this month. The charge follows an extensive investigation by the Saint Clair County Sheriff’s Office. St. Clair County Assistant Sheriff Billy Murray says, 60-year-old Ruth Brock, 60-year-old John Brock, Jr. and 28-year-old John Brock were each charged with drug trafficking. Investigators executed a search warrant at 550 Davis Drive in Ashville on the morning of February 11. Inside, they found 105 marijuana plants, a large amount of marijuana and "numerous" items of paraphernalia. The Brocks have bonded out of the Saint Clair County Jail in Ashville on $100,000 bond each. They are expected in court on March 16.
