Four people were charged with methamphetamine trafficking in three incidents this week in Hall County, including one that authorities say involved a couple bringing an infant to a drug deal. The Multi-Agency Narcotics Squad set up sting operations for suspected meth traffickers, said Lt. Scott Ware. “We had phone calls and texts with our targets or our suspects, and in all three of these cases, locations were set up where they agreed to meet and bring the drugs to sell to a third party,” Ware said.
