Three units at the Walnut Street Apartments on East Railroad Street remained quarantined while a company assesses the danger after drug agents busted a meth lab Wednesday afternoon. An agent with the 23rd Judicial District Drug Task Force said unit D3, where eight “shake and bake” meth-cooking operations were discovered, and the units on either side are being evaluated for cleanup procedures with samples being tested to determine how much chemical saturation is present. The units were evacuated Wednesday after the agents found five active and three non-active cooking operations while responding to a report of a strong chemical odor. The apartment was rented by 33-year-old Candice Nicole Barnhill, who was being held on $5,000 bond. Also arrested in the apartment was 24-year-old Nicholas Shane Dugan of Glendale Road in White Bluff. He was being held on $25,000 bond. 25-year-old Candace Hedge Christy of Rickert Street in Dickson was arrested after she allegedly jumped out a bedroom window and fled the apartment before police caught her when she ran inside a nearby home. She was being held on $20,000 bond. All three face charges of initiating the manufacture of methamphetamine while Christy also is charged with probation violation and Dugan is charged with possession of a schedule II drug after “finished product” was found on his person, according to the agent. All three are scheduled to appear in Dickson Municipal Court Jan. 9.
