(Rochester, MN) — A Rochester man is facing drug charges after agreeing to sell a bottle of liquid codeine to a police investigator for 300 dollars. The criminal complaint says the officer answered an online ad from 20-year-old Thoung Duy Nguyen, which led to a search of his home and vehicle on Thursday. Authorities say they seized more than 12 hundred grams of liquid codeine, 71 grams of psychedelic mushrooms, a jar of marijuana, and nearly 33 hundred dollars. Nguyen also admitted that he had a ghost gun. He’s facing charges of first-degree drug sales and second-degree drug possession.
