Prosecutors say McElmury, who lives in Cedaredge, Colorado, was pulled over on eastbound Interstate 80 near Lincoln on Jan. 21. A drug-sniffing dog taken to the scene alerted officers to the scent of drugs, and the pot was found in heat-sealed bags stuffed into four boxes, four duffel bags and a tote.
