Probably the most un-lucky drug dealer of all time, Shawn Langley of Vail, CO responded to an ad on Craigslist from Jason Mikesell, Teller County Sheriff, who was simply trying to sell an SUV trying to trade "black-market marijuana" of 'high quality' for the vehicle. Detectives picked up on the opportunity immediately and set up a buy/bust to see if the dealer was serious. Apparently, he was. Langley and an accomplice were arrested in possession of approximately four pounds of weed. See story from KDVR-Denver FOX.
