Moise Mendez appears in Boulder County court on March 28, 2014 in Boulder, Colo. Mendez, along with Russell Britton and Daniel Ortiz are charged with felony first-degree murder, robbery and aggravated motor-vehicle theft in the death of 25-year-old Nathaniel Tallman. Tallman was shot dead trying to sell marijuana the old-fashioned, illegal way. While no one expected the state's first-in-the-nation recreational sales would eliminate the need for dangerous underground sales overnight, the violence has raised concerns among police, prosecutors and pot advocates that a black market for marijuana is alive and well in Colorado.
