 Mario Serna from California was sentenced this week to more than 12 and a half years in federal prison after carrying heroin across state lines. The U.S. Department of Justice says Serna had the material in a false compartment of his bag, traveling by way of train through Bernalillo County when the U.S. Drug Enforcement Agency caught him with several kilograms of heroin. In a plea agreement, he admitted to planning on taking the drugs to North Carolina for distribution.
