A Chicopee man who police said used McDonald's Happy Meal toy bags to conceal heroin deliveries has been indicted by a Hampden County grand jury. Narcotics detectives arrested Giovannie Luna on April 15 after he allegedly attempted to make a drug sale in Springfield. Police seized more than 9,500 packets of heroin in the arrest in addition to cash and a loaded .22-caliber handgun recently reported stolen in Westfield, police officials said. The Springfield Republican reported that Luna, 31, was initially due in Springfield District Court before he was indicted and had his case transferred to Superior Court. He is expected to be arraigned in Superior Court next week.
