Six men and one woman have been charged in Charlotte with conspiring to distribute black-tar heroin, in a federal bust that netted about 6 pounds of the drug, according to a federal criminal complaint filed Monday.
Agents also seized cash, cell phones and two handguns during searches of five homes and two cars.
All seven suspects face federal charges of conspiracy and possession with intent to distribute at least one kilogram of cocaine.
The drug is a growing problem in Charlotte, which investigators say has become a hub for heroin distribution. Overdoses and deaths associated with the drug in the city more than tripled in 2009 compared to the year before, and the amount of heroin seized quadrupled.
A confidential informant told authorities that Rosario Delgadillo-Olivarez, 34, planned to meet a man Friday to give him heroin, an agent for the Drug Enforcement Administration said in the complaint.
