Federal officials have broken up a major Mexican-supplied drug- and weapons-trafficking ring that was caught selling large amounts of drugs, guns, and grenades and smuggling them to an Iraqi community in Detroit. Police in El Cajon, Calif., say they’ve made more than 60 arrests in the bust, and the feds have seized 18 pounds of methamphetamine, narcotics, cocaine, and other drugs, including 3,500 pounds of marijuana. They also recovered $630,000 in cash and more than 30 guns, including assault rifles. Officials believe the Detroit Iraqis were planning to distribute much of the marijuana and that the firearms were going to be sold in local markets. The ring was supplied by Sinaloa, Mexico’s biggest and most powerful drug cartel.
