Several UPS employees are among nearly a dozen people accused of shipping illegal drugs out of Tucson.
The Arizona Attorney General's Office says a grand jury indicted 11 people on 48 counts including money laundering, illegally conducting an enterprise and related charges. The defendants include four UPS employees.
The indictment is the culmination of a two-year investigation conducted by Tucson police, Homeland Security Investigations and the attorney general's office.
State prosecutors say the UPS workers and three others used closed business accounts to ship packages of contraband nationwide.
Representatives for UPS did not immediately return a message seeking comment.
