The charges carry varying maximum penalties, including up to life in prison for some of the defendants.

          Further details of the investigation are available in the criminal complaints filed in United States v. Luis Alberto Cruz, No. 1:20-mj-00145 and United States v. Carlos Martinez, No. 1:20-mj-179.

          The charges are the result of a combined federal, state, and local investigation conducted by the Drug Enforcement Administration, U.S. Customs and Border Protection, U.S. Postal Inspection Service, Michigan Department of Corrections, the Grand Traverse County Sheriff’s Office, and the Michigan State Police and its sponsored drug trafficking task forces: the West Michigan Enforcement Team, the Southwest Enforcement Team, and the Traverse Narcotics Team.

          The charges in the superseding indictment are merely accusations and are not evidence of guilt. The defendants are presumed innocent unless and until proven guilty in a court of law. The government has the burden of proving guilt beyond a reasonable doubt.
