Tucson, AZ - Mark Craythorn Thompson of Detroit, Michigan, was sentenced on June 25, by United States District Judge Rosemary Márquez to 60 months in prison, followed by four years of supervised release. Thompson previously pleaded guilty to Conspiracy to Distribute Fentanyl.

As part of this conspiracy, Thompson picked up a package in Detroit, Michigan on Sept. 28, 2023, that contained 997.3 grams of powdered fentanyl. The package had been shipped to Michigan from Arizona in the U.S. Mail, and Thompson intended to deliver the fentanyl to individuals in the Detroit metro area.
