A Detroit man who picked up a parcel packed with nearly a kilogram of powdered fentanyl is heading to federal prison for five years after a Tucson-based investigation followed the shipment from Arizona to Michigan and into an alleged local drug pipeline.
According to a press release from the U.S. Attorney's Office for the District of Arizona, 63-year-old Mark Craythorn Thompson of Detroit pleaded guilty to Conspiracy to Distribute Fentanyl. On June 25, U.S. District Judge Rosemary Márquez sentenced him in Tucson to 60 months in prison, followed by four years of supervised release. The office identified Assistant U.S. Attorney David Petermann as the prosecutor on the case, which is filed under number 23-CR-2465-TUC-RM.
As reported by KVOA, prosecutors said Thompson picked up a package in Detroit on September 28, 2023, that contained about 997.3 grams of powdered fentanyl after it was shipped from Arizona through the U.S. Mail. Authorities allege Thompson planned to deliver the drugs to contacts in the Detroit metro area, and officials say the case grew out of a broader mail-interdiction effort involving multiple agencies.
Homeland Security Task Force Handled The Case
The U.S. Attorney's Office said the prosecution was pursued under the Homeland Security Task Force, or HSTF, initiative, a federal effort that pulls together Homeland Security Investigations, the U.S. Postal Inspection Service, the DEA, the FBI and other partners to target cross-border trafficking groups. In this case, prosecutors said the Arizona-Tucson arm of HSTF coordinated investigative work, forensic analysis and postal reviews that led to the intercepted package and, ultimately, Thompson's conviction.
Mail Shipments And The Bigger Picture
Federal agencies have increasingly zeroed in on parcel-based drug trafficking because synthetic opioids can be moved in small, easily shipped quantities that are tough to spot in the mail. A December GAO report found that Mexican transnational criminal organizations obtain chemical precursors from abroad, produce synthetic opioids in clandestine labs, and often lean on parcel networks and e-commerce channels to push those drugs across the United States, a pattern that task forces like HSTF are now prioritizing.
Prosecutors said the Tucson case is one of several recent federal prosecutions aimed at choking off mail-based fentanyl supply lines into American cities. Court records show Thompson will serve his time in federal custody, followed by a four-year term of supervised release as part of his sentence.
