Omaha Man Sentenced to 235 Months for Fentanyl Distribution Conspiracy

United States Attorney Lesley A. Woods announced that Duane Walker, Jr., 29, of Omaha, Nebraska, was sentenced on March 12, 2026, in federal court in Omaha for conspiracy to distribute fentanyl. Chief United States District Court Judge Robert F. Rossiter, Jr., sentenced Walker Jr. to 235 months' imprisonment. There is no parole in the federal system. After Walker's release from prison, he will begin a five-year term of supervised release.

In November 2024, an FBI task force began investigating Walker as a fentanyl pill dealer in Omaha. In January 2025, law enforcement facilitated purchases of fentanyl pills from Walker three times. On February 3, 2025, investigators seized a USPS package destined for an address in Omaha, which was later determined to belong to Walker's grandmother. Investigators searched the package pursuant to a warrant and found almost 5,000 fentanyl pills inside. Walker was arrested on an unrelated warrant with a backpack containing $49,688 in cash.

A postal inspector determined the package was mailed from Seattle by co-defendant Alvin Mitchell. Postal records uncovered seven earlier packages that were mailed from Seattle to the same address in Omaha dating back to October 2024. Cell phone evidence secured pursuant to search warrants uncovered text message conversation between Walker and Mitchell about the packages. At sentencing, Walker was held responsible for a drug weight equivalent to approximately 29,000 fentanyl pills based off the weights of the earlier packages.

Mitchell, 38, of Seattle, pleaded guilty to conspiracy to distribute fentanyl. He faces a mandatory minimum of 15 years in prison at sentencing, scheduled for March 20, 2026. The cash seized from Walker will be forfeited to the United States as proceeds of drug trafficking.

This case was investigated by the Federal Bureau of Investigation, the Omaha Police Department, and the United States Postal Inspection Service.
