Man Sentenced for Drug Conspiracy

For Immediate Release
U.S. Attorney's Office, District of Nebraska

Acting United States Attorney Susan Lehr announced that Oscar Ulises Quiroz Ayon, 32 of Mexico was sentenced January 19, 2024, in federal court in Omaha, Nebraska, for his participation in a methamphetamine and fentanyl drug conspiracy. Chief United States District Judge Robert F. Rossiter, Jr. sentenced Ayon to 33 months’ imprisonment.  There is no parole in the federal system.  After Ayon’s release from prison, he will begin a 2-year term of supervised release. 

Beginning in August 2021 and continuing to November 4, 2021, Ayon agreed with others to distribute and possess with intent to distribute over 50 grams of meth actual and over 100 grams of fentanyl analogue.

Throughout the day on November 4, 2021, agents conducted surveillance on Ayon’s codefendant Colleen Wiand. That afternoon, Wiand drove to the Supermercado, located at 3548 Q Street, in Omaha, where she parked.

Shortly after, Ayon arrived in the parking lot, parking next to Wiand..  Ayon placed an item in Wiand’s car then both cars departed.  Omaha Police Department officers conducted a traffic stop in Wiand’s car and recovered a box containing approximately 13.4 pounds of pills marked ‘M-30,’ suspected fentanyl in pill form.  Wiand was then taken into custody.

Officers conducted a traffic stop on Ayon near 30th and Chandler Streets in Omaha. After receiving his Miranda warnings, Ayon admitted that approximately two months ago he arrived in Omaha from Sinaloa, Mexico for the specific purpose of receiving controlled substances.

The morning of November 4, 2021, Ayon admitted that he received a phone call from someone in Mexico who instructed him to go to the Casey’s located at 72nd and Grover Streets, in Omaha, to meet a white male who gave him a TV box. The same person in Mexico then told Ayon to meet a woman at the Supermercado located at 36th and Q and deliver the TV box.

The following codefendants have all previously pled guilty to the drug conspiracy and been sentenced:  Wiand, Mayra Rendon, Darbelio Lorenzo-Genchi, Iris Gallardo-Salado, Samantha Cawyer, Giovana Cisneros and Emidio Becerra.

This operation is part of an Organized Crime Drug Enforcement Task Forces (OCDETF) investigation. OCDETF identifies, disrupts, and dismantles the highest-level drug traffickers, money launderers, gangs, and

transnational criminal organizations that threaten the United States by using a prosecutor-led, intelligence-driven, multi-agency approach that leverages the strengths of federal, state, and local law enforcement agencies against criminal networks.

This case was investigated by the Omaha Police Department and Drug Enforcement Administration.
