Osmar Lorenzo-Genchi, a 20-year-old from Omaha, was sentenced on March 18 in federal court for assaulting, resisting, or impeding an officer with the intent to commit another felony. United States District Judge Brian C. Buescher ordered Lorenzo-Genchi to serve 22 months in prison and pay $2,284.40 in restitution. After his release, he will be under supervised release for three years.
The case stems from an incident on June 10, 2025 at Glenn Valley Foods in Omaha during the execution of a civil search warrant by law enforcement. Agents from Homeland Security Investigations interviewed employees and verified their legal work status. Lorenzo-Genchi was identified as a U.S. citizen and released after his information was collected.
According to the United States Attorney’s Office, when Deputy United States Marshals attempted to leave the area later that day, several people—including Lorenzo-Genchi—blocked their vehicle by standing in the street. The situation escalated when Lorenzo-Genchi struck and damaged a law enforcement vehicle’s side mirror with his fist and bent its rear windshield wiper before spitting on one of the deputies. He then threw rocks at law enforcement vehicles as they departed, damaging seven vehicles including shattering a window of an occupied car.
Officers tried to apprehend him but were unable due to safety concerns caused by a growing crowd; he was later arrested on a federal warrant.
United States Attorney Lesley A. Woods said, “Any assault on federal law enforcement officers who are simply carrying out their official duties and following orders to keep our communities safe will result in federal charges. Deputies who serve in the United States Marshals Service like those who were targeted here are an invaluable part of the federal law enforcement community. They apprehend some of the nation’s most dangerous fugitives, and they enforce the federal sex offender registry. These assaults on their deputies cannot be tolerated because it jeopardizes their ability to carry out these critical public safety missions. Justice was done with this conviction and sentence.”
Homeland Security Investigations conducted the investigation into this case.
