Omaha Man Sentenced for Assaulting, Resisting, or Impeding Officer Involving the Intent to Commit Another Felony

United States Attorney Lesley A. Woods announced that Osmar Lorenzo-Genchi, 20, of Omaha, Nebraska, was sentenced on March 18, 2026, in federal court in Omaha for assaulting, resisting, or impeding officer involving the intent to commit another felony. United States District Judge Brian C. Buescher sentenced Lorenzo-Genchi to 22 months' imprisonment. There is no parole in the federal system. After Lorenzo-Genchi is released from prison, he will begin a 3-year term of supervised release. Lorenzo-Genchi was also ordered to pay $2,284.40 in restitution.

On June 10, 2025, law enforcement encountered Osmar Lorenzo-Genchi at Glenn Valley Foods in Omaha, while executing a civil search warrant. After accounting for all employees, Homeland Security Investigations special agents interviewed them and collected biometrics to verify their legal work status in the United States. Lorenzo-Genchi was identified as a U.S. citizen, his name logged, photograph taken, and he was escorted off the property and released.

Once all identifications were completed, a Deputy United States Marshal driving a law enforcement vehicle, accompanied by two others, attempted to leave the area eastbound on J Street in Omaha. Several members of the public, including Lorenzo-Genchi, obstructed the vehicle's path by standing in the street and moving in front of the vehicle as it tried to maneuver around them.

The Deputy Marshals stopped their vehicle and got out to clear pedestrians from the roadway. One Deputy Marshal pushed Lorenzo-Genchi to the edge, but he quickly returned to the road and struck the driver's side mirror of the law enforcement vehicle with his fist, damaging it. When the vehicle tried to leave, Lorenzo-Genchi grabbed the rear windshield wiper and bent it, rendering it unusable. A Deputy Marshal then pushed him away. In response, Lorenzo-Genchi turned and spat on the Deputy Marshal.

Lorenzo-Genchi walked west away from the Deputy Marshal and toward departing federal law enforcement. He started throwing rocks and debris at law enforcement vehicles, hitting at least seven in total. One rock shattered the rear passenger side window of an occupied vehicle. Officers exited their vehicles to apprehend him, but the increasing crowd of individuals made it unsafe to do so. Lorenzo-Genchi was later arrested on the federal warrant.

At the time of the assault, the federal law enforcement officers were doing what they were employed by the federal government to do.

U.S. Attorney Lesley 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."

This case was investigated by Homeland Security Investigations.
