OKLAHOMA CITY – MICHAEL DEWAYNE HEBERT, 40, of Alva, has been sentenced to serve 72 months in federal prison for illegal possession of a firearm after a previous felony conviction, announced U.S. Attorney Robert J. Troester. According to court records, on June 26, 2025, officers with the Alva Police Department responded to a residence following a reported domestic violence incident. Shortly before the assault, the victim learned that Hebert had taken possession of the victim’s firearm and stored it in a drawer inside the residence. The victim asked Herbert about the firearm's location, and he went into a room and slammed the door. He then called for help, claiming the door was jammed. When the victim assisted him in opening the door, Hebert grabbed the victim by the throat and strangled and threatened to kill her. Officers observed injuries to the victim’s neck and reviewed surveillance footage from the residence that showed Hebert placing his hand around the victim’s throat.On September 2, 2025, a federal grand jury indicted Hebert for being a felon in possession of a firearm. Hebert pleaded guilty on November 14, 2025, and admitted he knowingly possessed a firearm despite his prior felony convictions.At a sentencing hearing on June 5, 2026, U.S. District Judge Timothy D. DeGiusti sentenced Hebert to serve 72 months in federal prison, followed by three years of supervised release. In announcing his sentence, Judge DeGiusti noted Hebert’s extensive criminal history, including domestic violence convictions, as well as the danger he poses to the public. Public records reflect that Hebert has multiple prior felony convictions in Louisiana, including several convictions for domestic abuse and assault-related offenses.This case is the result of an investigation by the FBI Oklahoma City Field Office and the Alva Police Department. Assistant U.S. Attorney Mary E. Walters prosecuted the case. This case is part of Operation Take Back America (OTBA), a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs), and protect our communities from the perpetrators of violent crime.
