OKLAHOMA CITY — An Alva man with a lengthy criminal history, including prior domestic violence convictions, has been sentenced to six years in federal prison for illegally possessing a firearm as a convicted felon.

Michael Dewayne Hebert, 40, was sentenced on June 5, 2026, to 72 months in federal prison followed by three years of supervised release, according to the U.S. Attorney's Office for the Western District of Oklahoma.

Court records show the case stemmed from a domestic violence incident on June 26, 2025, at a residence in Alva.

According to investigators, the victim learned that Hebert had taken possession of her firearm and stored it inside a drawer in the home. When she asked him about the weapon, Hebert went into another room and slammed the door.

Authorities said Hebert then called for assistance, claiming the door was stuck. When the victim helped open the door, Hebert allegedly grabbed her by the throat, strangled her and threatened to kill her.

Responding officers with the Alva Police Department observed injuries to the victim's neck and reviewed surveillance footage that reportedly showed Hebert placing his hand around the victim's throat.

A federal grand jury indicted Hebert on Sept. 2, 2025, on one count of Felon in Possession of a Firearm.

Hebert pleaded guilty on Nov. 14, 2025, admitting that he knowingly possessed a firearm despite being prohibited from doing so because of prior felony convictions.

During sentencing, U.S. District Judge Timothy D. DeGiusti cited Hebert's extensive criminal history and the danger he poses to the public.

Public records indicate Hebert has multiple felony convictions in Louisiana, including several domestic abuse and assault-related offenses.

The investigation was conducted by the FBI Oklahoma City Field Office and the Alva Police Department.

Assistant U.S. Attorney Mary E. Walters prosecuted the case.
