All suspects are presumed innocent until proven guilty in a court of law.
(Fremont County, WY) – The sentencing hearing for Fremont County man Damion Loneman Jr. has been set for April 2, according to updated federal court filings following his January 6 change of plea hearing in Casper.
Loneman was charged with Involuntary Manslaughter, as well as two Assault Resulting in Serious Bodily Injury charges (one of which against a minor), for reported events occurring in November of 2024 within the confines of the Wind River Reservation.
Both the original and superseding indictments filed state that Loneman “did unlawfully kill (victim’s name not shared) without malice but with wanton and reckless disregard for human life, while engaging in the commission of unlawful acts not amounting to a felony, that is, driving a motor vehicle under the influence of alcohol.”
Loneman initially pled “not guilty” to the charges at his November 25 Initial Appearance hearing, and a Jury Trial was set for January 26, 2026. However, a nonpublic plea agreement was later filed on Loneman’s behalf on December 22, and the January 6 change-of-plea hearing was set.
Loneman pled “guilty” to the Involuntary Manslaughter at the change-of-plea hearing, resulting in the April 4 sentencing hearing.
The maximum sentence for the Involuntary Manslaughter charge is 6 years imprisonment, a $250,000 fine, and three years of supervised release.
