A federal jury in the Northern District of Oklahoma has found a 27-year-old Jenks resident guilty of Assault Resulting in Serious Bodily Injury in Indian Country, following a violent incident that left his girlfriend with devastating leg fractures.

Jamon Charles Phetsacksith, a member of the Osage Nation, was convicted today after a trial that detailed a disturbing sequence of events from November 2024. According to evidence presented, including video surveillance, witness testimony, and medical records, the assault occurred after the couple -- who had been drinking-- began arguing at Phetsacksith's workplace late at night.

The victim attempted to de-escalate by leaving the vehicle and walking away, but surveillance footage showed

hetsacksith chasing her, preventing her departure, and pushing her. The jury also reviewed Phetsacksith's 911 call, in which he falsely claimed the victim had fallen down stairs and needed medical help. Once separated from him, she informed EMSA personnel that he had assaulted her.Body camera footage from Tulsa Police officers captured Phetsacksith admitting that the pair had been drinking, fought, and that "it got out of hand."

He further stated that he had "thrown her around."A trauma surgeon testified to the severity of the injuries: the victim's left ankle was fractured, and both her tibia and fibula were broken in half — resulting in breaks in three places overall.

She required surgery involving implanted rods and screws to repair the damage.Here are examples of X-ray images illustrating the type of severe fractures (tibia and fibula breaks)

These injuries highlight the serious and life-altering nature of the assault.Phetsacksith was indicted in May 2025 and has remained in custody since. He will continue to be held pending sentencing, which is scheduled at a later date.

The maximum penalty for this federal charge can include significant prison time, reflecting the gravity of violence in Indian Country. The case was investigated by the FBI (Oklahoma City and Tulsa divisions) and the Tulsa Police Department.
