Department of Justice TULSA, Okla. – Today, a federal jury convicted a Jenks man of Assault Resulting in Serious Bodily Injury in Indian Country after breaking his girlfriend’s shin and ankle during an argument.

In May 2025, Jamon Charles Phetsacksith, 27, was indicted for one count of Assault Resulting in Serious Bodily Injury in Indian Country. According to court documents and evidence presented at trial, in November 2024, Phetsacksith was drinking and hanging out with his girlfriend. Phetsacksith had a key to his work and drove his girlfriend to pick up his paycheck after hours. After arriving at Phetsacksith’s work, the two began arguing.

In an attempt to de-escalate the situation, the victim testified that she exited the vehicle and began walking away. Video surveillance shows Phetsacksith chasing after the victim and keeping her from leaving. He is then seen pushing the victim.

The jury heard the defendant’s 911 call, where he claimed that she had fallen down a flight of stairs and was in need of medical attention. When the victim was separated from Phetsacksith, she told EMSA personnel that he assaulted her. Tulsa Police officers responded to the scene and spoke with EMSA, the victim, and Phetsacksith. Body camera played for the jury showed Phetsacksith explaining that they were drunk, had a fight, and “it got out of hand.” He later told officers that he threw her around.

A trauma surgeon testified that the victim broke her leg in three places. Her left ankle was fractured, and her tibia and fibula bones were broken in half, requiring surgical rods and screws to be implanted.

Phetsacksith is a member of the Osage Nation, and he will continue to remain in custody until sentencing is scheduled at
a later date.

The FBI and Tulsa Police Department investigated the case. Assistant U.S. Attorneys Mallory Richard and Stacey Todd prosecuted the case.
