Duncan Man Sentenced to Serve 20 Years in Federal Prison Following Fatal Shooting in Indian Country

OKLAHOMA CITY – JESSE WAYNE JAMES KEENAN, 19, of Duncan, has been sentenced to serve a total of 240 months in federal prison for voluntary manslaughter and discharging a firearm during and in relation to a crime of violence, announced U.S. Attorney Robert J. Troester.

According to public record, on July 19, 2024, officers with the Duncan Police Department (DPD) responded to an apartment complex on a reported shooting. At the apartment, DPD located a male victim who had been shot. DPD attempted to provide medical care, but the victim died at the scene. Witnesses at the complex identified Keenan as the person who fired the weapon. Law enforcement located and arrested him a short time later. After speaking with Keenan, FBI agents learned Keenan went to the apartment complex after an argument between him and his girlfriend. Following his arrival, a fight ensued between him and the victim. During the altercation, Keenan shot the victim with a pistol and fled from the scene. The pistol was later recovered by the FBI.

On April 7, 2025, Keenan was charged by Superseding Information with one count of voluntary manslaughter and one count of discharging a firearm during and in relation to a crime of violence. Keenan pleaded guilty on May 1, 2025, and admitted that during a quarrel, he intentionally and unlawfully shot the victim, while intending to cause serious bodily injury, which resulted in the victim’s death.

At a sentencing hearing on December 12, 2025, U.S. District Judge Patrick R. Wyrick sentenced Keenan to serve 120 months in federal prison for each count, to run consecutively, followed by four years of supervised release, and ordered Keenan to pay $7,500 in restitution. In announcing his sentence, Judge Wyrick noted the nature and circumstances of the offense and the need to protect the public from future crimes of Keenan.

This case is in federal court because Keenan is a member of the Choctaw Nation, and the crime occurred within the boundaries of the Chickasaw Nation.

This case is the result of an investigation by the FBI Oklahoma City Field Office, the Oklahoma State Bureau of Investigation, and the Duncan Police Department. Assistant U.S. Attorneys Tiffany Edgmon and Bow Bottomly prosecuted the case.
