Shawnee Man Gets 20 Years for Manslaughter on Indian Land

George Edmond Walker, 39, of Shawnee, Oklahoma, is headed to federal prison for 20 years after being sentenced for the violent killing of Marshall Scott Dent on Sac and Fox Nation land. U.S. District Court Judge Vicki Miles-LaGrange handed down the 240-month sentence, marking the end of a twisted, years-long cover-up that began with a deadly altercation in December 2013.

On December 23, 2013, Walker met Dent near Shawnee, where what began as a confrontation escalated into murder. Court records reveal Walker killed Dent during the physical altercation on tribal land, then buried the body in an attempt to conceal the crime. When pressure mounted and Dent was reported missing the following day, Walker doubled down—digging up the remains and relocating them to another parcel of Sac and Fox land near Meeker, Oklahoma.

The FBI’s Evidence Response Team eventually recovered Dent’s body after investigators, following leads and intelligence, pinpointed the second burial site. The gruesome discovery confirmed what authorities had long suspected: Walker had gone to extreme lengths to hide the evidence of his violent act, but not far enough to outrun federal justice.

Walker was indicted on September 15, 2015, alongside Anne Marie Johnson, who later pleaded guilty on September 13, 2016, to misprision of a felony and awaits sentencing. On August 22, 2016, Walker entered a guilty plea to federal charges of voluntary manslaughter and unlawful removal of a dead body—admitting his role in both the killing and the elaborate concealment.

Judge Miles-LaGrange imposed the 240-month sentence to run consecutively to a separate 40-year state prison term Walker is already serving for assault and battery with a dangerous weapon in Pottawatomie County. The combined sentences ensure Walker will spend decades behind bars, a fact U.S. Attorney Mark A. Yancey emphasized: “This crime was extremely violent and consistent with this defendant’s long history of assaultive behavior.”

The investigation was a joint effort by the Sac and Fox Nation Police Department, Shawnee Police Department, Pottawatomie County Sheriff’s Office, Pottawatomie County District Attorney’s Office, and the Federal Bureau of Investigation. The case was prosecuted by Assistant U.S. Attorneys Arvo Q. Mikkanen, Ashley Altshuler, and Lori Hines—closing a grim chapter in Oklahoma’s criminal annals.
