Shawnee Woman Sentenced To Serve 14 Months in Prison for Covering Up Manslaughter on Indian Land

For Immediate Release
U.S. Attorney's Office, Western District of Oklahoma

Oklahoma City, Oklahoma Anne Marie Johnson, 38, of Shawnee, Oklahoma, was sentenced yesterday by United States District Court Judge Vicki Miles-LaGrange to serve 14 months in federal prison for misprision of a felony for her role in the manslaughter of Marshall Scott Dent committed on Indian land, announced Mark A. Yancey, United States Attorney for the Western District of Oklahoma.


According to court records and information from court proceedings, George Edmond Walker, 39, of Shawnee, and Marshall Scott Dent met on December 23, 2013. During an altercation between the two men, Walker killed Dent on Sac and Fox Nation land near Shawnee, Oklahoma. Dent was reported missing on December 24, 2013. Investigators later determined that Walker buried Dent’s body on Sac and Fox land, where Johnson lived, near Shawnee in an attempt to hide the crime. Later, Walker dug up the body and moved it to another parcel of Sac and Fox land near Meeker, Oklahoma, where he buried Dent’s body again. During the investigation, law enforcement obtained information on the location of the body, where it was later recovered by the FBI’s evidence response team.


On September 13, 2016, Johnson pled guilty to misprision of a felony because she had knowledge about the killing but failed to report it to law enforcement. Yesterday, Johnson was sentenced to serve 14 months in federal prison, to be followed by 12 months of supervised release.


On August 22, 2016, Walker pled guilty to voluntary manslaughter and unlawful removal of a dead body. Last month, Judge Miles-LaGrange sentenced Walker to serve 240 months in federal prison to be followed by three years of supervised release. That sentence was ordered to be served consecutive to a 40-year sentence Walker is currently serving for his conviction of assault and battery with a dangerous weapon in Pottawatomie County.


This case was investigated 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.
