A machete-wielding Michael Eugene Spears, 59, of Claremore, was sentenced Tuesday to 300 months in federal prison for the brutal second-degree murder of Mark McKinney in November 2017. The sentencing, handed down by U.S. District Judge Gregory K. Frizzell, caps a years-long legal odyssey that shifted from state court to federal jurisdiction after the McGirt v. Oklahoma decision reshaped criminal prosecutions in tribal territory.
The killing unfolded inside a trailer owned by Spears’ sister after a heated disagreement between the two men on Nov. 18, 2017. Armed with a 16-inch machete, Spears launched a savage assault, stabbing and bludgeoning McKinney until his face was unrecognizable. Prosecutors detailed how Spears then stole McKinney’s phone and the few dollars in his pocket before leaving the body on the trailer floor and drinking for hours, attempting to wash away the aftermath with alcohol.
Following the attack, Spears confessed to a relative, asking to borrow a truck to haul McKinney’s body to a remote lake for disposal. That relative tipped off law enforcement the next morning, leading to the recovery of the victim’s body from the trailer. Evidence gathered by the Claremore Police Department and FBI painted a damning picture of premeditated violence and cold-hearted concealment.
At sentencing, prosecutors Thomas E. Duncombe and Justin G. Bish argued for the full 30 years, citing the extreme brutality and Spears’ lack of remorse. “The defendant’s murderous act and attempted cover-up earned him a 25-year federal prison sentence,” said U.S. Attorney Clint Johnson. The defense countered with a 15-year request, pointing to Spears’ history of alcoholism, cognitive decline, and a troubled upbringing, even suggesting self-defense—claims prosecutors dismissed as baseless given the crime scene evidence.
FBI Oklahoma City Special Agent in Charge Edward J. Gray emphasized the collaborative effort that brought Spears to justice: “Today’s sentencing brings to an end a tragic story of cold-blooded murder and an attempted cover-up by a merciless and violent criminal.” He credited the tenacity of the Claremore Police Department, FBI agents, and federal prosecutors for ensuring accountability.
Spear’s original first-degree murder conviction in Rogers County District Court was vacated after the U.S. Supreme Court’s McGirt ruling confirmed much of eastern Oklahoma, including the Cherokee Nation reservation, as tribal land. Because Spears is a tribal citizen and the crime occurred within reservation boundaries, federal jurisdiction applied. Second-degree murder under federal law closely mirrored the state charge, allowing the U.S. Attorney’s Office to secure justice where state courts could not. Spears will serve 300 months in federal prison, followed by five years of supervised release.
