Choteau Man Sentenced for Driving Impaired and Causing Fatal Car Wreck

TULSA, Okla. - A Choteau man was sentenced for Involuntary Manslaughter in Indian Country after driving impaired and causing a fatal car wreck, announced U.S. Attorney Clint Johnson.

U.S. District Judge Gregory K. Frizzell sentenced Tyler Ray Thompson, 29, to 64 months' imprisonment, followed by three years of supervised release.

The investigation revealed that in March 2024, Thompson began his day by consuming methamphetamine and marijuana. Thompson had never held a valid driver's license and told investigators that he usually drove only in neighborhoods. On the date of the incident, he claims that his significant other, Nancy Moore, drove them to her dentist's appointment but could not drive afterward because she was under anesthesia. After Thompson purchased more marijuana, he attempted to drive on a busy highway. On the drive home, he failed to stop at a red light and struck the rear end of a tractor-trailer while driving at approximately 57 miles per hour. Nancy Moore died from blunt force trauma.

The toxicology report confirmed that Thompson had methamphetamine, amphetamine, THC, hydroxy-THC, and THCA in his blood when he was treated at the hospital shortly after the crash.

Thompson is a citizen of the Muskogee Creek Nation. He was previously released on bond but was taken into custody after violating the terms of his pretrial release in July. Court documents show that after pleading guilty and while awaiting sentencing for this offense, he tested positive for marijuana eight times, for amphetamines seven times, failed to appear for required drug tests, and missed six scheduled mental-health treatment appointments. Thompson will remain in custody, pending transfer to the U.S. Bureau of Prisons.

The FBI and the Pryor Police Department investigated the case with assistance from the Oklahoma State Bureau of Investigations and the Office of the Chief Medical Examiner. Assistant U.S. Attorney Scott Dunn prosecuted the case.
