Tyler Thompson has been sentenced to 64 months in federal prison for a March 2024 crash in Chouteau that killed his significant other, Nancy Moore. After serving that term, he will spend three years on supervised release. Thompson previously pleaded guilty to involuntary manslaughter in Indian Country.
Investigators told reporters that Thompson had used methamphetamine and marijuana earlier the same day and was driving without a valid license, according to KOKH. That reporting states a hospital toxicology screen later showed methamphetamine, amphetamine and multiple THC metabolites in his blood. Investigators said Thompson ran a red light and hit the back of a tractor-trailer, and that Moore died from blunt-force trauma.
Records, Family Name Nancy Louise Moore as Victim
Family members and public records identify the passenger who died as 52-year-old Nancy Louise Moore. An obituary posted by Mallett Funeral Home says she died on March 26, 2024, and lists Thompson as her significant other. The funeral notice notes that services took place in early April.
Court Records Detail Repeated Drug Use While Awaiting Sentence
Court filings cited in local coverage show Thompson pleaded guilty to involuntary manslaughter in Indian Country and received a 64-month prison sentence followed by three years of supervised release, according to KOKH. Those records indicate he tested positive for marijuana eight times and for amphetamines seven times while awaiting sentencing, and that he skipped required drug tests.
Why "Indian Country" Changes Who Prosecutes
The phrase "in Indian Country" signals that federal authorities have jurisdiction under statutes and case law governing crimes on lands defined as Indian country. Courts in the 10th Circuit have described how 18 U.S.C. §§ 1151 and 1153 work in these prosecutions. For more on that jurisdictional framework and how federal charges in such cases proceed, see a Tenth Circuit opinion summarized on Justia.
Thompson’s guilty plea and sentence close a federal case that began with the March 2024 wreck, with court documents and local reporting outlining what investigators say happened and how the punishment was set. Coverage to date has focused on the crash details, toxicology findings and plea; early reports did not include public statements from Moore’s family or from attorneys involved in the case.
