In brief: 35 people were sentenced for manslaughter offenses in the Northern District of Oklahoma from fiscal year 2017 to 2025. 33 of them (94%) received a prison term, and the median was 78 months (6.5 years). For manslaughter cases in all 94 federal districts, the median prison term was 63 months.
This post uses the U.S. Sentencing Commission's records of 35 people sentenced in federal court in fiscal years 2016 to 2025. Acquittals and dismissals come from a second source, the Federal Judicial Center's records of 753,808 federal defendants whose cases ended in fiscal years 2016 to 2025. It is part of the Federal Prosecution Analysis series, which builds on Military Moves Toward Sentencing Guidelines to Mirror the Federal System. How the numbers were built: How the Federal Comparison Data Was Built.
How Long the Prison Terms Were
Among the 33 people sent to prison, the median prison term was 78 months, which is 6.5 years. A quarter received 87 months or more, and a quarter received 37 months or less. 1 person (3%) received probation only.
The median for all districts was 63 months, and 96% of people in the offense type were sent to prison. The median in this district was higher, and the share sent to prison was about the same.
The median for all offenses in the Northern District of Oklahoma was 37 months.
Voluntary and Involuntary Manslaughter
"Manslaughter" is the U.S. Sentencing Commission's offense type for these cases. The primary guideline was §2A1.3 (Voluntary Manslaughter) for 18 people and §2A1.4 (Involuntary Manslaughter) for 16 people. §2X3.1 (Accessory After the Fact) applied to 1 person.
The main guidelines cover different conduct, so the overall median combines different kinds of cases. The sheet does not give a separate median for each guideline.
Manslaughter cases were 1% of the 3,400 people sentenced in the district in fiscal years 2016 to 2025.
Sentences Above the Guideline Range
The guideline range is the range the court calculates under the Sentencing Guidelines. 49% of the 35 people (17) were sentenced within it, which is more than the 45% for all districts and for the whole district.
29% (10) were sentenced above the range. 20% (7) were below the range at the government's request, and 3% (1) were below it without a government request.
A mandatory minimum prison term applied to 1 of the 34 people with that information recorded (3%).
Guilty Pleas
34 of the 35 people (97%) pleaded guilty, and 1 was convicted after a trial. The rate for all districts was 93%.
The median prison term after a guilty plea was 70.5 months. The median after the one trial was 87 months. A single person does not allow a comparison.
79% of guilty pleas had a written plea agreement, and 21% were straight pleas with no agreement.
Supervision and Criminal History
33 people (94%) were ordered to serve supervised release after prison, with a median term of 36 months. A fine was ordered for 2 people (6%), and restitution for 4 (11%).
63% were in the lowest criminal history category, category I. 0% were in the highest, category VI.
Year-by-Year Counts
Fiscal years run from October 1 to the end of September. Fiscal years 2016 to 2019 have 1 person, and fiscal years 2020 to 2025 have 34 people.
The most people in one year was 10, in 2024. The yearly medians in the table go from 37 months in 2023 to 84 months in 2025. With 3 to 10 people in a year, these are small groups, and they do not show a trend.
| Fiscal year | People sentenced | Median prison | Pleaded guilty |
|---|---|---|---|
| 2017 | 1 | 92 months | 1 of 1 |
| 2021 | 4 | 62 months | 4 of 4 |
| 2022 | 8 | 61.5 months | 7 of 8 |
| 2023 | 3 | 37 months | 3 of 3 |
| 2024 | 10 | 81 months | 100% |
| 2025 | 9 | 84 months | 9 of 9 |
What Cannot Be Learned From the Records
The Commission counts only people who were convicted and sentenced. Acquittals and dismissals are not in the data. Prison terms are the terms imposed, not time served.
The records do not describe the circumstances of any case, so they cannot explain why 10 people were sentenced above the guideline range.
How We Counted
Everyone sentenced in federal court in the Northern District of Oklahoma (U.S. Sentencing Commission district label "Oklahoma North") in fiscal years 2016 to 2025 whose offense type was "Manslaughter" (35). Offense types are the Commission's OFFGUIDE categories.
Federal fiscal years run from October 1 to September 30. No person, judge, or lawyer is identified in any of these records.
What to Keep in Mind
No parole in federal prison; credit for good conduct. Federal prison has no parole for crimes committed on or after November 1, 1987. A federal prisoner can earn up to 54 days of good conduct credit for each year of the sentence the judge imposed, which is about 15%. Some federal prisoners can also earn First Step Act time credits, but many offenses make a person ineligible. The numbers in this post are the sentences judges imposed, not the time people actually served.
Federal supervised release. Most federal prison sentences are followed by a term of supervised release that the judge sets as part of the sentence. A person who violates it can be sent back to prison. A court-martial cannot sentence anyone to supervision after release. Military parole and mandatory supervised release are decided later by a board, not by the judge at trial.
Who decides the sentence, and under what rules. Federal judges sentence every federal case. They must calculate the Sentencing Guidelines range, which is advisory, and must impose any mandatory minimum the statute requires unless an exception applies. In courts-martial, the accused could choose sentencing by members until the rules changed. For cases in which every guilty finding is for an offense committed after December 27, 2023, a military judge sentences alone, within sentencing parameters. Courts-martial tried in 2024 and later include both old-rule and new-rule cases, and the data cannot tell them apart.
Time periods. Federal numbers are by federal fiscal year (October 1 to September 30), based on the sentencing date. The military numbers are by trial date. Neither source has the date of the offense, so a change in law shows up in either data set gradually.
How life sentences and "time served" are counted. In the federal numbers, a life sentence is counted as 470 months, and any other sentence longer than 470 months is counted as just under 470 months. A sentence of "time served" is counted as one day (0.03 months). Averages are affected by these rules; medians much less.
Mandatory minimum sentences. Many federal statutes on drugs, images of child exploitation, child sex abuse, and firearms carry mandatory minimum prison terms. The UCMJ has mandatory minimums only for a few offenses (a dishonorable discharge or dismissal for rape and sexual assault, and life for premeditated murder). Federal sentences for these offenses are partly set by Congress, not by the judge.
