In brief: Federal courts sentenced 412 people under §2A1.4 in fiscal years 2016 to 2025. Of those, 384 (93%) received prison, with a median term of 37 months (3.1 years). The sentence was within the guideline range for 185 people (45%) and above it for 100 (24%).
This post uses the U.S. Sentencing Commission's records of 412 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.
Sentences Above the Range Were Common
Sentences above the guideline range were more common here than under several other guidelines. In all, 100 of 412 people (24%) were sentenced above the range. Within the range were 185 (45%).
Below the range at the government's request were 54 (13%), and below the range without such a request were 73 (18%). The guideline range is the one the Sentencing Guidelines produce for the case, so these figures show how the sentence compared with it, not how the range was built.
What §2A1.4 Covers
The Sentencing Guidelines Manual titles this section "Involuntary Manslaughter." The Sentencing Commission files the cases under the offense type Manslaughter.
The 412 people are those for whom §2A1.4 was the primary guideline, the one that set the offense level for the most serious count. The data covers only people who were convicted and sentenced.
Length of Prison Terms
The median prison term was 37 months among the 384 people sent to prison. A quarter received 60 months or more, and a quarter received 24 months or less. The terms are those imposed, not time served.
Another 23 people (6%) received probation only. A mandatory minimum prison term applied to 3 people, which is less than 1%.
Pleas and Trials
A guilty plea was entered by 386 people (94%), and 26 were convicted after a trial. Among those who pleaded guilty, 83% had a written plea agreement, and 17% were straight pleas.
The median prison term was 37 months after a guilty plea and 51 months after a trial. The trial median rests on 26 people.
Supervised Release, Fines, and Restitution
Supervised release after prison was ordered for 377 people (92%), with a median term of 36 months. Restitution was ordered for 221 people (54%), and a fine for 9 (2%).
In this group 65% were in the lowest criminal history category I, and 2% were in the highest, VI.
Little Change Across the Decade
The median prison term was 37 months in fiscal years 2016 to 2019 and 37 months in fiscal years 2020 to 2025. The earlier period had 169 people, and the later one had 243.
Single years varied more. The yearly table shows a median of 18 months in 2021 and 46 months in 2025, with 26 people sentenced in 2020 and 60 in 2024. The records cannot say why a year differed.
| Fiscal year | People sentenced | Median prison | Pleaded guilty |
|---|---|---|---|
| 2016 | 41 | 36 months | 95% |
| 2017 | 43 | 37 months | 98% |
| 2018 | 38 | 37 months | 97% |
| 2019 | 47 | 37 months | 94% |
| 2020 | 26 | 38 months | 88% |
| 2021 | 28 | 18 months | 96% |
| 2022 | 39 | 41 months | 97% |
| 2023 | 42 | 37 months | 90% |
| 2024 | 60 | 32 months | 87% |
| 2025 | 48 | 46 months | 96% |
Court-Martial Crosswalk and Limits
This guideline is part of the approved pairing with Article 119 of the UCMJ, and the comparison posts cover that pairing. This post reports only the federal side. Acquittals and dismissals are not in the Sentencing Commission data, so it cannot show how many charges ended without a conviction.
How We Counted
Everyone sentenced in federal court in fiscal years 2016 to 2025 whose primary sentencing guideline was §2A1.4 (412), from the U.S. Sentencing Commission's individual data files. The primary guideline is the one that set the offense level for the most serious count.
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.
