How Many Years for Second Degree Murder? Sentences by State (2026)

Last updated: March 23, 2026

Second degree murder is one of the most serious criminal charges in the United States, but the sentence it carries varies enormously depending on where the crime occurs. A conviction can mean as few as 4 years in prison in Illinois or mandatory life without parole in Louisiana and Pennsylvania.

This guide provides a complete breakdown of second degree murder sentences in every state, the federal system, and the factors that push sentences higher or lower. If you need background on what the charge actually means, see our full guide on what is second degree murder.

Federal Second Degree Murder Sentencing

Under 18 U.S.C. § 1111, any murder that does not meet the criteria for first degree murder is classified as second degree murder. The federal statute defines murder as "the unlawful killing of a human being with malice aforethought."

Statutory Penalty

The federal penalty for second degree murder is imprisonment for any term of years or for life. There is no statutory mandatory minimum at the federal level, giving judges significant discretion.

Federal Sentencing Guidelines

The U.S. Sentencing Commission guidelines (USSG §2A1.2) set a base offense level of 38 for second degree murder. Using the 2025 sentencing table, this translates to:

Criminal History Category	Recommended Range
Category I (first offender)	235–293 months (19.5–24.4 years)
Category II	262–327 months (21.8–27.3 years)
Category III	292–365 months (24.3–30.4 years)
Category IV	324–405 months (27–33.8 years)
Category V	360 months–life (30 years–life)
Category VI	360 months–life (30 years–life)

These are guidelines, not mandatory. Judges can depart upward or downward based on the circumstances of the case.

States Without Traditional "Second Degree Murder"

Several states do not use the first/second degree classification for murder:

• Texas uses "capital murder," "murder," "manslaughter," and "criminally negligent homicide" instead of numbered degrees
• Alabama has a single "murder" charge (Class A felony, 10–99 years or life)
• Kentucky uses "murder" and "manslaughter" with its own degree system
• Connecticut has a single "murder" statute with no degree distinctions
• Georgia reserves second-degree murder only for deaths from child cruelty; primary charges are "malice murder" and "felony murder"

For a complete comparison of how states classify homicide offenses, see our guide to murder laws in the United States.

Factors That Increase Second Degree Murder Sentences

Courts consider multiple aggravating factors that can push sentences well above the standard range.

Firearm Enhancements

Firearm use during a murder dramatically increases the sentence in most states:

State	Enhancement	Effect
California	PC § 12022.53	+10 years (use), +20 years (discharge), +25-to-life (death)
Florida	10-20-Life Law	Mandatory 25 years to life with firearm
Federal	USSG §2A1.2	Included in base offense level

Other Aggravating Factors

• Prior criminal history — Repeat offenders face enhanced sentences. California's three strikes law counts second-degree murder as both a "serious" and "violent" felony strike.

• Victim was a law enforcement officer — California imposes 25 years to life. New Jersey imposes life without parole.

• Victim was a child — Ohio increases the sentence to 30 years to life for victims under 13 with sexual motivation. Alaska increases to 20–99 years for victims under 16. Arizona imposes LWOP for child victims under 15.

• Victim was elderly or disabled — Treated as an aggravating factor in sentencing in many jurisdictions.

• Extreme cruelty — Courts may depart upward from guidelines when the crime involved unusual brutality.

• Multiple victims — Sentences typically run consecutively rather than concurrently.

Factors That Decrease Second Degree Murder Sentences

Mitigating factors can significantly reduce sentences below the standard range.

Heat of Passion / Provocation

Several states treat heat-of-passion killings as a mitigating circumstance that reduces the charge or sentence:

• Colorado reduces the charge from a Class 2 felony (16–48 years) to a Class 3 felony (4–12 years)
• Illinois treats second degree murder itself as the mitigated form of first degree murder, carrying just 4–20 years
• Texas reduces the penalty from a first-degree felony (5–99 years) to a second-degree felony (2–20 years) when "sudden passion" is proven

Other Mitigating Factors

• No prior criminal history — First-time offenders receive significantly lower sentences. Minnesota's guidelines recommend just 12.5 years for first offenders.

• Mental illness or emotional disturbance — New York and North Dakota explicitly recognize "extreme emotional disturbance" as reducing the charge.

• Defendant's age — Youth is a constitutional mitigating factor per Supreme Court precedent.

• Cooperation with authorities — Substantial assistance can reduce sentences.

• Substance abuse at the time of the offense — Courts may consider this in determining culpability.

How Second Degree Murder Compares to Other Charges

Understanding the differences between murder, homicide, and manslaughter is critical, because the charge determines the sentence range. For a detailed breakdown of murder classifications, see our guide to first, second, and third degree murder.

Charge	Typical Sentence	Key Distinction
First Degree Murder	25 years to life, LWOP, or death	Premeditated and deliberate
Second Degree Murder	10–40+ years or life	Intentional but not premeditated, or extreme recklessness
Third Degree Murder (FL, PA, MN only)	10–40 years	Depraved-heart or unintentional during felony
Voluntary Manslaughter	3–15 years	Heat of passion with adequate provocation
Involuntary Manslaughter	2–10 years	Unintentional killing through criminal negligence

Only three states — Florida, Minnesota, and Pennsylvania — recognize a separate third degree murder charge. In most states, conduct that might be "third degree" elsewhere falls under second degree murder or manslaughter.

Recent Notable Cases and Sentences

Derek Chauvin — Minnesota (2021)

Former Minneapolis police officer Derek Chauvin was convicted of second-degree unintentional murder for the death of George Floyd. The court found four aggravating factors — including abuse of a position of trust and particular cruelty — and sentenced Chauvin to 22.5 years, nearly double Minnesota's guideline recommendation of 12.5 years.

Chauvin later pleaded guilty to federal civil rights charges and received a concurrent sentence of 21 years.

Karen Read — Massachusetts (2024–2025)

Karen Read was charged with second-degree murder in the death of Boston police officer John O'Keefe. Her first trial ended in a mistrial due to a hung jury in 2024. Her second trial in June 2025 resulted in acquittal on both murder and manslaughter charges. She was convicted only of DUI.

The case drew national attention for questions about police involvement and evidence handling, illustrating how second-degree murder charges can be difficult to prove.

Colin Gray — Georgia (2025–2026)

Colin Gray became the first parent in Georgia history convicted of murder for the actions of their child, in connection with the 2024 Apalachee High School shooting. He faced 27 counts including second-degree murder and manslaughter.

Cecil County Shooting — Maryland (2025)

A Delaware man received 180 years after conviction on 30 counts including two counts of second-degree murder for a 2024 shooting that killed two people and wounded two others, demonstrating how multiple counts and consecutive sentencing can result in sentences far exceeding any single charge's maximum.

How Long Do People Actually Serve?

The sentence imposed is not the same as the time actually served. According to the Bureau of Justice Statistics, state prisoners released in 2018 served an average of 58% of their imposed sentence for murder convictions.

The national average time served before initial release for all murder types is approximately 15 years. However, this varies enormously:

• A person sentenced to 15-to-life in California may serve 15–20 years before parole
• A person sentenced to mandatory life in Louisiana will never be released
• A person sentenced to 4–20 years in Illinois may serve less than 4 years with good-time credits

The Council on Criminal Justice reports that the United States imposes the longest average sentences for homicide among nations, at 40.6 years on average.

Murder Conviction Statistics

According to BJS data:

• Murder defendants are much more likely to go to trial (44%) than defendants charged with other violent felonies (6%)
• 88% of violent felons overall are convicted through guilty plea, but murder cases show significantly higher trial rates
• Murder accounts for approximately 0.6% of all felony convictions

Juvenile Sentencing for Second Degree Murder

Juvenile sentencing for murder has undergone dramatic changes following a series of Supreme Court decisions.

Key Supreme Court Rulings

Miller v. Alabama (2012) — The Court held that mandatory life-without-parole sentences for juveniles convicted of homicide violate the Eighth Amendment. Sentencing courts must consider a child's "diminished culpability and heightened capacity for change."

Source: Miller v. Alabama — Cornell Law

Montgomery v. Louisiana (2016) — The Court ruled that Miller applies retroactively, requiring resentencing for all juveniles previously given mandatory LWOP sentences.

Source: Montgomery v. Louisiana — Cornell Law

Jones v. Mississippi (2021) — The Court scaled back Miller's protections in a 6-3 decision. Judges are not required to find that a juvenile is "permanently incorrigible" before imposing LWOP. The only requirement is that the sentence be discretionary (not mandatory) and that the sentencer considered the defendant's youth.

Current State of Juvenile LWOP

As of 2024, 28 states plus D.C. have banned juvenile life without parole entirely. The population of juveniles serving LWOP has declined 44% since Miller was decided.

States that have explicitly banned juvenile LWOP include Connecticut, Delaware, Hawaii, Massachusetts, Nevada, Texas, Vermont, West Virginia, Wyoming, and many others.
