Understanding Life Sentences in Missouri

If you or a loved one is facing, or has been charged with, a life sentence, it is important to understand exactly what a life sentence entails and what the end result can look like.  This type of sentence is much different than a  municipal charge.

What is a life sentence?

Believe it or not, this is not a simple question to answer and it depends on the jurisdiction.

In Missouri, a life sentence is considered a 30-year prison sentence with one exception. A first-degree murder conviction states that the life sentence imposed means that the person convicted will die in prison.

In the federal court system, a life sentence means that the person convicted will remain in prison until their natural death, unless successfully appealed or shortened to a fixed term.

Can minors be charged with a life sentence without the possibility of parole?

In 2012, the Supreme Court ruled in the case of Miller v. Alabama that minors cannot be issued life sentences with no chance for parole except in the case of aggravated first-degree murder, based on the 8th Amendment outlawing cruel and unusual punishment.

What is the point of being charged with multiple life sentences?

At first glance, having a judge do this might seem to make no sense.  But, in the state system, remember that life sentences are essentially 30-year sentences, so two life sentences would effectively equal a 60-year sentence.

In the case of life sentences without a term limit (such as a first-degree murder in Missouri or a federal life sentence), having multiple consecutive life sentences ensures that the person convicted will remain in jail until their natural death even if one conviction is commuted (shortened) or overturned.

What are crimes that are eligible for life sentences?

There are two types of crimes eligible for life sentences – federal and state.  

Federal Crimes Eligible for Life Sentences

  • First Degree Murder
  • Treason

Other federal crimes could be eligible for life sentences as well if certain circumstances existed when the crime was committed.  For example, a life sentence could be imposed for kidnapping, if the person kidnapped was a minor who was sexually exploited and the kidnapper used a gun in the abduction.

You will notice that there are far fewer federal crimes eligible for life sentences, as compared to state charges, due to the fact that federal crimes are sentenced with the intent that the person convicted serve the entire term of the sentence.  No parole options exist in the federal system except for those convicted prior to November 1, 1987.

How much time will someone sentenced to life in Missouri actually serve?

As a general rule, the time served after which someone can be eligible for parole is dependent on how many prior convictions someone has:

  • One Prior – 40% of sentence (or until the age of 70 with 30% served)
  • Two Priors – 50% of sentence (or until the age of 70 with 40% served)
  • Three or More Priors – 80% of sentence (or until the age of 70 with 40% served)

There are certain crimes that do not allow a parole hearing until a certain portion of the sentence has been served no matter how many prior convictions someone has.  Those crimes are:

  • Armed Criminal Action – 3 years for first conviction, 5 years for second conviction, and 10 years for third conviction
  • Aggravated and Chronic DWI Offenders – Aggravated – 60 Days; Chronic – 2 years
  • Capital Murder – 50 years
  • Discharging of a Firearm in the Committal of a Crime – 10 years for prior offenders
  • Enticement of a Child Less than 15 – 5 years
  • Failure to Register as a Sex Offender, 3rd Offense – 2 years
  • Forcible Rape or Sodomy of a Victim Less than 12 – 30 years
  • First Degree Involuntary Manslaughter – 85% of sentence
  • Pharmacy Robbery in the First Degree – 10 years
  • Pharmacy Robbery in the Second Degree – 5 years
  • Prior or Persistent Domestic Violence Offenders – 6 months

And lastly, there are some crimes that are ineligible for parole:

  • Child Molestation in the First Degree of a Child Less than 12 (when there was serious physical violence of the offender was a repeat offender)
  • Discharging of a Firearm in the Committal of a Crime (by persistent offenders)
  • Domestic Assault in the First Degree (for persistent domestic violence offenders)
  • Drug Trafficking Offenses (in certain cases)
  • Murder in the First Degree
  • Persistent Sexual Offender
  • Tampering with Victim/Witness

Life sentences are obviously a very big deal and especially in states like Missouri where life doesn’t necessarily mean life, they can be quite confusing as well.  At Twibell Pierson Criminal Law, we have handled a lot of cases with life sentences on the line and won those cases.  Even if convicted, having an experienced defense attorney on your side can help minimize you or your loved one’s time served.

What Does a “15 Years to Life” Sentence Mean?

A sentence of 15 years to life is an indeterminate sentence: the minimum term is 15 years and the maximum is life. Serving the minimum makes an inmate eligible for parole — it does not guarantee release — and the exact timing of parole review depends on the jurisdiction’s laws, applicable sentence credits, and special eligibility rules.

  • Minimum Term: The defendant becomes eligible for parole after the minimum term. Board evaluations and consultations may happen at different points depending on the state — some jurisdictions begin parole-board consultations years before the first suitability hearing.
  • Indeterminate Maximum: The state retains legal custody for the rest of the inmate’s natural life if parole is not granted.
  • Parole Grant Factors: Institutional behavior, rehabilitation programs, and victim input inform whether the parole board grants release; legal eligibility itself is set by the sentence and applicable law.

How Long Is a Life Sentence in the USA and Missouri?

A life sentence never simply expires. How long a life sentence means in practice depends on the jurisdiction and the offense:

  • Federal System: Federal parole was abolished for offenses committed on or after November 1, 1987. A modern federal life sentence generally means imprisonment for the remainder of the person’s life unless the sentence is overturned, reduced, or commuted. Sentences for older offenses can follow different parole rules.
  • Missouri State Law: Missouri’s sentencing statute (RSMo § 558.019) uses a 30-year figure when calculating minimum prison terms for parole eligibility — but that number is a calculation tool, not an expiration date. A life sentence does not end after 30 years.
  • Dangerous-Felony Rule: Where the 85% minimum prison term rule applies to a life sentence, 85% of the 30-year calculation is 25.5 years. The statute also includes an alternative path for a defendant who reaches age 70 after serving at least 40% of the sentence, and offense-specific restrictions can still apply. These calculations do not turn life without parole into a parole-eligible sentence.

What Does 2 Life Sentences Mean and Why Are They Imposed?

Receiving two life sentences means the judge imposed separate life terms for multiple criminal counts, ordered to run either consecutively (one after the other) or concurrently (at the same time). The practical effect of consecutive life terms depends on whether parole is available and how the jurisdiction calculates multiple sentences.

  • Consecutive Life Terms: Consecutive sentences can significantly delay parole eligibility, but the exact calculation is governed by specific statutes and correctional rules rather than a universal formula.
  • Effect of Appeals: If one conviction is overturned on appeal, an unaffected conviction and sentence may remain in effect — though an appellate ruling can also affect multiple counts or require resentencing.
  • Proportional Accountability: Multiple life sentences are imposed in cases involving multiple serious convictions, whether those convictions followed trials or guilty pleas.

The rules for federal felony sentencing and state sentencing calculations are complex, and the details change the realistic outcome of a case. If you or a loved one is facing homicide charges, a Missouri murder defense attorney can evaluate how multiple counts and sentencing rules would apply.
