A Tennessee attempted murder sentence depends first on whether the charge is attempted first-degree or attempted second-degree murder. Attempted first-degree murder is a Class A felony carrying 15 to 60 years in prison, and for offenses committed on or after July 1, 2022, the entire sentence must be served with no parole and no sentence-reduction credits. Attempted second-degree murder is a Class B felony carrying 8 to 30 years, with release eligibility as early as 30% of the sentence for a standard offender. Where a defendant falls within those ranges depends on prior convictions, whether a firearm was used, whether the offense was gang-related, and who the victim was.
Base Sentence Ranges
Tennessee’s sentencing statute divides felony defendants into three ranges based primarily on prior felony convictions: Range I (standard offender), Range II (multiple offender), and Range III (persistent offender).1Justia. Tennessee Code 40-35-112 – Sentence Ranges The judge then sets an exact term within the applicable range using statutory enhancement and mitigating factors, including cruelty, position of trust, cooperation, or a minimal prior record.2Justia. Tennessee Code 40-35-114 – Enhancement Factors
Attempted First-Degree Murder (Class A Felony)
Criminal attempts in Tennessee are normally classified one step below the completed offense, but attempted first-degree murder is a specific exception that keeps the charge at Class A, the same classification as a completed second-degree murder.3FindLaw. Tennessee Code 39-11-117 – Classification of First Degree Murder The prison terms are:
- Range I (standard offender): 15 to 25 years
- Range II (multiple offender): 25 to 40 years
- Range III (persistent offender): 40 to 60 years
Attempted Second-Degree Murder (Class B Felony)
Attempted second-degree murder follows the general rule and drops one classification below the completed offense:
- Range I (standard offender): 8 to 12 years
- Range II (multiple offender): 12 to 20 years
- Range III (persistent offender): 20 to 30 years
What Separates the Two Charges
The gap between an 8-year floor and a 15-year floor turns on one legal element: premeditation. First-degree murder requires a killing done after reflection and judgment, meaning the intent to kill formed before the act. No specific amount of time is required, but the defendant must have been sufficiently free from excitement and passion to form that intent.4Justia. Tennessee Code 39-13-202 – First Degree Murder Second-degree murder is a knowing killing without that prior deliberation — the classic example being a sudden decision to kill during a heated confrontation.5Justia. Tennessee Code 39-13-210 – Second Degree Murder
Because attempted murder requires that the defendant intended to kill and took a substantial step toward carrying it out, no actual injury is necessary for either charge.6Justia. Tennessee Code 39-12-101 – Criminal Attempt The state’s proof of premeditation is often where cases are won and lost. Defense attorneys who can show the defendant acted impulsively rather than deliberately may push a case from attempted first-degree to attempted second-degree murder, cutting the minimum sentence roughly in half.
Enhancements That Add Time
Several statutory enhancements stack additional years on top of the base sentence, and some carry their own mandatory minimums served consecutively.
Firearm Enhancement
Possessing a firearm during the commission of a dangerous felony is a separate offense with a consecutive sentence. A first-time offender faces a mandatory minimum of six years added to the attempted murder sentence. With a prior felony, the minimum rises to ten years. A defendant with a prior conviction under the firearm-enhancement statute itself faces at least fifteen years, served at 100% with no credits.7Justia. Tennessee Code 39-17-1324 – Offense of Possessing a Firearm During Commission of a Dangerous Felony For a Range I offender convicted of attempted first-degree murder involving a firearm, the practical minimum becomes 21 years: 15 for the attempt plus 6 for the weapon charge.
Gang Enhancement
When the offense was committed for the benefit of a criminal gang or at the direction of gang leadership, the charge is punished one classification higher than it would normally carry. Attempted second-degree murder moves from Class B into Class A sentencing ranges. Because attempted first-degree murder is already Class A, the enhancement instead sets the presumptive sentence at the top of the defendant’s range. If the defendant was a gang leader or organizer, the enhancement is two classifications higher rather than one.8FindLaw. Tennessee Code 40-35-121 – Criminal Gang Offense Enhancement
Law Enforcement and First Responder Victims
Attempted first-degree murder is the only attempt offense in Tennessee that can produce a life sentence. If the victim was a law enforcement officer, correctional officer, firefighter, paramedic, or emergency rescue worker performing official duties, and the defendant knew or should have known that role, the court may impose life without the possibility of parole.4Justia. Tennessee Code 39-13-202 – First Degree Murder
How Much of the Sentence Is Actually Served
The nominal sentence and the time actually served can differ substantially, and the difference depends heavily on which charge and which offense date apply.
Attempted First-Degree Murder: 100% Service
For any attempted first-degree murder committed on or after July 1, 2022, the defendant must serve 100% of the sentence imposed. No parole. No sentence-reduction credits of any kind.9Justia. Tennessee Code 40-35-501 – Release Eligibility Status – Calculations A 20-year sentence means 20 calendar years behind bars.
For offenses committed between July 1, 2013, and June 30, 2022, the rule is slightly less harsh. If the victim suffered serious bodily injury, the defendant must serve at least 85% of the sentence before becoming release-eligible, and credits cannot reduce that below 75%.9Justia. Tennessee Code 40-35-501 – Release Eligibility Status – Calculations
Attempted Second-Degree Murder: Standard Release Schedule
Attempted second-degree murder is not on the 100% service list. Release eligibility follows the standard percentage tied to the offender range:
- Range I: eligible after serving 30% of the sentence
- Range II: eligible after serving 35%
Those percentages can drop further with earned sentence-reduction credits, and career offenders face a higher threshold.10FindLaw. Tennessee Code 40-35-501 – Release Eligibility Status Eligibility is not release. The Tennessee Board of Parole weighs the offense, institutional conduct, rehabilitation, and victim input, and it can deny parole even after the defendant hits the eligibility date.
Probation Is Effectively Off the Table
Probation is available in Tennessee only when the actual sentence imposed is ten years or less.11Justia. Tennessee Code 40-35-303 – Probation – Eligibility – Terms Attempted first-degree murder carries a 15-year floor for even a Range I offender, so probation is categorically unavailable. Attempted second-degree murder at the very bottom of the Range I band (8 years) technically fits inside the probation window, but courts rarely grant it for an attempted killing. If probation were imposed, it would come with intensive supervision, electronic monitoring, and mandatory counseling, and any violation would trigger imprisonment for the full term.
Where Sentences Get Challenged
Because the length of a Tennessee attempted murder sentence hinges on the defendant’s mental state at the time of the act, the fight over sentencing often begins as a fight over which charge sticks. Defense strategies commonly attack the state’s proof of intent or premeditation:
- Arguing that conduct was reckless or impulsive rather than deliberate, which can support a lesser charge such as aggravated assault or reckless endangerment.
- Arguing that any intent to kill formed in the heat of the moment, which at most supports attempted second-degree murder rather than attempted first-degree.
- Raising self-defense, which permits deadly force without retreating when the defendant reasonably believed they faced imminent death or serious injury in a place they had a right to be.12FindLaw. Tennessee Code 39-11-611 – Self-Defense
- Raising insanity, a complete defense that requires clear and convincing evidence the defendant could not appreciate the nature or wrongfulness of the act because of a severe mental disease or defect.13Justia. Tennessee Code 39-11-501 – Insanity
Moving a case from attempted first-degree to attempted second-degree murder can drop the minimum from 15 years served day-for-day to 8 years with parole eligibility at 30%. That single distinction is often the largest variable in the entire sentence.
