Attempted murder, charged under PC 664/187, carries a base sentence of 5, 7, or 9 years in state prison — but that number can jump to life in prison with the possibility of parole if the prosecution proves the attempt was willful, deliberate, and premeditated. Firearm enhancements can add another 10, 20, or even 25 years to life on top of the base sentence. In other words, the exact same underlying conduct can result in dramatically different penalties depending on a handful of specific legal factors, which is why understanding how these penalties are calculated matters so much if you’re facing this charge.

The Base Sentence: 5, 7, or 9 Years

When attempted murder is not proven to be premeditated, the sentencing range is 5, 7, or 9 years in state prison. Judges select the specific term within this “triad” based on factors in aggravation and mitigation — things like the defendant‘s criminal history, the severity of injury to the victim, the presence of any weapon, and the overall circumstances of the offense. This base sentence already reflects the seriousness with which California treats attempted murder, even without the premeditation enhancement, and it stands in sharp contrast to many other violent felonies with lower minimum terms.

The Premeditation Factor: The Difference Between Years and Life

The single biggest factor in an attempted murder sentence is whether the prosecution can prove the attempt was willful, deliberate, and premeditated. This does not require lengthy advance planning — California courts have held that premeditation can form quickly, even in a matter of seconds, as long as the decision to kill resulted from actual reflection rather than an unconsidered or rash impulse. If proven, this factor increases the potential sentence to life in state prison with the possibility of parole, rather than the fixed 5, 7, or 9-year triad, which represents one of the largest sentencing jumps for a single legal factor anywhere in California criminal law.

Courts typically look at three categories of evidence when evaluating premeditation:

  • Planning activity — evidence the defendant made arrangements or preparations before the attempt, such as acquiring a weapon in advance or seeking out the victim at a specific time and place.
  • Motive — evidence of a prior relationship or conduct suggesting a reason to kill the particular victim, such as a documented history of conflict or threats.
  • Manner of the attempt — evidence that the method used was particular or exacting enough to suggest a preconceived plan, rather than a spontaneous act arising from a sudden confrontation.

Because premeditation is such a significant sentencing factor, it is very often the central battleground in an attempted murder trial — sometimes more contested than the underlying question of whether the defendant intended to kill at all. Prosecutors will frequently attempt to piece together circumstantial evidence across all three categories to build a premeditation case, while the defense works to show the incident was spontaneous or reactive rather than planned.

Firearm Enhancements: Stacking Additional Years

If a firearm was used during the attempted murder, California’s firearm enhancement statutes can add substantial additional time on top of the base or premeditated sentence, with the specific enhancement depending on how the firearm was used:

  • Personal use of a firearm can add a fixed number of years.
  • Intentional and personal discharge of a firearm can add a longer fixed term.
  • Intentional and personal discharge of a firearm causing great bodily injury can add 25 years to life on top of the underlying sentence.

These enhancements are charged and proven separately from the underlying attempted murder charge, meaning a jury must find each specific firearm allegation true beyond a reasonable doubt independent of the attempted murder conviction itself. This separate proof requirement means a defendant can potentially be convicted of attempted murder while having a firearm enhancement allegation rejected by the jury, significantly reducing the total sentence compared to what the prosecution originally sought.

Attempted Murder of Specific Victims

California law imposes even more severe consequences when the intended victim was a peace officer, firefighter, or certain other public officials engaged in the performance of their duties, with enhanced minimum parole eligibility periods that can significantly extend the practical length of incarceration even within a life sentence. These enhanced provisions reflect a legislative judgment that attacks on public safety officers and officials warrant additional deterrence beyond the standard attempted murder framework.

Frequently Asked Questions

How Is “Specific Intent to Kill” Different From Regular Intent?

Specific intent to kill is a higher legal bar than the general intent required for many other crimes. It requires the prosecution to prove the defendant actually wanted the victim to die, not just that the defendant intended to commit a dangerous act or cause serious injury. This is one of the most commonly challenged elements in attempted murder cases, since evidence can sometimes support an inference of intent to injure or frighten without clearly establishing intent to kill. Prosecutors often rely on the nature and location of any injury, statements made by the defendant, and the specific method used to infer this intent, all of which can be challenged through careful cross-examination and alternative expert interpretation.

What’s the Relationship Between Attempted Murder and Assault Charges?

Assault with a deadly weapon, charged under PC 245, is often charged as an alternative to attempted murder when the evidence of specific intent to kill is weaker, or negotiated down to from an original attempted murder charge. Unlike attempted murder, assault with a deadly weapon does not require proof of intent to kill, only intent to commit an act that would likely result in the application of force. This makes it a significantly less severe charge, both in terms of proof required and potential sentencing, which is why it’s a common focus of plea negotiations in cases where intent to kill is genuinely disputed by the available evidence.

How the Victim’s Recovery Can Affect the Case

Because attempted murder, by definition, involves a victim who survives, the extent and nature of the victim’s recovery can play an unexpectedly significant role in how the case unfolds. Serious, permanent injuries can be used by the prosecution to support an inference of intent to kill, arguing that only an intent to cause death could explain the severity of harm inflicted. Conversely, minor or superficial injuries can sometimes support a defense argument that the true intent was to injure or frighten rather than kill. This is why medical records and expert testimony about the nature of the victim’s injuries often become a significant focus of both the prosecution’s and the defense’s case preparation.

Defending Against Attempted Murder Charges

Because attempted murder hinges so heavily on specific intent and, often, premeditation, defense strategies typically focus on the defendant’s true state of mind rather than disputing that a violent act occurred. Common approaches include presenting evidence that the defendant’s intent was to frighten or injure rather than kill, challenging the prosecution’s premeditation evidence, and, where applicable, raising self-defense or defense of others.

In our experience handling these cases throughout Los Angeles County, the earliest stages of an attempted murder case — before formal charges are even filed — often present the best opportunity to shape how the case is ultimately charged, since prosecutors have discretion over whether to pursue the premeditation allegation at all. Early engagement with the district attorney’s office, supported by a well-documented alternative narrative, can sometimes result in charges being filed without the premeditation allegation attached, dramatically reducing the sentencing exposure from the outset. Waiting until formal charges are already filed to begin building this record often forecloses opportunities that were available immediately after arrest.

How Attempted Murder Sentencing Compares to Completed Murder

It’s worth pausing on just how close attempted murder sentencing can come to completed murder sentencing, which often surprises people who assume that surviving an attack should result in a substantially lower charge across the board. While the base 5, 7, or 9-year triad is significantly lower than a murder sentence, premeditated attempted murder’s life-with-parole sentence sits much closer to second-degree murder’s 15-years-to-life range than most people expect. This narrow gap reflects a deliberate legislative choice: California treats the intent to kill, once proven with premeditation, as nearly as serious as a completed killing, precisely because the outcome — whether the victim lives or dies — often depends on factors outside the defendant’s control, such as the speed of emergency medical response or the precise location of an injury.

Key Takeaways

  • The base sentence for attempted murder without premeditation is 5, 7, or 9 years in state prison.
  • A finding of premeditation increases the sentence to life with the possibility of parole.
  • Firearm enhancements can add 10 years to 25-years-to-life on top of the base sentence.
  • Attempted murder of a peace officer or public official carries even more severe consequences.
  • The nature and severity of the victim’s injuries often becomes central evidence for both sides.
  • Specific intent to kill is a high legal bar, and challenging it is a central defense strategy.
