Case 000878

Posted on by Gary McCurdy

Error and/or relief

The court’s use of the kill zone instruction was factually unsupported and should not have been given and the court’s instruction identified a primary target not supported by the evidence.

First Holding:

To prove the crime of attempted murder, the prosecution must establish ‘the specific intent to kill and the commission of a direct but ineffectual act toward accomplishing the intended killing. To be guilty of attempted murder, the defendant must intend to kill the alleged victim, not someone else. The defendant’s mental state must be examined as to each alleged attempted murder victim.

Authority:

People v. Canizales (2019) 7 Cal.5th 591, 602

People v. Bland (2002) 28 Cal.4th 313, 328

Second Holding:

To be guilty of attempted murder under an aiding and abetting theory, the defendant must share the specific intent of the direct perpetrator, that is to say, the person must know the full extent of the direct perpetrator’s criminal purpose and must give aid or encouragement with the intent or purpose of facilitating the direct perpetrator’s commission of the crime. In short, to be guilty of attempted murder as an aider and abettor, the defendant must intend to kill.

Authority:

People v. Lee (2003) 31 Cal.4th 613, 624, superseded by statute on other grounds as stated in People v. Rodriguez (2022) 75 Cal.App.5th 816, 823–824

People v. McCoy (2001) 25 Cal.4th 1111, 1118

Third Holding:

The Supreme Court has expressly embraced the concept of a concurrent intent to kill as a permissible theory for establishing the specific intent requirement of attempted murder. This concurrent intent theory is referred to as the “kill zone.” Under the kill zone theory, a defendant may be convicted of the attempted murder of an individual who was not the defendant’s primary target.

The kill zone theory permits a jury to infer a defendant’s intent to kill an alleged attempted murder victim from circumstantial evidence (the circumstances of the defendant’s attack on a primary target).

Authority:

People v. Canizales (2019) 7 Cal.5th 591, 596-597, 602

People v. Mumin (2023) 15 Cal.5th 176, 193

Fourth Holding:

The kill zone theory may properly be applied only when a jury concludes:

(1) the circumstances of the defendant’s attack on a primary target, including the type and extent of force the defendant used, are such that the only reasonable inference is that the defendant intended to create a zone of fatal harm—that is, an area in which the defendant intended to kill everyone present to ensure the primary target’s death—around the primary target, and (2) the alleged attempted murder victim who was not the primary target was located within that zone of harm.

Relevant factors in determining whether defendant intended to create a kill zone are (1) number of shots fired, (2) nature of the zoned area, (3) distance between primary target and others, (4) distance between defendant and others, (5) type of weapon used, and (6) whether anyone was hit.

Authority:

People v. Canizales (2019) 7 Cal.5th 591, 607

Fifth Holding:

Our inquiry on appeal is whether substantial evidence was presented to support a reasonable inference by the jury that defendant intended to create a zone of fatal harm around a primary target.

Justification for instructing on the kill zone theory requires substantial evidence that: (1) the defendant intended to kill a primary target; (2) he concurrently intended to achieve that goal by killing all others in the fatal zone he creates; and (3) the alleged attempted murder victim was in that zone.

These requirements must be strictly adhered to in order to protect against an improper attempted murder conviction based only on a conscious disregard for life because the kill zone theory does not apply where the defendant merely subjected persons near the primary target to lethal risk.

Because use or attempted use of force that merely endangered everyone in the area is insufficient to support a kill zone instruction, trial courts must exercise caution when determining whether to permit the jury to rely upon the kill zone theory.

Indeed, as stated in Canizales, we anticipate there will be relatively few cases in which the theory will be applicable and an instruction appropriate.

Authority:

People v. Mumin (2023) 15 Cal.5th 176, 203

People v. Canizales (2019) 7 Cal.5th 591, 607-608

Sixth Holding:

Fundamental to the kill zone theory is a particular relationship between the primary target, the means of the attack, and the secondary target. Specifically, the would-be secondary targets must be endangered not because they were specifically targeted by defendant but because the defendant has a primary target and reasons that he cannot miss that intended target if he kills everyone in the area in which the target is located.

Authority:

People v. Mumin (2023) 15 Cal.5th 176, 203

(Gary note: The opinion goes on to analyze the facts in the case against the above principles to determine whether it was proper to instruct on the kill zone doctrine and whether the court correctly identified the specific target. It also analyzed the impact of the prosecutor’s summation on the matter. Because this is an unpublished opinion, and the importance lies only in its legal principles and the published authority in support of those principles, I am omitting the balance of the court’s discussion applying those principles in support of its conclusions that it was improper to instruct on kill zone in this case.)

Case 000852

Posted on by Gary McCurdy

Error and/or relief

The court erred in denying the defendant’s petition for resentencing under section 1172.6 at the prima facie stage. Remanded for an evidentiary hearing.

First Holding:

Morris held that an aider and abettor of murder must actually aid and abet the lethal act in order to be convicted of murder, we agree with defendant that the record of conviction does not show he was convicted as either the actual killer or as an aider and abettor who acted with the intent to kill as a matter of law,

Authority:

People v. Morris (2026) 19 Cal.5th 671, 678

Second Holding:

SB 1437 (2017-2018 Reg. Sess.), effective January 1, 2019, significantly limited the scope of California’s felony-murder rule and eliminated liability for murder under the natural and probable consequences doctrine through two key statutory provisions.

Section 189 was amended so that a defendant is liable for felony murder only if he was (1) the actual killer, (2) a direct aider and abettor with the intent to kill, or (3) a major participant in the underlying felony and acted with reckless indifference to human life.

Section 188 was amended to impose a new requirement that, except in cases of felony murder, a principal in the crime of murder can only be convicted where he or she acted with malice aforethought, and malice shall not be imputed to a person based solely on his or her participation in a crime.

Third Holding:

A person convicted of felony murder or other theory under which malice is imputed to a person based solely on that person’s participation in a crime may file a petition with the court that sentenced the petitioner to have the petitioner’s murder conviction vacated and to be resentenced.

Authority:

PEN 1172.6

Fourth Holding:

Courts may not engage in factfinding at the prima facie stage. The court takes petitioner’s factual allegations as true and makes a preliminary assessment regarding whether the petitioner would be entitled to relief if his or her factual allegations were proved. If so, the court must issue an order to show cause.

A court should not reject the petitioner’s factual allegations on credibility grounds without first conducting an evidentiary hearing. At the prima facie hearing, the court may consider the record of conviction. The record of conviction includes jury verdicts, jury instructions, and closing arguments.

This does not include our appellate opinion. The factual summary in an appellate opinion is not evidence that may be considered at an evidentiary hearing to determine a petitioner’s eligibility for resentencing. If such evidence may not be considered at an evidentiary hearing to determine a petitioner’s ultimate eligibility for resentencing, we fail to see how such evidence could establish, as a matter of law, a petitioner’s ineligibility for resentencing at the prima facie stage.

If the petition and record in the case establish conclusively that the defendant is ineligible for relief, the trial court may dismiss the petition.

Sixth Holding:

For a person to be convicted of murder as an aider and abettor, the person must aid and abet the actual killer in the lethal act itself, and not just in the underlying felony.

Here, the record of conviction does not establish as a matter of law that defendant participated in aiding and abetting the kidnapping and other acts that led to the victim’s death and that he acted with the intent to kill. We thus reverse the trial court’s order and remand the matter with directions to issue an order to show cause and to conduct an evidentiary hearing.

Case 000802

Posted on by Gary McCurdy

Error and/or relief

Because the record of conviction did not establish the defendant was ineligible for relief as a matter of law, we reverse and remand for the trial court to set an evidentiary hearing under section 1172.6(d).

First Holding:

In 2019, the legislature enacted SB 1437, which amended the state’s murder laws to ensure culpability was commensurate with liability. The legislature later expanded its amendments with SB 775. SB 775 allowed defendants to seek resentencing if their convictions rested on any theory under which malice is imputed to a person based solely on that person’s participation in a crime, and they could not presently be convicted of murder or attempted murder because of changes to Section 188 or 189 made effective January 1, 2019.

To seek such relief, a defendant must file a petition under what is now section 1172.6. If petitioners make a prima facie showing that they are eligible for relief, the trial court must set an evidentiary hearing. If the record of conviction shows that the petitioner is ineligible for relief as a matter of law, the court may deny the petition at the prima facie stage.

People v. Maldonado (2023) 87 Cal.App.5th 1257

Third Holding:

In Maldonado, the court traced how a defendant could be convicted of first degree murder without a requirement that the jury find the defendant harbored malice. It noted that CALCRIM No. 401 only requires an intent to aid and abet a crime. In the murder context, this instruction can muddy the waters because the crime is not necessarily the act that caused the death or may not be an act that would require a conscious disregard of human life.

Case 000784

Posted on by Gary McCurdy

Error and/or relief

The trial court erred in denying the defendant’s motion to recall his sentence under section 1172.6. The evidence was insufficient to prove he is guilty of murder and attempted murder beyond a reasonable doubt.

First Holding:

SB 1437 (2017-2018 Reg. Sess.) eliminated the natural and probable consequences doctrine as it relates to murder to ensure a person’s sentence is commensurate with his or her criminal culpability. Specifically, it amended section 188 by adding a requirement that, except as stated in section 189(e), all principals to murder must act with express or implied malice to be convicted of that crime. SB 775 (2021-2022 Reg. Sess.) extended relief to defendants convicted of attempted murder, but only if their convictions were based on the natural and probable consequences doctrine.

Second Holding:

SB 1437 also created a procedural mechanism for defendants with eligible murder convictions to seek retroactive relief under the amended law. Under section 1172.6, if a petitioner makes a prima facie showing of entitlement to relief, the trial court must issue an order to show cause and hold an evidentiary hearing.

At that hearing, the court sits as an independent fact finder and the prosecution has the burden of proving beyond a reasonable doubt that the defendant is guilty of murder or attempted murder under the amended law. The parties may offer new or additional evidence at the hearing.

Third Holding:

Under direct aiding and abetting principles, an accomplice is guilty of an offense perpetrated by another [e.g., murder] if the accomplice aids the commission of that offense with knowledge of the direct perpetrator’s unlawful intent and with an intent to assist in achieving those unlawful ends. The defendant must not only know the direct perpetrator’s intent to commit murder, but he or she must share that intent. And, aiding and abetting the commission of a crime requires some affirmative action. The word aids refers only to overt or affirmative forms of assistance.

Sixth Holding:

Although intent to kill is certainly blameworthy, it is insufficient standing alone to render a person culpable for another’s acts. The aider and abettor must know the direct perpetrator intends to commit the murder and intend to aid the direct perpetrator in its commission. It is this mental relationship to the perpetrator’s acts that confers liability on the aider and abettor.

We cannot presume that because members of the defendant’s group belonged to the same gang, they must have known each other’s intent. Indeed, the law does not recognize a rule of guilt by association. We insist on proof of a defendant’s knowledge of, and specific intent to further, the group’s unlawful ends. Without knowledge of his cohort’s intent to kill, any of the defendant’s subsequent acts cannot constitute the actions necessary to establish aider and abettor liability.

Error and/or relief

We reverse the juvenile court’s finding that the minor committed murder as an aider and abettor with implied malice.

First Holding:

An aider and abettor of murder must actually aid and abet the lethal act in order to be convicted of murder.

Authority:

People v. Morris (2026) 19 Cal.5th 671, 678

Second Holding:

The trial court announced its finding that, to be liable for an implied malice murder, a direct aider and abettor must, by words or conduct, aid the commission of the life endangering act, not the result of that act. The court treated the robbery as the life-endangering act that resulted in the victim’s death.

The court went on to state that the People have proved beyond a reasonable doubt that the minor was an aider and abettor to the robbery with knowledge that his compatriots intended to commit the robbery; did, in fact, intend to aid the perpetrators in the commission of the robbery or attempted robbery, and had knowledge that the act was dangerous to human life.

The opinion in Morris was issued long after the juvenile court sustained the petition, and under Morris, the court’s reasoning was in error.

Authority:

People v. Morris (2026) 19 Cal.5th 671

Third Holding:

When considering a challenge to the sufficiency of the evidence to support a conviction, we review the entire record in the light most favorable to the judgment to determine whether it contains substantial evidence—that is, evidence that is reasonable, credible, and of solid value—from which a reasonable trier of fact could find the defendant guilty beyond a reasonable doubt.

We determine whether, after viewing the evidence in the light most favorable to the prosecution, any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt. In so doing, a reviewing court presumes in support of the judgment the existence of every fact the trier could reasonably deduce from the evidence.

The same standard of review governs our review of the sufficiency of evidence in juvenile delinquency cases.

Murder is the unlawful killing of a human being, or a fetus, with malice aforethought. An unlawful killing during the commission of a felony is also murder. Second degree implied malice murder is the unlawful killing of a human being with malice aforethought but without the additional elements, such as willfulness, premeditation, and deliberation, that would support a conviction of first degree murder.

Fifth Holding:

Malice is implied when the killing is proximately caused by an act, the natural consequences of which are dangerous to life, which act was deliberately performed by a person who knows that his conduct endangers the life of another and who acts with conscious disregard for life. In short, implied malice requires a defendant’s awareness of engaging in conduct that endangers the life of another—no more, and no less. This definition is referred to as “simple implied malice murder.”

Regarding aiders and abettors, in order to be convicted of murder, a principal in a crime shall act with malice aforethought. Malice shall not be imputed to a person based solely on his or her participation in a crime.

In the context of implied malice murder, the aider and abettor must know the perpetrator intends to commit a life-endangering act, intend to aid the perpetrator in the commission of that act, know the act is dangerous to human life, and act in conscious disregard for human life.

Ninth Holding:

Murder also requires an actus reus. In the context of implied malice, the actus reus required of the perpetrator is the commission of a life-endangering act. For the direct aider and abettor, the actus reus includes whatever acts constitute aiding the commission of the life-endangering act.

Thus, to be liable for an implied malice murder, the direct aider and abettor must, by words or conduct, aid the commission of the life-endangering act, not the result of that act.

Section 189(e)(2) requires a nonkiller to aid the actual killer in the lethal act.

While the language of Penal Code section 188(a)(3), differs from section 189(e), pursuant to section 188(a)(3), a direct aider and abettor must act with malice aforethought, and act with intent to aid the life-endangering act of the direct perpetrator that proximately causes the death.

Implied malice murder requires attention to the aider and abettor’s mental state concerning the life endangering act committed by the direct perpetrator, such as shooting at the victim, or, as in this case, stabbing him. In other words, the aider and abettor must know the perpetrator intends to commit a life-endangering act, intend to aid the perpetrator in the commission of that act, know the act is dangerous to human life, and act in conscious disregard for human life. Even if the act results in a death that is accidental, the circumstances surrounding the act may evince implied malice.

Thirteenth Holding:

Instead, with the exception of section 189(e), a conviction for murder requires that a person act with malice aforethought and that a person’s culpability for murder must be premised upon that person’s own actions and subjective mens rea.

We conclude the legislative language of Penal Code section 188(a)(3) requires a finding that the accused actually aided the perpetrator in the commission of the life-endangering act, and that the accused’s participation in a dangerous felony as an aider and abettor cannot form the basis for finding implied malice.

Only in this way will a finding that the accused aided and abetted in the commission of implied malice murder reflect a determination of the person’s guilt based on his own actions and subjective intent.
