California Murder Charges – Overview & Comprehensive Defense Strategies

Facing a Homicide Charge? Why Comprehensive Representation Matters

Being accused of murder under California Penal Code § 187 is one of the gravest situations a person can face. Convictions can result in decades behind bars, life without the possibility of parole (LWOP), or even capital punishment. Because law enforcement and prosecutors devote immense resources to homicide investigations, your defense must be equally robust. At Radford & Rome, LLP, our attorneys are former prosecutors with decades of combined experience. We know how the state builds homicide cases and how to dismantle them, and we serve clients in Los Angeles and throughout Southern California.

Categories of Homicide Charges

Understanding the different classifications of homicide is critical to formulating an effective defense. California law distinguishes several types of murder and manslaughter, each with its own elements and penalties. We summarize the major categories below; our companion articles provide deeper analysis of each.

First‑Degree Murder – Premeditation & Deliberation

Murder becomes first‑degree when the killing is willful, deliberate and premeditated or when it involves lying in wait, use of explosives or poisons, or is committed during certain felonies. Penalties include 25 years to life in state prison. If the murder involves a special circumstance listed in Penal Code § 190.2, such as killing for financial gain, multiple victims, killing a police officer, or murder during torture or a drive‑by shooting, the sentence increases to life without parole or the death penalty. (California currently has a moratorium on executions, but death sentences may still be imposed.)

Second‑Degree Murder – Intentional but Not Premeditated

If the prosecution cannot prove premeditation, the homicide is charged as second‑degree murder. This applies to intentional killings committed in the heat of the moment, or acts done with conscious disregard for human life, such as firing into a crowd or driving under the influence with prior DUI convictions. The penalty is 15 years to life, increased to 25 years to life if the victim is a peace officer. Sentencing enhancements for firearm use and prior strikes can add 10, 20 or 25 years to the term; see our discussion on enhancements below.

Felony Murder – Liability for Deaths During Dangerous Felonies

The felony murder rule holds participants in certain felonies liable for murder if someone dies during the commission or attempted commission of the felony. After Senate Bill 1437, a defendant may be convicted of felony murder only if they were the actual killer, intended to kill and aided the killer, were a major participant in the felony acting with reckless indifference to human life, or if the victim was an on‑duty law‑enforcement officer. First‑degree felony murder (during arson, robbery, burglary, carjacking, kidnapping, mayhem, torture or certain sex offenses) carries 25 years to life, LWOP or the death penalty. Second‑degree felony murder, which arises from inherently dangerous felonies not on the list, carries 15 years to life.

Attempted Murder – Trying but Failing to Kill

Attempted murder requires proof that the defendant intended to kill and took a direct step toward completing the murder. Attempted first‑degree murder is punished by life in state prison, while attempted second‑degree murder carries 5, 7 or 9 years. To secure a conviction, prosecutors must show both intent and a direct action beyond mere preparation.

Voluntary & Involuntary Manslaughter

When the prosecution cannot prove malice aforethought, the charge may be reduced to manslaughter. Voluntary manslaughter occurs when the defendant kills in a sudden quarrel or heat of passion. It is punishable by 3, 6 or 11 years in prison. Involuntary manslaughter applies when a death results from criminal negligence or a lawful act done without due caution. Penalties range from 2, 3 or 4 years in prison. Our separate article on manslaughter provides further information.

Common Defenses to Murder Charges

Mounting an effective defense requires understanding the legal justifications and partial defenses that can defeat or reduce a murder charge. For an in‑depth discussion, see our article Defenses to Murder Charges, but the following are commonly raised:

Self‑Defense / Defense of Others: Penal Code § 197 authorizes deadly force to repel an imminent threat of death or great bodily injury when the force is proportional and the defender was not the aggressor.
Accident / Lack of Intent: CALCRIM 510 recognizes that a homicide is excusable if it results from an accident during a lawful act conducted with reasonable care and without criminal negligence.
Manslaughter / Heat of Passion: Demonstrating that a killing occurred during a sudden quarrel or due to negligence, rather than malice, can reduce the charge to voluntary or involuntary manslaughter.
Mental Impairment & Insanity: Evidence of mental illness may negate the specific intent required for murder (diminished actuality). A complete insanity defense applies when, under the M’Naghten rule, the defendant did not understand the nature of the act or could not distinguish right from wrong.
Mistaken Identity / Alibi: CALCRIM 3400 instructs that the prosecution must prove the defendant was present at the crime; reasonable doubt about presence requires acquittal.

Special Circumstances & Sentence Enhancements

Certain aggravating factors elevate a first‑degree murder to special circumstances murder under Penal Code § 190.2, making the defendant eligible for LWOP or the death penalty. These factors include murder for financial gain, prior murder convictions, multiple victims, killing a police officer or witness, murders committed by bomb or poison, torture killings, drive‑by shootings, hate‑motivated murders, and killings by street gang members. Even with special circumstances, the jury must unanimously find the factor true; only then can the court impose LWOP or capital punishment.

In addition to special circumstances, California law imposes sentence enhancements for using a gun or committing murder for a gang. Penal Code § 12022.53 — known as the “10‑20‑life” law — adds 10 years to a sentence for merely using a firearm, 20 years for firing it, and 25 years to life if the gunshot causes great bodily injury or death. These enhancements are consecutive to the underlying sentence and apply to 19 serious felonies, including murder. Judges now have discretion to strike or dismiss firearm enhancements in the interest of justice.

Juveniles Charged with Murder

Minors accused of homicide face distinct procedures. Under Welfare & Institutions Code § 707, a prosecutor may seek to transfer a 16‑ or 17‑year‑old accused of any felony, or a 14‑ or 15‑year‑old accused of certain serious offenses, to adult court. The judge holds a fitness hearing to determine whether the minor is amenable to rehabilitation in the juvenile system. In deciding, the court considers factors such as the minor’s level of criminal sophistication, potential for rehabilitation, prior delinquency history, success of previous interventions, and the severity of the offense. Proposition 57 and subsequent reforms restrict prosecutors’ ability to directly file juvenile cases in adult court, and Senate Bill 1391 bars transfer for 14‑ and 15‑year‑olds except in limited circumstances. Our article on Juvenile Murder Charges explains these rules and defenses in detail.
