What Is Homicide Under California Law?

Homicide is the killing of one human being by another. Not all homicide is criminal. California law distinguishes between criminal homicide and justifiable or excusable homicide. Justifiable homicide includes killings in lawful self-defense or defense of others where the force used was reasonable and necessary under the circumstances. Excusable homicide covers accidental killings that occurred without criminal negligence or unlawful intent.

Criminal homicide in California falls into two main categories: murder and manslaughter. The distinction between them turns primarily on the presence or absence of malice aforethought and the circumstances surrounding the killing.

Murder in California — First Degree and Second Degree

Criminal homicide in California falls into two main categories: murder and manslaughter. The distinction between them turns primarily on the presence or absence of malice aforethought and the circumstances surrounding the killing.

Murder in California — First Degree and Second Degree

Murder under Penal Code 187 PC is the unlawful killing of a human being or fetus with malice aforethought. Malice can be express or implied. Express malice is a deliberate intention to kill. Implied malice exists when the defendant deliberately performs an act with a high probability of causing death with a conscious disregard for human life.

First-Degree Murder

First-degree murder under Penal Code 189 PC applies when the killing is willful, deliberate, and premeditated. It also applies to killings committed by specific methods including poison, lying in wait, or use of a destructive device, and to killings that occur during the commission of certain specified felonies under the felony murder rule. The penalty for first-degree murder is 25 years to life in state prison. With special circumstances such as murder for financial gain, murder of a police officer, or multiple murders the penalty can be life without the possibility of parole or death.

Second-Degree Murder

Second-degree murder is any murder that does not meet the criteria for first degree. It involves malice but lacks the premeditation and deliberation required for first-degree treatment. A person who shoots into a crowd without intending to kill a specific person but with conscious disregard for human life can be charged with second-degree murder. The base sentence is 15 years to life in state prison with enhancements that can increase the term significantly depending on the circumstances and the use of a firearm.

The Felony Murder Rule in California

California’s felony murder rule historically allowed anyone who participated in a dangerous felony to be charged with murder if a death occurred during the commission of that felony even if they did not intend to kill anyone and did not personally cause the death. Senate Bill 1437 significantly reformed the felony murder rule in 2019.

Under the reformed rule felony murder liability now requires that the defendant was the actual killer, acted with intent to kill as a direct aider and abettor, or was a major participant in the underlying felony who acted with reckless indifference to human life. The reform eliminated liability for defendants who played a minor role in a felony and had no knowledge that anyone would be killed. Defendants convicted under the old rule may be eligible to petition for resentencing under the new standard.

Manslaughter in California — Voluntary, Involuntary, and Vehicular

Manslaughter under Penal Code 192 PC is the unlawful killing of a human being without malice aforethought. It is divided into three categories:

Voluntary Manslaughter

The intentional killing of another person in the heat of passion or upon a sudden quarrel. The provocation must be sufficient to cause a reasonable person to lose self-control and the killing must occur before the defendant had time to cool down. Voluntary manslaughter carries 3, 6, or 11 years in state prison. It is frequently the charge sought as a reduction from second-degree murder when the circumstances support a heat of passion defense.

Involuntary Manslaughter

An unintentional killing that results from criminal negligence or from the commission of an unlawful act not amounting to a felony. The killing is not purposeful but the defendant’s conduct was so reckless that a reasonable person would have recognized the risk of death. Involuntary manslaughter carries 2, 3, or 4 years in state prison.

Vehicular Manslaughter

Killing a person while operating a vehicle through gross negligence or in the commission of an unlawful act. Standard vehicular manslaughter under PC 192(c) carries up to one year in county jail as a misdemeanor or up to 6 years in state prison as a felony. Gross vehicular manslaughter while intoxicated under PC 191.5 carries up to 10 years in state prison.

Key Legal Distinctions That Determine the Charge

The difference between first-degree murder, second-degree murder, voluntary manslaughter, and involuntary manslaughter is often the difference between 25 years to life and a sentence of 3 or 4 years. The critical factors that determine which charge applies include:

  • Premeditation and deliberation: whether the defendant thought about and decided to kill before acting
  • Malice aforethought: whether the defendant intended to kill or acted with conscious disregard for human life
  • Heat of passion: whether adequate provocation caused the defendant to lose self-control before a reasonable cooling-off period
  • Criminal negligence: whether the defendant’s conduct fell so far below the standard of care that it constitutes criminal recklessness
  • Role in the underlying felony: under the reformed felony murder rule whether the defendant was the actual killer or a major participant acting with reckless indifference

These distinctions are not academic. They are the legal battlegrounds where homicide cases are won and lost and where the difference between the defense strategy pursued can determine whether a client serves 3 years or spends the rest of their life in prison.
