Types and Categories of Murder in California

Understanding Homicide Charges and Penalties

California’s homicide statutes are complex. The penalties for a killing vary dramatically depending on whether the prosecutor alleges first‑degree murder, second‑degree murder, felony murder, attempted murder or manslaughter. Knowing how prosecutors categorize a homicide — and the defenses available — is essential if you or someone you love is facing charges. Below is an overview of the primary types of murder and manslaughter under California law, along with the penalties and key legal elements.

Radford & Rome, LLP is a criminal defense firm based in Los Angeles with a statewide reach. Our attorneys handle cases in Los Angeles, Orange, San Bernardino, Riverside, Ventura and San Diego counties. We combine decades of experience and a deep understanding of California’s homicide statutes to achieve the best possible results for our clients.

First‑Degree Murder – Premeditation and Special Circumstances

Under Penal Code § 187, murder is the unlawful killing of a human being with malice aforethought. A murder becomes first‑degree when it is willful, deliberate and premeditated, when it involves lying in wait or the use of an explosive or destructive device, or when it falls under the felony murder rule. To convict on this charge, prosecutors must prove that the defendant formed the intent to kill, deliberated on that decision and carried out the act.

Penalties:

Standard penalty: First‑degree murder is punishable by 25 years to life in state prison.
Special circumstances: When aggravating factors listed in Penal Code § 190.2 are present — such as killing for financial gain, multiple victims, or killing a police officer — the sentence is either life without the possibility of parole (LWOP) or the death penalty. Governor Gavin Newsom has imposed a moratorium on executions, so no executions are currently being carried out, but death sentences may still be imposed.

Special considerations: Jury instruction CALCRIM 521 instructs jurors on the requirements for finding a murder willful, deliberate and premeditated and explains that certain methods, such as lying in wait or using a destructive device, automatically elevate a killing to first‑degree murder.

Second‑Degree Murder – Intentional but Not Premeditated

Second‑degree murder applies when the killing is intentional but not planned or deliberate. There is still malice aforethought, but no premeditation. Examples include firing a weapon into a crowd without aiming at a specific person or driving under the influence after prior DUI convictions and causing a fatal crash.

Penalties:

15 years to life in prison: Second‑degree murder carries an indeterminate term of 15 years to life.
Enhanced penalties: If the victim was a police officer, the sentence increases to 25 years to life, and firearm or prior‑strike enhancements can add 10, 20 or 25 years to the sentence, depending on whether the defendant used, fired or caused injury with a gun.

Special considerations: CALCRIM 520 instructs that second‑degree murder requires proof of an intentional act that naturally and probably would cause death, with conscious disregard for human life, but without premeditation.

Attempted Murder – PC 664/187

Attempted murder requires proof that the defendant intended to kill and took a direct step toward killing. Attempted first‑degree murder is punished by life in state prison, while attempted second‑degree murder carries 5, 7 or 9 years in prison. CALCRIM 600 instructs jurors that a “direct step” is an act that goes beyond preparation and would have resulted in death but for an outside interruption.

Felony Murder Rule – Penal Code § 189

California’s 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 person may be convicted of felony murder only if they (1) were the actual killer, (2) intended to kill and aided or abetted the killer, (3) were a major participant in the underlying felony and acted with reckless indifference to human life, or (4) killed an on‑duty police officer and knew or reasonably should have known the victim’s status. Negligent or accidental deaths during a felony generally do not qualify.

Felony murder comes in two degrees:

First‑degree felony murder: When a death occurs during the commission of enumerated felonies such as arson, robbery, burglary, carjacking, kidnapping, mayhem, torture or specified sex crimes. The penalty is 25 years to life, life without parole or, in rare cases, the death penalty.
Second‑degree felony murder: Applies to inherently dangerous felonies not listed above and carries 15 years to life. Courts determine on a case‑by‑case basis which felonies qualify.

Voluntary and Involuntary Manslaughter – Penal Code § 192

Manslaughter is the unlawful killing of another without malice. The law recognizes two main categories relevant here:

Voluntary Manslaughter (PC 192(a))

Voluntary manslaughter occurs when a person kills in the heat of passion or during a sudden quarrel. The killing is intentional, but the defendant was provoked in a way that would cause an average person to act rashly and without reflection. The punishment is 3, 6 or 11 years in state prison.

Involuntary Manslaughter (PC 192(b))

Involuntary manslaughter applies when someone unintentionally kills another person through criminal negligence or during the commission of a non‑felony offense. There is no intent to kill; rather, the death results from reckless conduct. The crime is punishable by 2, 3 or 4 years in prison. CALCRIM 580 explains that jurors must acquit of murder if they find the killing was unintentional and caused by negligence.

Vehicular Manslaughter (PC 192(c))

When an unintentional death occurs while driving, the prosecution may charge vehicular manslaughter under Penal Code § 192(c). The penalties depend on whether the driver acted with gross negligence or ordinary negligence and whether they were intoxicated. Punishments range from one year in county jail to six years in state prison; more serious DUI‑related deaths may be charged as Watson murder (second‑degree murder).

Choosing the Right Defense

Every homicide case is unique. The difference between a first‑degree murder charge and a manslaughter conviction often hinges on the specific facts: Was there premeditation? Was the defendant provoked or acting in the heat of passion? Did they take a direct step toward killing? Were they a minor participant in a felony? An experienced attorney can challenge the prosecution’s evidence and argue for reduced charges or dismissal.
