What Is the Difference Between Murder and Manslaughter in California?
April 20, 2025 | Nafiz M. Ahmed
Murder and manslaughter are both serious homicide charges under California law. While both involve the unlawful killing of another person, they are treated differently based on intent, circumstances, and how responsible the defendant is for the death.
Learning about the difference between the two can be important if you or someone you love is facing charges. Each offense has its own legal definition and possible penalties, which can have a major impact on the outcome of the case.
How California Defines Murder
Murder is the unlawful killing of a person with “malice aforethought.” Under California Penal Code 187 PC, malice can be express or implied. Express malice means there was an intent to kill. Implied malice means the person acted in a way that showed a clear disregard for human life.
There are three levels of murder in California:
- First-degree murder involves planning or special circumstances, such as lying in wait, using explosives, or committing murder during certain felonies like robbery or rape.
- Second-degree murder is intentional but not planned. These cases often involve impulsive actions that still show disregard for life.
- Capital murder is a type of first-degree murder with special circumstances that make the defendant eligible for the death penalty or life without parole.
All murder charges are felonies and come with harsh consequences. Penalties may include 15 years to life in prison, life without parole, or, in rare cases, the death penalty.
How California Defines Manslaughter
Manslaughter also involves the unlawful killing of another person, but without malice. That’s the key difference from murder.
California Penal Code 192 PC outlines three types of manslaughter, including:
- Voluntary manslaughter happens during a sudden fight or in the heat of passion. The person must have been provoked in a way that could cause a reasonable person to lose control.
- Involuntary manslaughter involves an unintentional killing that occurs while doing something legal but dangerous, without enough care.
- Vehicular manslaughter involves deaths caused by unsafe or negligent driving. This can range from basic carelessness to driving while under the influence.
While manslaughter is less serious than murder, it still carries heavy consequences. Voluntary manslaughter can lead to up to 11 years in prison. Involuntary and vehicular manslaughter can result in shorter but still significant sentences.
The Legal Difference Between Murder and Manslaughter in California
Whether a killing is considered murder or manslaughter can make a huge difference in a criminal case. Prosecutors look at the accused person’s state of mind, what happened before the incident, and whether they were provoked.
If the defense can show the act was not planned or happened in the heat of the moment, a murder charge might be reduced to manslaughter. That change can mean the difference between life in prison and a shorter sentence.
California law also allows for what’s called “imperfect self-defense.” This may apply when someone believed they needed to use deadly force to protect themselves, even if that belief wasn’t reasonable. In these cases, a murder charge might be reduced to voluntary manslaughter.
