California First Degree Murder Laws
The unlawful killing of a human being -- homicide -- may be charged as murder or manslaughter. Murder requires a showing of "malice aforethought," which refers to the defendant's intent or state of mind. To prove a murder, the prosecutor must show that the defendant had express or implied malice. Express malice means that the defendant deliberately intended to commit murder. Alternatively, a prosecutor may show implied malice in the defendant's conduct that reflects an "abandoned and malignant heart." Implied malice may arise if the defendant acted without care for another person's safety or behaved with extreme recklessness.
First vs. Second Degree Murder
California recognizes two types of murder: first degree murder and second degree murder. First degree murder is reserved for especially heinous crimes involving premeditation, deliberation or deliberate planning, and intent to kill. State laws list the special circumstances that a prosecutor must use to charge a defendant with first degree murder. If none of the special circumstances apply, the prosecutor may pursue a charge of second degree murder.
Under California's first degree murder law, the prosecutor must show a premeditated, deliberate killing involving one of the special circumstances listed by the state laws of California. The means of killing that qualify a homicide as first degree murder include weapons of mass destruction, bombs or explosive devices, armor-piercing ammunition, poison, and firearms shot from a motor vehicle. State law also requires a charge of first degree murder when the killing occurred after the defendant's lying in wait or torture of the victim. First degree murder also includes killings committed while carrying out or attempting another felony such as burglary, robbery, rape, kidnapping, and other specified crimes.
If the victim survives three years and one day after the date when the cause of death allegedly occurred, California state laws include a presumption that the killing was not a criminal act of murder or manslaughter. The prosecutor must rebut the presumption in order to pursue a first degree murder charge.
