The 187 code refers specifically to Section 187 of the California Penal Code, which defines the crime of murder. While it's widely recognized in popular culture, news, and hip-hop music, its actual legal weight comes from precise statutory definitions, specific evidentiary requirements, and decades of courtroom precedent.
Understanding how this specific statute works requires separating courtroom definitions from media myths. Let's break down what the statute actually says, how law enforcement uses the terminology, and why the number became embedded in American culture.
What California Penal Code 187 Actually Says
At its statutory core, Section 187 defines murder as the unlawful killing of a human being, or a fetus, with malice aforethought. The wording is precise, and every single word carries distinct legal obligations for prosecutors in a courtroom.
- Unlawful killing: The death cannot be legally justified or excused, such as in cases of legitimate self-defense or authorized law enforcement actions.
- Human being or a fetus: California law specifically expanded the definition to include fetuses, with distinct exceptions governing legal medical procedures and acts by the mother.
- Malice aforethought: This does not necessarily mean premeditation or planning over a long period. It can be express (a deliberate intention to take a life) or implied (an act displaying a conscious disregard for human life).
Prosecutors must prove beyond a reasonable doubt that the defendant committed the act, that they possessed the required mental state of malice, and that the act directly caused the victim's death. Without each of these elements meeting the statutory standard, a first- or second-degree murder charge cannot legally stand under this section.
Degrees of Murder Under the Statute
Section 187 establishes the framework for murder, but California law splits the offense into distinct degrees, carrying vastly different sentencing consequences.
First-degree murder generally involves willful, deliberate, and premeditated killing, or killings committed during the commission of specific inherently dangerous felonies like arson, rape, or robbery. Second-degree murder covers all other kinds of murders with malice aforethought that lack premeditation, such as sudden, impulsive acts driven by extreme recklessness.
Understanding the difference between these degrees often dictates defense strategies, plea negotiations, and jury instructions during a trial. Prosecutors carry the heavy burden of proving premeditation for first-degree charges, while defense teams frequently argue for reduced charges like manslaughter when malice is absent.
How Law Enforcement Uses 187 on the Radio
While civilians and media outlets often treat "187" as a generic police radio code, law enforcement dispatch practices vary by jurisdiction. In many California police departments, dispatchers use computer-aided dispatch (CAD) codes where "187" or "187 PC" serves as shorthand notation for a homicide call or an in-progress violent crime report.
Calls rarely begin with an immediate designation of murder. Typically, an incident starts as a severe assault or a medical emergency. Responding officers evaluate the scene, assess victim status, and instruct dispatchers to update the call classification if a fatality occurs or if evidence indicates a homicide.
Furthermore, police departments outside California rarely use "187" as an official departmental radio signal because their local state statutes use entirely different numbering systems—such as New York Penal Law 125.25 or Texas Penal Code Section 19.02. When officers or agencies outside the West Coast reference the number, they are almost always borrowing cultural shorthand rather than operational radio terminology.
Cultural Impact and Media Mythos
Few legal statutes achieve permanent residence in popular culture. Section 187 crossed over from legal text into mainstream awareness largely due to West Coast hip-hop culture in the late 1980s and 1990s, appearing in iconic tracks by artists like N.W.A and Snoop Dogg, as well as films.
Over decades, the number transformed from a bureaucratic legal citation into shorthand for lethal violence or total defeat in everyday slang. This cultural saturation created a wide gap between how everyday people use the phrase and how criminal defense attorneys and judges handle actual homicide cases in courtrooms.
Frequently Asked Questions
Is 187 a standard ten-code used by all police departments?
No. It is a specific section of the California Penal Code rather than a universal ten-code. Most police agencies outside California use entirely different numerical codes or plain-language dispatch protocols for homicides.
What is the difference between 187 and 664/187?
Section 187 covers completed murders. In California law, Section 664 designates criminal attempts, so a charge of 664/187 means attempted murder.
Does 187 require planning beforehand?
Not necessarily. While first-degree murder requires premeditation and deliberation, second-degree murder under the same statute requires malice aforethought, which can be established by a sudden, reckless act showing wanton disregard for human life without prior planning.
Can a murder charge be filed without a body?
Yes. Prosecutors can establish corpus delicti—the fact that a crime took place—using circumstantial evidence, forensic findings, digital trails, and witness testimony, even if human remains are never recovered.
