What action is denoted by the code 664-187?

The code 664-187 is commonly used in law enforcement to signify an attempt to commit murder. This code combines two elements: "664," which typically represents the attempt crime in California Penal Code, and "187," which denotes homicide. Therefore, when law enforcement officers receive a call or report associated with this code, it signals that there has been an attempted act of murder, indicating the seriousness of the situation and the need for immediate response and investigation.

Understanding this code is crucial for officers as it helps them prioritize resources and address life-threatening situations effectively. The other options, while relevant to emergency response scenarios, do not directly correlate with this specific code combination, making it clear that "attempt murder" is the accurate interpretation of 664-187.
