What crime do Marcos and Chiz commit when they shoot Llanes without conspiracy?

In this scenario, when Marcos and Chiz shoot Llanes without prior conspiracy, the crime committed falls under murder. Murder is defined as the unlawful killing of another human being with malice aforethought, which includes intent to kill. The key aspect here is that the act of shooting Llanes demonstrates a clear intent to cause death or serious bodily harm, which characterizes the act as murder rather than other classifications of homicide.

While "homicide" itself is a broader term that encompasses all unlawful killings, including murder and manslaughter, the specific context of the shooting, particularly if it was intentional and premeditated, qualifies it as murder. Furthermore, offenses such as robbery and theft do not apply here since they involve the taking of property and not the intentional harm or killing of another individual.
