Treachery: Not a Crime
Treachery is a generic aggravating circumstance to robbery with homicide although said crime is classified as a crime against property and a single and indivisible crime. xxx. Treachery is not an element of robbery with homicide.
Neither does it constitute a crime specially punishable by law nor is it included by the law in defining the crime of robbery with homicide and prescribing the penalty therefor. Treachery is likewise not inherent in the crime of robbery with homicide.
Hence, treachery should be considered as a generic aggravating circumstance in robbery with homicide for the imposition of the proper penalty for the crime. xxx. In fine, in the application of treachery as a generic aggravating circumstance to robbery with homicide, the law looks at the constituent crime of homicide which is a crime against persons and not at the constituent crime of robbery which is a crime against property. Treachery is applied to the constituent crime of “homicide” and not to the constituent crime of “robbery” of the special complex crime of robbery with homicide.
