How does the common law classify killings under felonious homicide?+
At common law, felonious homicide encompasses any unlawful killing. It is subdivided into murder when malice aforethought is present and manslaughter when the killing is unlawful but lacks malice.
Can a death during a non-qualifying felony still be felonious homicide?+
Yes. When a death occurs during a felony that does not support felony murder, the killing is at least involuntary manslaughter if the death is a foreseeable consequence of the felony.
Does felonious homicide require proof of malice aforethought?+
No. Felonious homicide is the broad category of unlawful killings. Malice aforethought is required only for the murder subdivision. Manslaughter within the category lacks malice.
