A familicide is a type of murder or murder–suicide in which an individual kills multiple close family members (children, spouses, siblings, or parents) in quick succession. In half the cases, the killer lastly kills themselves in a murder–suicide. If only the parents are killed, the case may also be referred to as a parricide. Where all members of a family are killed, the crime may be referred to as family annihilation.
