Sororicide

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Sororicide (from Latin soror "sister" + -cide, from caedere "to cut, to kill") is the act of killing one's own sister. There are a number of examples of sororicide and fratricide (the killing of one's brother) in adolescents, even pre-adolescents, where sibling rivalry and resulting physical aggression can get out of hand and lead to the death of one of them, particularly when a potent weapon is available or one is significantly older than the other and misjudges his/her own strength. Sororicide is similar to child murder (the killing of an unrelated child), infanticide (killing of an infant under the age of one year), filicide (the killing of a child by his or her parent), and patricide and matricide (the killing of a father or mother respectively by his or her child).
