“ PARRICIDE (probably for Lat. patricidia, from pater, father, and cacdere, to slay) , strictly the murder of a parent; the term however has been extended to include the murder of any relative or of an ascendant by a descendant. The first Roman law against parricide was that of the Lex Cornelia de sicariis et veneficis (c. 81 B.C.) , which enacted that the murderer of a parent should be sewed up in a sack and thrown into the sea, and provided other punishments for the killing of near relatives. ”
