Rosemary LaBianca wurde am 15 Dezember 1929 in Mexiko geboren. Sie war mit Leno LaBianca und Frank Struthers verheiratet. Sie starb am 10 August 1969 in Los Angeles, California, USA.
Rosemary's early life is somewhat of a mystery. Her parents either abandoned her or died prematurely. She grew up in an Arizona orphanage until the age of twelve, when a California family by the name of Harmon adopted her.
