Rosemary LaBianca was an American woman who became a victim of a notorious crime in 1969. She was married to Leno LaBianca, and together they owned a grocery store in Los Angeles. On the night of August 10, 1969, both Rosemary and Leno were brutally murdered in their home by members of the Manson Family, a cult led by Charles Manson. The LaBianca murders occurred just one day after the infamous Tate murders, which involved the killing of actress Sharon Tate and others.
