Sharon Tate (January 24, 1943 – August 9, 1969) was an American actress and model. During the 1960s, she appeared regularly in fashion magazines and played small television roles before appearing in several movies. In 1968 she married director Roman Polanski,
She was eight-and-a-half months pregnant with the couple's son when she was strangled and stabbed in the stomach and chest in her home. Very NSFW crime scene photo.
Four others, including the man that took this photo, were also murdered that night by a group known as the Manson Family on August 9, 1969.
Manson, an aspiring musician, had previously attempted to enter into a recording contract with record producer Terry Melcher (the son of actress/singer Doris Day) who was a previous renter of the house along with his girlfriend, actress Candice Bergen. Melcher snubbed Manson which left him disgruntled. In retaliation, Manson ordered the attack thinking that Melcher still owned the house, which had been rented to Polanski. Source.
To ensure they were noted as bungling idiots, they also stole $70 from one of their victims, Abigail Folger, heiress to the Folger coffee fortune.
