Cass Elliot (born Ellen Naomi Cohen; September 19, 1941 – July 29, 1974),Cass Elliot, also known as Mama Cass, was an American singer and actress, best known as a member of The Mamas & The Papas.
Cass Elliot, age 32, died in her sleep at the London flat where she was staying. According to forensic pathologist Keith Simpson, who conducted her autopsy, her death was due to heart failure. A drug screen that was part of the forensic autopsy revealed there were no drugs in her system. Elliot died in Flat 12, 9 Curzon Place (later Curzon Square), Shepherd Market, Mayfair, London, which was on loan from singer-songwriter Harry Nilsson. Four years later, The Who's drummer Keith Moon died in the same room, also aged 32 years. Elliot was buried in Mount Sinai Memorial Park Cemetery in Los Angeles, California.
An oft-repeated urban legend is that Elliot choked to death on a ham sándwich. The story spread soon after the discovery of her body and was based on speculation in the initial media coverage. A 2014 article in Haaretz identified the person who started the false rumor as follows: "Unfortunately, the first doctor [in London] who examined her speculated to the press about the cause of death, and that’s the version that stuck." An autopsy had not been performed when the physician was quoted, and London police told reporters that a partially eaten sandwich found in her room might have been relevant to the cause of death. The post-mortem found that Elliot had died of heart failure, and no food was present in her windpipe, yet the false story has persisted ever since
