The Helter Skelter scenario is a theory put forward by Vincent Bugliosi, the lead prosecutor in the Tate–LaBianca murder trial. It is mostly based on the testimony of Paul Watkins, as a motive for the series of murders that were committed by the Manson Family in order to convict Charles Manson of conspiracy to commit murder. Bugliosi described his theory at trial and in his subsequent book "Helter Skelter: The True Story of the Manson Murders". According to Bugliosi's theory, Manson often spoke to the members of his "family" about Helter Skelter in the months leading up to the murders of Sharon Tate and Leno and Rosemary LaBianca in August 1969, an apocalyptic war arising from racial tensions between Black and White people. This involved reference to music of the Beatles, particularly songs from their self-titled 1968 double album (also known as the "White Album"), and the New Testament's Book of Revelation. Other scenarios besides Helter Skelter exist, with some writers, police detectives, attorneys involved with the case, and perpetrators identifying the Tate–La Bianca murders as either copycat killings, revenge for a bad drug deal, or a combination of two or all three.
