Errol Musk, the father of tech billionaire Elon Musk, has been accused of multiple instances of sexual abuse against his other children and stepchildren, according to a bombshell report. The claims against the 79-year-old span decades and involve alleged incidents involving five of his children and stepchildren in South Africa and California, The New York Times reported. One of the alleged victims was his stepdaughter, who went on to have at least one child with Errol Musk, whom he is also alleged to have abused. The allegations involving the stepdaughter are that Errol allegedly touched her inappropriately when she was four-years-old at the family's Pretoria home in 1993.
