Archibald Beattie McCafferty (1949 - 2024) was born in Glasgow and emigrated to Australia at the age of ten. In 1973, after his six-week-old son died, he told police the boy's voice had instructed him that the child would be born again if seven people were killed. He and a small group of followers killed three men in New South Wales: George Anson, 50, Ronald Neil Cox, 42, and Evangelos Kollias, 24. The Australian press called him Mad Dog and compared the group to the Manson family.
He was sentenced to three life terms in 1974. While held at Tamworth Correctional Centre he killed a fellow inmate, Edward James Lloyd; he denied that killing but received a further fourteen years for it. He later gave evidence about corrupt prison officers.
He was released on parole and deported to Scotland on May 1, 1997, having served 23 years. He changed his name to James Lok, worked as a painter and then a toymaker, and remained out of serious trouble; a later trip to New Zealand ended in deportation for failing to declare his record. He died in Edinburgh in 2024, aged 74, after a fall, while suffering from COVID-19, COPD, pneumonia and acute kidney failure. His death was not reported publicly until July 2025.
Three of the four killings were committed in a single 1973 sequence with accomplices; the fourth was in custody nine years later.
