The Gatton Murders, also known as the Gatton Tragedy, the Gatton Mystery and the Murphy Murders, is the name given to an unsolved triple homicide that occurred 1.5 miles (2.4 km) from the town of Gatton, Queensland Colony, in present-day Australia. Michael Murphy, aged 29, and his younger sisters, Honora (Norah), aged 27, and Theresa (Ellen), aged 18, were murdered between 10pm and 4am on 26–27 December 1898, while returning home from a cancelled dance. All three siblings had been bludgeoned; in addition, Michael had been shot and Norah strangled.
