The murder of Vivianne Ruiz occurred in Sydney, Australia. Her body was discovered in garbage bags on 28 December 1991 without any identification. A postmortem found strangulation to be the likely cause of death. Animal hairs were found on the body, and newspaper was stuffed inside her mouth.

On its removal, fingerprints in what appeared to be blood were present but could not be immediately identified. Investigators spent many weeks attempting to identify the victim. A sustained and significant media campaign was also conducted. Investigators were eventually contacted by a former associate of the victim who recognised her as Vivianne Ruiz.

Investigators discovered Ruiz had been in a relationship with Richard White, a convicted criminal with a history of assault and drug trafficking. He had grown to know Ruiz through her work as a prostitute and dancer in the Kings Cross nightclubs in Sydney. Investigators discovered White had left Australia shortly after Ruiz was found murdered. The fingerprint found on the newspaper Ruiz's killer had left in her throat was initially considered not to belong to White. Later testing demonstrated that a tonal reverse had occurred, a rare event where the valleys between fingerprint ridges transfer blood from the grooves of the fingerprint, as opposed to its ridges.

Investigators eventually tracked White to England, where he was living with relatives. A warrant was sought in England for his arrest, which was eventually made in Newcastle by local detectives and Scotland Yard. White returned to Australia to face trial for the murder. After two trials were aborted due to his abnormal conduct, he was eventually found guilty in 1996 and sentenced to the maximum jail term permitted in New South Wales at the time, which was fifteen years with a minimum of nine before being eligible for parole.
