Ms White, who had been working as a sex worker, was found stabbed more than 50 times in a flat in Cardiff docklands.
Detectives originally said they were hunting a white suspect, but five black and mixed-race men were arrested and charged with her murder.
The included Tony Paris, Yusef Abdullahi and Stephen Miller, who were all wrongfully convicted of murder in 1990.
Their convictions were later quashed by the Court of Appeal.
After advances in DNA technology, Gafoor was caught and jailed for life with a minimum term of 13 years.
A police corruption trial surrounding the case later collapsed.
In January 2023, Gafoor was granted day release from prison but, despite several applications, he has never been released on parole.
