Samantha Novak was found face-down in a river near the southwest English city of Bristol in 1985. A coroner's report said the 21-year-old tumbled off the riverbank after a night out with friends.
Avon and Somerset Police said Wednesday the force is making fresh inquiries into the case after the mother of a convicted killer's victim gave police a new lead.
Police said the mother of Penny Beale - who was killed by her partner Michael Moffat in 2001 - told police her daughter had said Moffat was involved in the murder of Novak.
The 73-year-old Bassey has maintained that Novak's death was not an accident or suicide.
