Detectives are reopening the investigation into the murder of a pensioner seven years ago.
Miss Freeman died from head injuries
Retired nurse Elsie "Viva" Freeman, 76, was discovered dead in a bedroom at her home in Impington near Cambridge on 7 March, 1998.
Her hands and feet were bound and she had been beaten. Police believe she was killed when a burglary went wrong.
Cambridgeshire Police said the case was being reopened following a new lead involving DNA evidence.
Det Supt David Hankins said: "A line of inquiry has been divulged to us which has led detectives to reopen the case.
"A major investigation was carried out following Miss Freeman's death and as a result of this new line of inquiry a full review is now being carried out."
Police believe Miss Freeman's house, which was hidden from the road by trees and shrubs, had been broken into from a side window.
A post-mortem examination showed the 76-year-old died from head injuries.
Police said the investigation proved difficult because Miss Freeman was a recluse and few people knew her well.
Despite taking almost 700 statements by the second anniversary of the murder detectives were unable to identify the killer.
