Detectives have said they are no longer investigating the death of one of five hospital patients at the centre of a tampering probe.
The family of George Keep has been told he no longer forms part of the inquiry into the contamination of saline at Stepping Hill Hospital in Stockport, Greater Manchester.
Nurse Rebecca Leighton, 27, was remanded in custody on Saturday accused of three counts of criminal damage with intent to endanger life and three counts of criminal damage being reckless as to whether life was being endangered. The charges relate to the alleged tampering of medical products rather than named individuals.
Mr Keep, 84, of Cheadle, died on July 14 after being admitted to the hospital with a broken hip.
Detective Superintendent Simon Barraclough, who is leading the investigation, said: "We are working to set criteria to establish whether a death will form part of our investigation and this includes those people already named by us and the media. I can therefore confirm that, as a result of the processes we are undertaking, the death of George Keep will no longer form part of our investigation.
"We are working closely with highly experienced medical experts to scrutinise a person's medical history, the treatment received at the hospital, whether they came into contact with any contaminated products and whether or not any of these products have contributed to their death.
"This is an exceptionally complex and difficult process and one that cannot be rushed or completed quickly."
He said the previously announced deaths of Tracey Arden, Arnold Lancaster, Derek Weaver and Vera Pearson were undergoing the same review process and it was "not currently known" whether they will continue to form part of the investigation.
Stepping Hill employee Leighton, of Buxton Road, Heaviley, will next appear at Manchester Crown Court on August 1 for a preliminary hearing.
She is also accused of theft of medicine.
