Stepping Hill death of Vera Pearson ruled out of inquiry
Detectives investigating the sabotage of saline at Stepping Hill Hospital said the death of an 84-year-old woman is no longer part of their inquiry.
Vera Pearson died at the Stockport hospital on 14 July, and her death was referred to detectives by a coroner who had concerns about her low blood sugar.
An inquiry is being continued into three other deaths at the hospital.
Stepping Hill nurse Rebecca Leighton, 27, has been charged with criminal damage with intent to endanger life.
Police earlier ruled out the death of George Keep, 84, of Cheadle, which had also been linked to the inquiry.
The deaths of Tracey Arden, 44, of Heaviley, Arnold Lancaster, 71, of Romiley, and Derek Weaver, 83, from Stockport, who died at the hospital in July are still being investigated.
Low blood sugar
The alarm was raised when a higher than normal number of patients were reported to have low blood sugar levels.
Rebecca Leighton, of Buxton Road, Heaviley, has been charged with three counts of criminal damage with intent to endanger life and three counts of being reckless as to whether life was being endangered.
The charges relate to the alleged tampering of saline ampoules, saline bags and medical products. She is also accused of theft of medicines.
She is on remand at Styal Prison in Cheshire and is due to enter a plea at Manchester Crown Court on 17 October.
A provisional trial date of 28 February 2012 has been set.
