The owners of a Truro care home at the centre of a murder investigation have thanked police for their persistence.
A 40-year-old woman from Redruth was arrested on suspicion of murder in relation to a fire at the Rosewyn House care home more than five years ago.
Gladys Rowe, 96, died from respiratory problems caused by smoke inhalation a week after the fire on November 24, 2008.
Bill Dawes, who owns the care home jointly with Gregory Murrell, said: “We are pleased that progress has been made and we are grateful to the police for continuing to investigate this tragic event that took place in 2008.
“Our thoughts are with Gladys Rowe’s family at this time.”
At the end of the inquest in 2011 into Mrs Rowe’s death Cornwall Coroner Emma Carlyon recorded an open verdict and said: “We just don’t know what happened.”
Following the inquest Mr Dawes and Mr Murrell, together with manager Jenny Spargo, wrote to the chief constable of Devon and Cornwall Police to ask for further investigations to be carried out.
The woman, whose identity has not been released, was arrested on Wednesday on suspicion of murder and released on police bail.
Anyone with any information regarding the incident is asked to contact the police on 101.
