The stench of smoke was almost suffocating as fire investigator Craig Bain sifted through the charred remains of the bedroom looking for the spot where the blaze started.
Mrs Sanger's nephew Ray Broad said he had been through the house on Saturday cleaning things up and doing the washing. When the phone rang and he learned of what had happened he was absolutely gutted.
He said his aunt, who he has looked after for more than 16 years, was devastated by the news.

Mr Broad said fortunately the house was insured but he expected it could be some months before the house would be ready to live in again.
Crunching about in the burnt-out bedroom Mr Bain said he had investigated hundreds of fires but some were heart-breaking and this case was one of them.
"This is a lady who has been sick and just wants to come home to her familiar surroundings and some dirtbags have come in and stolen her stuff and set fire to hide the evidence but it didn't work," he said. "This tugs at the heartstrings."

Constable Gordon Romley said a forensic examination of the house had been completed along with a fire investigation.
