Una Crown murder: Suspect released 'due to insufficient evidence'
A man arrested on suspicion of murdering an elderly widow in her home has been released with no further action, police said.
The body of Una Crown, 86, was found at Magazine Lane in Wisbech, Cambridgeshire, on 13 January 2013. She had been stabbed and set on fire.
A 44-year-old man from Wisbech was arrested and bailed last November. He has now been released "due to insufficient evidence".
No-one has yet been charged.
Mrs Crown's burned body was discovered in the hallway of her bungalow by her niece's husband, John Payne, when he went to collect her for a day out.
She was last seen on Friday 11 January, but made a telephone call to a friend at about 17.00 GMT the following day.
Four people have so far been arrested and released by officers investigating her death.
A £10,000 Crimestoppers reward has been offered for information which leads to the arrest and conviction of those responsible for the murder.
