Una Crown murder: Two arrested men released without charge
Two men arrested on suspicion of murdering an 86-year-old widow in Cambridgeshire have been released.
The body of Una Crown was found stabbed and burned at her Magazine Lane home in Wisbech on 13 January 2013.
A 40-year-old man from March and a 36-year-old from Wisbech arrested on suspicion of her murder on 17 June will face no further action, police said.
A new team of detectives was brought in to investigate the case in May, however no-one has yet been charged.
Mrs Crown's 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.
He and his wife Judy were initially told by police the death was accidental and were allowed to return to the house to sort through her belongings.
A murder investigation began three days later after a post-mortem examination found Mrs Crown had been repeatedly stabbed.
Police believe her body was set alight in an attempt to cover up the killing.
A £10,000 Crimestoppers reward has been offered for information leading to the arrest and conviction of those responsible for the murder.
