Una Crown

Una Crown was found in a pool of blood and with her clothing burnt in the hallway of her bungalow in 2013.

While her death was initially treated as an accident, a post-mortem examination later found she had been stabbed to death before her house was set on fire.

A £20,000 reward is being offered to try and solve the murder of a pensioner, 86, who was stabbed and set on fire 10 years ago.
