A yoga teacher who murdered her lodger has today been jailed for life - as it emerged the victim previously killed his wife in front of their two young sons.
Landlord Dawn Lewis, 54, was told she would serve a minimum of 20 years for stabbing former police officer Glenn Richards, 61, to death at her home because she wanted to evict him.
The jury rejected her claim she acted in self-defence, as a judge described the murder as "pre-meditated".
