John Rogers met killer Joanna Dennehy and lived to tell his story. While walking his dog near his home in Hereford, Dennehy set upon him with a knife stabbing him multiple times.

He spent weeks in hospital recovering from his wounds. He told the BBC's Ed Thomas that his abiding memory of the attack was how 'matter of fact' Dennehy had been throughout.
