Joanna Dennehy stab victim John Rogers dies 21 November 2014 Last updated at 20:15 John Rogers speaking in February about the attack A man who was stabbed 40 times by serial killer Joanna Dennehy has died. John Rogers was one of two men attacked while they walked their dogs in Hereford in April 2013. At the time, Dennehy, who last year admitted killing three men in Cambridgeshire, was on the run from police. She was given a whole-life jail term in February. West Mercia Police said they were not connecting Mr Rogers' death with the murder investigation. Changed forever A spokesperson for the force said they were not planning to pursue further inquiries, but passed their condolences on to his family. Speaking in February, Mr Rogers, 57, said he had been "changed forever" by the attack. "It's changed my outlook - I try to make the best of every day," he said. I made the decision I was not going to let this woman ruin my life. He was walking his dog along a cycle path in the Golden Post area of Hereford when he was repeatedly stabbed in the back and chest by Dennehy. She left him lying on the ground and a passing woman called for help. He spent 10 days in hospital and underwent surgery to both of his lungs, which had been punctured. Dennehy pleaded guilty to two charges of attempted murder over the attacks on Mr Rogers and fellow dog walker Robin Bereza. She also admitted three counts of murder and preventing the lawful and decent burial of those victims.
