An epilepsy sufferer who continued driving despite his condition killed a passenger after he had a seizure at the wheel.Peter Murdoch was diagnosed with epilepsy around 30 years ago but never told the DVLA.He was driving with his wife and two friends when he failed to stop at a junction onto the A592 in Bowness, Cumbria, narrowly missed two cyclists and ploughed into a wall in June last year.Passenger Elizabeth Thompson, 68, from Marlow, Buckinghamshire, died instantly of multiple injuries, an inquest heard.She and husband Garth had been visiting friends Peter and Dorothy, of Main Street, Staveley, Cumbria.The couple did not know about Mr Murdoch's epilepsy.The inquest heard the four were travelling along Glebe Road, Bowness when they approached the 'give way' junction leading onto the A592 on 10 June last year.But Mr Murdoch failed to stop or turn and instead carried straight on, narrowly missing two cyclists before hitting a wall straight ahead.Garth Thompson told the inquest that he had noticed a change in his friend's behaviour prior to the crash.He said: 'I was aware that he had become somewhat non-responsive. He accelerated and was driving faster than you would normally think appropriate but then slowed down and all seemed to be well again. Then he accelerated inappropriately when he came up to the junction.'In reference to his epilepsy, Mr Murdoch told the court: 'I obviously should have contacted the DVLA but I do not remember anyone ever mentioning it.'Mrs Murdoch told the inquest at South Lakeland Magistrates Court: 'The epilepsy goes back to the 1980s, and was dealt with by medication, after which his seizures were rare.'She mentioned an occasion where he was playing squash and blacked out, leading to an overnight stay in hospital.PC Craig Irving, a collision investigator for Cumbria Police, said all the evidence pointed to Mr Murdoch having some sort of seizure before the tragedy.A spokesman for Cumbria Police said that after discussion with the CPS and medical experts a decision taken not to prosecute Mr Murdoch.Ian Smith, South and East Cumbria coroner, said the accident highlights the potential danger of taking to the wheel after being diagnosed with conditions such as epilepsy.He recorded a verdict of accidental death and said he would be writing to the DVLA and Department of Transport.'I will write about the apparent lack of importance put on notifying the DVLA about medical conditions,' he said.'I think doctors ought to take an active stance in relation to anyone who may have a problem and should also be required to notify the DVLA.'
