article: Ian Walters, 51, allegedly killed his wife Tracy by deliberately driving their truck into a tree at 84mph . A church treasurer accused of murdering his wife deliberately veered his 4x4 off the M1 causing it to explode as it hit trees, a court heard today. Leicester Crown Court was told that two dogs and suitcases were also thrown out of the pick-up truck being driven by Ian Walters as it crashed into a line of trees near Markfield, Leicestershire. Yesterday the court was told that his wife, Tracy Walters, died after making a flurry of calls to police about sex-obsessed husband in the days leading up to the M1 crash, including one that morning. Prosecutors allege that Walters, a driving test examiner, deliberately steered his Mitsubishi L200 off the motorway after his wife said she wanted a divorce and made allegations of domestic abuse. Walters, 51, denies the murder of his wife, who died in hospital two days after the high-speed crash. A jury of nine women and three men was told yesterday that Walters, of  Swindon, was returning home with his wife from a 'make-or-break' week away in North Yorkshire which ended in an argument. Giving evidence to the second day of Walters' trial, several witnesses described how passing motorists went to aid the couple, both trapped in the wreckage of the 4x4. The first witness, Robin Goss, told jurors the driver of the pick-up appeared to have made a 'conscious, deliberate' decision to steer towards the hard shoulder. Mr Goss, a 39-year-old training consultant from Buckinghamshire, told jurors he was up to 150 metres behind the L200, doing around 70mph in the inside lane. 'Everything was normal,' Mr Goss told the court. 'Then all of a sudden I saw this car just swerve violently across to the left. 'It completely disappeared and I remember looking into the hard shoulder. Then I saw what looked like a little explosion. 'Bits of tree and bits of plastic came out in front of me. When I saw the dogs, I started to put together what had happened.' Child protection worker Gary Donald, who was driving a Kia Picanto on the southbound carriageway, also gave evidence to the court about the crash on March 21 last year. He told jurors he saw the pick-up veer sharply from right to left - performing 'almost a straight turn' - and move towards a line of trees. The couple, who were said to have had a 'troubled' relationship, had married in Cyprus in 2012 but their relationship is alleged to have become abusive soon afterwards, jurors heard . 'The canopy of all the trees shook - I would use the word 'imploded' - and there was luggage, bits of car, and parts of tree flying into the air,' Mr Donald said. Under questioning from defence QC Christopher Millington, Mr Donald agreed that time-lapse CCTV footage of the L200 showed a 'rather less dramatic' veer than he had described to the court. Witness Steven Prince, a passenger in a Range Rover which stopped at the scene, told how he attempted to reassure Mrs Walters before she was cut free. Giving his recollection on the aftermath of the crash, Mr Prince told the jury panel he did not witness the moment of impact but had seen a cloud of dust. 'I looked left and I saw two dogs out where they shouldn't be and I saw the car that was already in the tree.' After the crash, the metalwork of the vehicle had to be 'unpeeled' from around Mrs Walters by emergency crews, the court was told . The Mitsubishi L200 veered onto an embankment near junction 22 of the southbound carriageway in March last year. Pictured: Emergency services at the scene of the crash . Prosecutors allege that Walters, a driving test examiner, deliberately steered his Mitsubishi L200 off the motorway after his wife said she wanted a divorce and made allegations of domestic abuse . After getting out of his mother's car, Mr Prince said, he ran along the hard shoulder towards the crashed vehicle. 'The car was a hell of a mess,' Mr Prince added. 'I didn't bother looking at the driver's side because I thought whoever was in there was going to be squashed.' The court heard that the witness then made his way to the passenger side of the vehicle, where he saw a hand sticking out of the wreckage. He said: 'She said she was dying. I told her she would be alright and that I wasn't going anywhere, just to calm her down and make her feel at ease as much as I could.' Prosecutor Charles Miskin QC asked Mr Prince if Mrs Walters, who was aged 48, had said anything else. 'No, other than that she couldn't breathe,' Mr Prince replied. 'She kept on telling me that and she kept on saying that she was dying.' The trial, which may last for up to a month, was adjourned until next week.
