http://www.thisislondon.co.uk/standard/article-23493320-details/Family+of+Cambridge+student+killed+on+bike+hit+out+at+police/article.do The parents of a student killed while cycling are set to launch a private legal battle after claiming police failed to investigate his death properly. Vinnie Carta, 21, from Enfield, a third-year physics student at Cambridge University, was in collision with a car near his student digs as he rode to his part-time job as a children's maths tutor last November. He suffered massive head injuries, even though he was wearing a helmet, and died in hospital the following day, with his parents at his bedside. No charges were brought against the driver, who was found to have been doing 48mph inside a 60mph zone, and an inquest recorded a narrative verdict that Vinnie's death was an accident. But his parents, John, 51, and Anthea, 49, believe police and prosecutors accepted the driver's account of events without carrying out a thorough investigation or appealing widely enough for witnesses. They have employed a crash investigator to re-examine what happened and if he finds they could have a case are considering bringing a private prosecution against the driver. Mr Carta, a bus safety examiner, said: "Vinnie was an experienced cyclist. He was on his new bike, wearing a helmet and reflective clothing. He was on a well-lit route, which he took all the time. He knew what he was doing. "The driver has changed his story several times. We think he was in a rush to get home, thinking he was coming up to a 60mph road, and just didn't pay attention to the road. Vinnie was flipped in the air and landed on the car. "We're not looking for revenge. We're not vindictive. We just want the law to be applied. The police should have put up witness appeal boards but they said that could cause more accidents."
