An American playboy has been charged in connection with the deaths of two British businessmen - including one from Warwickshire - who were mown down in a hit-and-run crash.

Kenneth Watkinson, 48, of Leamington Spa, and Craig Elford, 39, of Ratley, Oxfordshire, were both killed as they walked to their ocean-front hotel in Fort Lauderdale, Florida, on February 13 last year.

A white Porsche GT2 owned by 35-year-old Ryan LeVin, the heir to a jewellery empire, mounted the kerb, hitting the two Britons before speeding off.

Jonathan Pavsner, who represents Mr Watkinson's widow Kirsty and their three children, said the local state attorney's office had charged LeVin with two counts of vehicular homicide and two counts of leaving the scene of an accident causing death. Each of the vehicular homicide charges could carry up to 15 years in prison.

He added that LeVin, who has a history of motoring offences and drug abuse, attempted to claim a friend, Derek W Cook, had been driving the performance car when the accident happened.

But police stopped the car only 12 minutes before the accident for driving away quickly from a green light and because of a loud exhaust, and LeVin had been at the wheel at that point.

Just moments before the crash, the Porsche and a BMW belonging to Cook were caught on camera speeding along the road before the Porsche lost control. The Porsche was later found abandoned after police failed to stop the damaged car as it drove at speeds in excess of 100mph.

Cook has been charged with being an accessory after the fact and aggravated fleeing and eluding. He is free on 8,500 dollars bail.

At the time of the crash, LeVin, who has a record of more than 50 traffic offences, was on probation for a high-speed police chase in Chicago that left one police officer and two drivers hurt.

He also served six months in prison last year for violating his probation by failing to complete a drug treatment programme.

Mr Watkinson and Mr Elford ran a pharmaceutical business, Ingala Healthcare, and were in America to recruit employees.

Mr Watkinson was living in Harbury, near Leamington Spa, with his second wife Kirsty and son Max, now aged five.

He also leaves two children from his first marriage, Jonathan, 20, and Stephanie, 17. Mr Elford was the father of a newborn baby girl at the time of the accident. His two daughters are now aged three and one.
