Ari Squire ran a successful construction and remodeling company that enabled him to indulge in a pastime popular at fairs and racetracks: competing to see whose diesel truck is fastest and can pull the heaviest load. He built a huge garage on his property in Lake Barrington so he had room to tinker with the big vehicles. One day in February 2008 an accident in that garage resulted in his death but was it really an accident?
