text:  CBS's Scott McFarlane in Washington. There was a deadly crash at a Deer Park, Long Island strip mall nail salon, as CBS New York's Carolyn Gusoff reports. We now know that four people inside that nail salon were killed. Nine people were injured, including the driver of a van, an out-of-control van, who witnesses are now telling us they saw speeding out of this parking lot, apparently trying to beat that light.
