 Shoppers heard the crash and saw the aftermath. The front glass of the Hawaii Nail Salon on Grand Boulevard in Deer Park completely shattered by a van that hit and killed multiple people inside. And I saw everything, the glass, everything gone. And I saw them just taking people out. I was like, a car must have went through there. It's not yet clear if the four dead were customers or employees. Nine others, including the driver, were taken to hospitals.
