(Butler County, OH)--Two young Union County residents were killed in a crash Thursday on Todd Road in Butler County, just outside Hueston Woods. Three people were headed there to go sledding. The driver, a Union County senior, was taken to McCullough-Hyde Hospital and will be okay. Investigators say speed was a likely factor. "People do speed through here a lot. They underestimate what those hills can do," said Diana Phillips, who lives on Todd Road. The names of the victims were not immediately released.
