Spencer on Interstate 69 in Indiana. 5 people in the van died in the crash. Elizabeth Smith, Laurel Erb, Bradley Larson, and Monica Felver, were killed in the crash, as was a young blonde woman the coroner identified as Whitney Cerak. A similar looking woman who was in a coma was identified as Laura Van Ryn. The Van Ryn family cared for the woman they believed to be their daughter by keeping a bedside vigil for several weeks.
