Nearly a dozen years after Allison Foy was last seen alive leaving a Wilmington, North Carolina, bar and a decade after her skeletal remains were found a mile from that night club, her death is still a mystery. Foy, who was 34, asked a bar worker to call a taxi to take her home that July 2006 evening but there is a suspicion that the cab she stepped into was not the one that was called. Investigators concluded that Foy was stabbed 40 times and thrown into a ditch near where the remains of another woman was found dead. Nancy Grace explores this murder mystery with Foy's sister Lisa Valentino and Cold Case Research Institute director Sheryl McCollum..
