As shocking as it might seem, there are over 100,000 missing person cases active in the United States this very second. While the majority of them are eventually found, there is a large percentage of those who have been gone for years. The police extended their investigations as much as they could, and they reached the very end because there was no new information. Finally, those cases simply turn cold.Missing person cases are particularly difficult for both families and friends. All of them are left without answers about what happened to their loved one, and they are constantly waiting for a break in the case, hoping they will have closure. The Daniels family lived through all of this in the summer of 2013 when their daughter Tiffany went missing one afternoon. It is one of the most perplexing cases in the history of Pensacola, Florida that still puzzles the investigators.
