Disappeared S03E12 - Lost Hero

The case of 32-year-old Florida firefighter Brandy Hall, whose truck was found submerged at the bottom of a pond after she went missing in August 2006. There were traces of her blood inside the vehicle and a year later her backpack - minus her gun - was found in a canal. The FBI reviewed the evidence and decided Hall had likely been murdered, but the mystery of her fate remains.
