Looks back on 3 cases solved, because they were caught on camera.

In Tulsa, a beloved barber is caught in the crossfire of a long-standing gang rivalry. In Atlanta, a young man returns home during his lunchbreak and is killed by an armed burglar. In Dallas, an elderly woman opens her home to a man searching for his lost dog and pays a deadly price. In Miami, a mother down on her luck is killed at her storage unit after losing her job and her home.

Three of The First 48's most memorable cases featuring surveillance video are highlighted: in Cleveland, Ohio a robbery leaves an innocent man dead at the shop where he worked; in Dallas, an encounter on an elevator seals the shocking fate of a woman heading home for the day; and in Memphis, revenge is served in video surveillance that tells a misleading story.
