Looks back at three cases solved, because they were caught on camera. In Tulsa, multiple cameras help crack open a case. Then, in Atlanta, a key witness provides a crucial lead after seeing surveillance footage of the suspect on the news. And in another Tulsa case, detectives watch in horror as a hit and run driver targets homeless people. They race to stop him before he kills again.

In Kansas City, when detectives discovered two women in an abandoned garage, they had no idea how big the case would turn out to be. In Dallas, investigators used a surprising clue to bring their killers to justice. And in Miami, one marina is linked to two murders that share a shocking connection.
