A photographer captured the moment of a lifetime for one couple, then set out to find them. Julio Salazar snapped a photo of a couple getting engaged in Chicago's Millennium Park while he was setting up for another shoot. When he saw the man drop to one knee, he quickly grabbed his camera and started shooting. Once he realized he got a good shot, he looked up to find the couple, but they were gone. He posted the picture on Facebook asking people to help identify them. #InsideEdition
