Oklahoma City high school teacher Emma Smreker spends most of her weekends perusing used bookstores. One day she found a photostrip tucked between the pages, showing a man and a young girl. She was heartbroken that the sweet memory was lost, and it became her mission to reunite them with the photograph. Emma became a private investigator and posted the photo all over social media. More than a year later, a TV station in San Antonio aired a segment about it, and the man in the photo saw it.
