My first thought was that her boss or bosses was involved, primarily because it seems odd for a small business like this to employ two high-school aged girls. I could understand if it was a yogurt shop but how much work was there? Of course, I am clueless as to the particulars. Most teens who smoke like she did (I was one) wouldn't leave cigarettes behind, not even for a quick errand. It is more likely she came back and was interrupted/abducted at work. It's creepy, too, that Unsolved Mysteries has that many requests!
