You can try to call the Postal service and request a case be filed. They should give you a number and call you back with information within 24 hours. KEEP ON TOP of them if they don't call you back and make sure you keep your Case number. Sometimes they will go out of their way to find it. I have had it happen to me before with things I have shipped. Sometimes they find them, sometimes they do not. With insurance there is not much you can do. Much luck to you, I really hope she gets found!!!!
