I am sorry to hear of your money being stolen, especially such a large amount. What kind of check did your sister want you to cash? Did you ever see it? How on earth could nephew kick it out of the car? Was it loose, in a walmart bag, in a bank envelope? I would check out the whole story of your sister needing YOU to cash a check. Does she not have an account? Couldn't she have gone to a check cashing place if she didn't have an account? It is entirely possible the kids took it, but I would start with the one who asked you to bring money in the first place. Was she hurting for money? If she suddenly pays bills she couldn't pay before, I would tell the police. I saw on one of the judge shows one time, where a person had a check from one of those "You have won a prize" places, and got a friend to cash it, and put the check in their account. The check was bad, and the friend was out thousands of dollars. The "friend" who asked her to cash it said she felt no responsibility for making it good. Some people don't have that sense of personal responsibility, but the judge had a word or two with the defendant about that. Anyway, sometimes those we least expect to mess up our lives, will. vc
