Guest4 and mean words, haha.. come on Jenny, there is no way to tell the credibility of this kind of posting. Anyway, you sound real. So called his son, who has not called her for 2 years..hmm may be he is in truble otherwise why is not he in touch. It is unlikly that this kind of person is listed in directory. Do you know his wife's name? or is it possible to find out who had he married with from county or city clerk recorder and search through her name? If you really really want to help, may be you should hire a private ditective.Anyway, you are at right place and getting some feedbacks. You should focus in Sacramento area and I guess you don't live there, otherwise it could be helpful to meet and ask around some permanet Nepalese over there.
