@maone Even though you feel he may have been planning this and that he may have felt he was doing this to protect others, I would file a missing persons report. If you have anything that they can get DNA from and keep it in their files, or anything with his fingerprints, all of this can be kept in a national or even International database. If his fingerprints or DNA come up anywhere they can be run through the data base and you may have some additional answers of what is going on. I know that this seems very clinical and dry, but it would help give closure. Like all of the others here I hope that you continue to keep posting and letting us know how you are doing.
