Jeffrey Bratcher found?

Jeffrey Bratcher has been missing from Washington State since 1974. I know very little about his case, but he made the news today. Apparently eight sets of human remains have turned up in the University of Washington’s anthropology department, including the “partial skull of a juvenile. The remains may have been found by a resident who mailed the remains to the University of Washington from Bay Center, Wash., postmarked Sept. 9, 1980.” They think the skull might be Jeffrey’s. For the sake of his family I hope it is.

Who the hell, when they find bones, mails them to a university anthropology department? When you find human bones lying around you’re supposed to call the police. If they turn out to be ancient, that’s for the police to determine. How on earth did this happen?
