MANISTEE, Mich. (AP) -- Authorities in Manistee are revisiting databases of missing children after workers at a western Michigan construction site found a human jawbone fragment in excavated dirt.
WGHN-AM in Grand Haven reports Friday that Manistee County's medical examiner said several teeth are intact and that the weathered bone fragment could have come from a female child.
The fragment was found Thursday.
The station also reports that authorities say they have no known open missing children cases.
The area where the fragment was found is a marina building and isn't believed to have been a burial ground. The area is about 95 miles northwest of Grand Rapids and will be examined next week for more bone fragments.
