Identities of a human foot, bones found in Saginaw County remain mystery due to lab funding Updated 9:45 AM; Facebook Share SAGINAW COUNTY, MI — Investigators have suffered a setback in identifying a human foot found earlier this year along the Flint River in southern Saginaw County. The same complication is also keeping police from learning the identity of a set of human bones found in the county years ago. Sheriff William L. Federspiel said an unexpected cut in federal grant funding to a laboratory is what’s causing the two mysteries to remain unsolved. On Feb. 26, two teenagers who were fishing along the Flint River in the area of Seymour and East Sloan roads in Taymouth Township found the human foot. Federspiel described it as being in a lace-up work boot, size 10 ½. The sex, race, and approximate age of the foot’s person remain unknown.
