(AP) — Authorities say a man found in a wooded area in western Iowa is from Nebraska.

The state Division of Criminal Investigation says fingerprints submitted to a FBI database helped confirm the identity of 52-year-old Michael E. Gnirk, of Hoskins, Neb. A hunter found him on Saturday in a rural, wooded area a few miles southwest of Mondamin in Harrison County.

Authorities said in a news release Wednesday they’re continuing to investigate the case, and they’re trying to retrace Gnirk’s last few weeks and days. They’re looking for anyone who may have been in contact with him over the last three to six months.
