APPANOOSE COUNTY – Authorities investigating the slaying of a Cedar Falls hunter in Appanoose County said they believe the immediate danger to the public has passed.

In recent days, investigators have collected evidence from the area around Lake Rathbun where the body of 31-year-old Curtis Ross was found over the weekend.

Still, with the advent of the first shotgun deer season approaching, officials with the Iowa Division of Criminal Investigation are asking hunters and others passing through the area to notify authorities of any additional evidence they come across.

“If any hunters find anything that is out of place they are asked to not touch the items and to contact law enforcement to come and look at the items,” DCI officials said in a prepared statement released Thursday. “Law Enforcement would also like to remind the public to always be alert of their surroundings and to use civility, respect and sportsmanship with fellow hunters and landowners.”

The results of an autopsy are pending laboratory tests, but DCI officials said they are treating the death as a homicide.

The public is being asked for help in the investigation, and anyone with information is asked to call the Appanoose County Law Enforcement Center at (641) 437-7100.
