MARSHALL COUNTY, Iowa (KCRG) - On August 10th at approximately 4:00 pm, deputies with the Marshall County Sheriff’s Office were directed to a remote area in the Iowa river where a possible human lower jawbone was discovered by Marshall County Conservation staff during a biological and wildlife survey.

Officials say that the jawbone was intact but deteriorated, indicating that it was several years old. Investigators conducted a more thorough search of the area and located three additional potential human bones.
