Three witnesses encounter a large creature while walking down a gravel road outside South Sioux City

15 September 1998 about 2:00am South Sioux City, Dakota County, Nebraska 3 witnesses

Account

Late at night three people walking on a gravel road smelled a strong foul odor. When they returned to the spot, a tall creature stood up from the roadside ditch, frightening them and causing them to flee. As they ran home they saw deer in a nearby cornfield and heard an extremely loud screeching-howling sound.
