Law enforcement officers find and follow fresh snow tracks 33 miles NE of Moline

February 2018 a little after midnight Lyndon, Whiteside County, Illinois 3 witnesses

Account

After midnight an on-duty officer searching for a stolen snowmobile along a river heard loud crashing and heavy running in a treeline. He then found large human-like footprints in snow, with two larger sets and one smaller set, showing a long stride and signs of running. He and two deputies photographed the tracks and interpreted the trail as individuals scouting, pausing, and circling before leaving, then withdrew from the area.
