Family and friends spent much of the day Sunday searching for Timothy Tim Todd Fritch, who has been missing from the Humboldt area since Saturday evening.
Fritch, 41, was last seen at Wide Open Speed Park, which was hosting a demolition derby that evening.
An acquaintance used a Find My Phone app later in the evening in an attempt to find Fritch, which placed him first near Neosho Falls, then again near Le Roy along K-58 highway. His vehicle and personal belongings were found near the Neosho River bridge on the edge of Neosho Falls, but his cell phone was missing.
Fritchs sister, Cora Finley, detailed the subsequent search through Sunday, which followed the Neosho River between Neosho Falls and Iola. Searchers were on foot or all-terrain vehicles, while others were on watercraft to traverse the river.
Finley said officers suspect Fritch may have been picked up by someone.
Another search upriver from Neosho Falls was planned for today.
Fritch is about 5 feet, 11 inches tall and weighs 275 pounds. He has brown hair, which is shaved. He has hazel eyes and was last seen wearing a light gray or white T-shirt and blue jeans.
Anyone with information regarding Fritchs whereabouts is encouraged to call the Woodson County Sheriffs Department at (620) 625-8640.
