First responders are searching the Kokosing River after a teenage boy was reported missing Tuesday. According to Knox County 911 dispatchers, Sheriff Dave Shaffer said crews were searching for the 15-year-old from Columbus in the area of Honey Run Falls. Sheriff David Shaffer said the teen was in the area with two other teens and an adult when the incident happened. The search continued Tuesday for more than five hours before it was called off for the night. This is the second search of the river in a week. Last Friday, first responders found the body of Mark Booth, who went missing Thursday while tubing on the Kokosing River near the Caves Campground.
