Memory of seeing something chimp-like in the trees and being chased out of the woods near Brereton

12 July 1969 late afternoon Brereton And Norris, Fulton County, Illinois 3 witnesses

Account

In July 1969 the witness and two younger brothers were on bikes on a bridge over a creek when they watched a 4-foot dark brown young animal play in a tree about 300 feet away for five minutes. The witness felt overwhelming terror without seeing a threat and led the brothers away. While they rode about a half mile home, a brother reported a strange hairy man chasing them, which the witness interpreted as an adult protecting its young.
