Semi truck driver on I-70 observes a large ape-like creature in a field near Marshall

The witness was driving east on I-70 in Clark County, Illinois, in the morning when he saw a large black animal squatted in an agricultural field about 200-300 yards away with its back turned. The animal then moved toward the adjacent woods while stooped over on two feet with a crouched, squat-walking motion. The witness first thought of a bear but said the form looked ape-like and he had no other explanation.
