Two teenagers have sighting east of Seneca

Account

In the summer of 1979 the witness and a companion had pulled off the road east of Seneca when they heard a loud shrieking growl. A large human-like animal approached their vehicle in bounding steps. The witness shouted for the companion to get in, locked the doors, and fled at high speed, remaining frightened and avoiding that road afterward.
