I know about the witness hearing a scream. But what is this about a car speeding away? The witness said it sounded like a Bobcat scream. I think Dennis got lost and died of exposure. A child's skull was found years later in Tremont Big Hollow by a Guinsing Hunter, who did not originally report it because he had been in the park illegally, He told the head ranger who went to investigate and found nothing. The investigation check was in the mid 80's.Are you referring to the car that sped away after Harold Key heard a scream and witnessed a man hiding in the bushes?
Because no other children at that time had gone missing in the Smokies. I believe the skull was Dennis' The terrain and landscaping would be too difficult and inconvenient for a kidnapping.
