No one, or at least no one who has come forward, saw a car; no one saw him walking, yet we know he did one or the other.
My opinion is he walked to and from the area. The homes within walking distance are key. A visitor, a friend, a house sitter, or a resident.
This monster didn't parachute in or materialize out of thin air. Someone saw him that day although right now they would say no, they only saw their neighbor, or a friend or their son. They would say that because that is what they believe to be true.
