One of the areas of the story I'm confused about is this:
Clint calls his mom after seeing silhouettes and hearing voices in the garage/carport. He states his mom says Holly should be at school. So then Clint says that Holly must be in the garage. How does Clint make that leap? Am I missing something here?
The recent interview with Clint is helpful. He hears voices outside that he does not recognize. He looks outside and sees silhouettes in the garage. He does not recognize them. He calls his mother. During his conversation with his mother, he looks outside again. He sees Holly with another person he incorrectly assumes is Drew. Seeing them, he assumes these were the persons he heard outside. And that these were the persons he had trouble identifying in the garage.
