You've reached your conclusion, and now you're dilligently looking for a way to intellectually justify it. It's supposed to work in the reverse.
But I'm not jumping to any conclusions. That's what Greer has done all along and continues to do. Without there being an investigation, there can be no conclusions, except for his own, of course. But, I would like there to be something more than Greer's own word for what happened to Terri that night rather; I don't accept Greer's, he's not a police officer, an investigator, or a physician, even though he's put himself in their place.
