I thought it a little odd that Holly's father would leave out the brother when saying he thought it was someone local and knew the schedules of mother, father and Holly. Could be several reasons. Maybe brother is not employed right now and doesn't leave at regular times. Just made me curious.
Never know, but brother may work a later shift somewhere, evenings, graveyard, may be in college (class times vary depending on major), or maybe unemployed. I don't think it's odd that father left this out, if Clint is unemployed, or works a different shift. Maybe Clint was normally asleep at that hour. Truly don't know as we are all speculating, but, Clint is ruled out obviously based on purported scream and 911 calls, and due to time factor. I personally think the reason he was cleared so soon is because of the reported scream. Think about it, no way could he have been responsible for that scream, and subsequent reporting of it to LE. The fact that he made a 911 call before, after, or within a small time frame of this call, (moo, after the first call by neighbor), only reinforces his innocence. He probably looked out the window that morning, as I do and lots of people do cause you want to see what kind of a day it will be, is it pretty, cloudy, rain on the horizen. By the grace of the powers we believe in or don't understand, his moment of looking corresponded with Holly being led into the woods by BF. Sometime after that, not too long of a timeframe, neighbor hears scream, probably closer to neighbors house than Bobo's house, Clint goes outside (unrelated to scream cause he probably did'nt hear it) and says WTF, Holly's car is still here and there is blood and she is suppose to be on way to school, test day. He tries Holly's phone, no answer, calls BF's phone, he is at work. So he at that that time becomes very concerned. Calls Mom, then 911. Read where Mom literally screamed in anguish and fear at the school that morning. All just my opinion, sorry for typos, but this just makes most sense to me.
