Because of the blood, my take on this is that very soon after the perp meets Holly in the garage/carport..he has committed two felonies, criminal trespass, and assualt...maybe the question is, what caused the perp to add on kidnapping and possibly murder..was it that Holly would recognize him?
well just being on someone's property may/may not be a huge criminal issue. So if Holly opened up the back door and saw some guy in the back yard, and he just ran off... he probably would not be charged with much, or anything.
I do not think things "escalated" just randomly that this was, somehow, planned and thought out (for exactly what purpose I am not sure). I do think the suspect intended to go inside the house (he did to some extent by taking Holly from outside into the garage). And perhaps Clint and the dog spooked him. I think he did not know that Clint was home.
Again if it were to just silence a witness why not kill them on the spot. And since the suspect was dressed head to toe in camo, he could have also had a face mask or cover as to not be identified. After all Clint did not readily identify the suspect and only assumed it was Drew.
All I can do is reconstruct actual events based on the few known details, but we do not have motive, intent, ultimate goal, etc.
1) Holly went outside to her car, parked in the open car port behind the house.
2) Something happened and she screamed and was perhaps struck or hit.
3) Neighbor heard the screams. Dog barking wakes Clint up. Suspect and Holly apparently talked since Clint heard voices outside (in the yard)
4) Suspect and Holly entered the enclosed garage (I assume via the door Holly exited the house to go to her car, or a door near the carport)
5) Clint sees silhouettes in the garage and later finds blood in that spot
6) Clint goes away from garage area of the house, calls his mom
7) Clint sees Holly and suspect walking northward in the yard
8) Clint gets a gun and goes outside
9) Neighbor arrives on the scene and Clint talks to neighbor, does not pursue suspect
10) Law enforcement arrives and reportedly does not immediately pursue suspect
