Ok perhaps this will help with understanding what happened and where.
I made this sketch based on several ground level and aerial views of the house, and also from some discussions here before with a verified local who was familiar with the floor plan and interior layout to a general extent.
1) open air carport at the back of the house
2) door from back of house to car port (assumption based on how most car
ports have a door to the house. The door could be by the small patio above
the carport, as well.)
3) front door to the house
4) another door to the house
5) above ground pool you can not see over
6) driveway to Swan Johnson road
7) garage with doors walled over and converted to living space. No doors
visible, just windows on three sides, based on photos. A verified regular
here confirmed this was a remodeled garage now used as living or interior
house space, but was still called "the garage" by the Bobos.
8) where I think the Kitchen windows would be
9) unknown area of the house. Since the garage and/or house was
remodeled, I am unsure what this area is like.
NOTE Areas 1-7-9 could all be construed to be the garage, I suppose
A and B - hypothetical divider walls. I feel there is some connection between the Garage and Carport. Perhaps this area is used for utilities like washing machine, storage, etc. It may very well be that 7 and 9 are one large room and that Clint looked through some opening along A and saw Holly and the suspect in this "garage" area, Clint stated very clearly the Garage was attached to the house and they were IN the Garage and blood was found IN the Garage.
C old front of the garage that would have had opening garage doors at one time but now has just a window. The shape of the driveway matches this location too. There is a large concrete stoop in front of the front door of the house that seems to have been added perhaps when the garage was remodelled. Perhaps 4) the second door, was the original front door?
Based on aerial photos you can see a dirt trail around the top end of the house from the edge of the driveway, around the pool, and back to the car port. There is at least one photo showing a car parked in front of but not under the car port.
I assume based on the JVM interview that, perhaps, Clint was in the upper area of the house and heard the voices somewhere perhaps around the back patio or carport area. Did the suspect accost Holly at her car, where she dropped a Coke can? Did the suspect then force Holly back into the garage/house?
I think at this point is when the suspect struck or hurt Holly somehow, causing the blood loss. This is when Clint saw them kneeling down. It may be also that the suspect heard the barking dog and/or Clint and was spooked. Based on Clint's statements it did not seem to be brightly lit and could the suspect have shhhhhhhed Holly and made her kneel down in an attempt to hide? Perhaps he had been taking Holly back into the house and was spooked, and decided to take Holly with him. So they leave out through the carport again. Clint sees them passing the kitchen window heading to his right, which would be roughly North.
