The property to the north is approximately 125 acres and is agricultural. It has no buildings on it. It is owned by the same person as the property to the west of the Bobo property with an additional 50 acres and is also agricultural without any buildings on it. I wonder if this property is used for hunting purposes and if so, I wonder if her abductor is someone who hunts that property and is familiar with it, maybe someone who knows the owner of that property. The owner of these properties appears to live elsewhere in the town and there is at least one road in the town with the same last name as the owner. They appear to be a long established family.

Additionally, according to the property listings, the properties to the south of the Bobo property are farmland and only have 1 barn listed. The property across the road is also agricultural with no buildings.
So essentially, the Bobo property is surrounded by unoccupied property on all sides.
The closest residences appear to be on the opposite side of the property directly south of the Bobo's, as well as a home across the street from that property and another mobile home just to the south of that property. That is a fair distance for a neighbor to be able to hear which direction a scream came from and to call 911. JMOO!
I added those residences to the map, since they are somewhat difficult to see.
