A couple of things...
First, he either knew the elderly couple and choose them for a reason
or
Second, when he dropped the truck he walked to the nearest house.
My guess is the first...he knew these people were elderly, would be easy to take advantage of...he probably took car, money, food, etc. and money would bet that they live in a somewhat secluded area, possibly a farm house etc., where no one could see any activity off the main road.
The thing that baffles me is....he had to know LE knew is was the main suspect, the elderly couple would be easy targets to take advantage of without causing harm to them, and it wasn't like they were going to let his secret out, he had to know he was wanted, so with that said, what would be the point of harming the elderly couple. He could have robbed them easily without taking them or hurting them.
This doesn't look good - they're probably on their property too. I hate to say that.
Finally, the ex of Tiffany comes from a great family, he's had a rough last year.
The elderly couple does know SL as they sold him his house.
Sadly, I don't think this is going to end well either and I fear they may not be alive now too.
This guy needs to be found and quick!
