I wonder if LE asked him to take a polygraph. He's probably innocent, but sometimes another tool can help bring out deception, just in case LE missed something.
I don't believe LE even had enough for a search warrant. They only looked through his trailer (per Mr. Renner's blog) after it was sold and being towed on the highway (under the motor vehicle act). It's doubtful LE even considered him a POI. It has been floated out there on the "cyber ether" that the contractor only came forward with the sighting of a runner 5 miles down the road after a reward was posted. Again, though, only other poster's musings.
